The loose diamond certification process is an easy way to boost buyers’ confidence during the shopping process. When diamond certification is conducted by a reputable organization, such as the Gemological Institute of America (GIA), buyers can rest assured that the diamond is a genuine, natural diamond, rather than grown in the lab as a synthetic diamond. It also reveals whether or not a loose diamond has been treated.
Since no two diamonds are alike, the certification process assigns value to each individual stone. For example, the GIA uses an internationally recognized grading system to compare common attributes. This system, known as the “four C’s”, determines each certified diamond’s value by grading its color, clarity, cut, and carat weight.
Diamond Color
To determine the color of a diamond, a gemologist compares the stone to a color classification chart ranging from D (colorless) to Z (light yellow or brown). The loose diamond is compared to a set of master stones representing the colors on the chart.
Certified diamonds classified as “D” are colorless, while those graded “Z” are light yellow or brown. Since truly colorless diamonds are extremely rare, the majority of diamonds used in jewelry are designated as “H” or “I” and have a slightly yellow tint—described by gemologists as “nearly colorless”.
Diamond Clarity
Natural diamonds are formed under considerable heat and pressure, giving most of them internal or external inclusions that can impact diamond clarity. There are eleven grades of diamond clarity, ranging from flawless (no inclusions visible under a magnifying glass) to I3 (inclusions visible to the naked eye).
Much like the human fingerprint, inclusions are markings that distinguish one loose diamond from the next. During certification, gemologists plot a diamond’s inclusions on a diagram to indicate its distinctive features—those that no other diamond has—which then get added to the certification paper. This diagram helps match each diamond to the proper certification, so buyers can be sure the diamond they’re evaluating is the same one on the report.
Clarity tests also reveal authenticity, helping gemologists determine whether a diamond has been treated. Inclusions verify that a diamond is natural, rather than a synthetic look-alike. If it is determined that a diamond has been treated, that will be noted on the certification report.
Diamond Cut
While people often think of cut as indicating the shape of a diamond (i.e. square or round), the term is used during certification to describe the stone’s sparkle and brilliance on a range from “Excellent” to “Poor”. To assist with cut grading, gemologists place each loose diamond in a machine, rotating the stone 360 degrees and capturing every one of its facets to generate a sophisticated 3D model. Many factors are considered to determine the stone’s grade, including proportions, girdle thickness, culet size, polish, and symmetry.
Diamond Carat Weight
As counter-intuitive as it might seem, bigger isn’t always better when it comes to diamonds. Value is determined by all four of the “C’s”, not just its weight.
To determine carat size, certified diamonds are placed in high-tech, sealed-chamber electronic scales. The weights, which measure how close a diamond is to one carat (200 milligrams), round each stone to a second decimal place to arrive at a standard carat size measurement.
Upon completion of the rigorous certification process, a certified diamond is given a report indicating its grading for each of the four C’s, along with other pertinent information. Buyers can ask to see this report before purchasing a certified diamond; some grading agencies also allow them to check the information online.

Carlos Defex is the newest member of the Brilliance team, bringing with him a lifetime of knowledge and passion for jewelry. As the head of our custom jewelry department, Carlos will be working tirelesly to bring his own style and experience to Brilliance jewelry. The Brilliance Blog took some time to sit down with Carlos so that you could get to know him better.
Brilliance Blog: How long have you been in the jewelry business?
Carlos Defex: I started in the jewelry business nearly 15 years ago when I received a bachelor’s degree in Metals and Fine Jewelry with specialization in Jewelry Design. The passion that I have for jewelry has taken me to different cities around the world, where I‘ve been exposed to different life styles and customs. I believe that my experiences shows in the caliber of jewelry that I design.
BB: What made you decide to go into jewelry?
CD: What I love about jewelry is the transformation of rare materials that are found deep beneath the earth through millions of years of evolution. To be able to transform those materials and give them an expression related to love and passion. I believe that jewelry is the perfect blend between science, art and nature.
BB: People obviously enjoy jewelry for the beauty and style, and you can tell a lot about a person by the kind of jewelry they are wearing. What can you say about different cultures and their jewelry?
CD: Jewelry has played an important role throughout the history of human kind, and has been a channel to communicate emotions, status, power, and beliefs. We can see it from the first Homo sapiens in Africa, barbarian tribes like the Celts, Mayans in Central America, or the Andean cultures in South America that created beautiful pieces of jewelry. India has probably the longest tradition of jewelry making and trading, dating back as far as the people of the Indus Valley Civilization more than 1,500 BC; also they were the first country that mined diamonds. As we can see, jewelry has been linked with the development of different cultures throughout the history and will be part of more generations to come.
BB: What do you find special about Brilliance, and what do you hope to add?
CD: Our jewelry is versatile, stylish, and at the same time shows a sense of tradition. It is made for the versatile woman that goes to work, takes care of the family, drives her kids to soccer games, and goes to a dinner party or cocktail at night; our jewelry is made to wear at any occasion. I believe that jewelry needs to be fun, enjoyable, accessible, and at the same time rare or unique.
BB: So we’ve heard about your passion for jewelry. Do you have anything to say about diamonds and other precious gems.
CD: I frequently hear from people, “it is only a rock”. And they might be right. But it is not just any rock…it is “The Rock”, whether we are referring to a loose diamond, emerald, ruby, sapphire… these precious gems contain thousands of years of history, culture, and chemical and physical changes occurring deep within the earth. These are rare materials that symbolize a tradition, a special moment for the individual and the collective. Matched with the right jewelry, a precious stone can say who you are without words, a sensual piece of distinctiveness and self expression.
Are you considering buying EGL diamonds? If so, is the diamond grading report issued from EGL International or EGL USA? When purchasing an EGL certified diamond, it’s important to understand the fundamental differences between these organizations.
In 1973, Guy Margel opened the first European Gemological Laboratory (EGL) in Antwerp, Belgium. Today, EGL International has a presence in all major diamond sourcing cities in the world, including Antwerp, Johannesburg, Paris, London, Tel Aviv, Seoul, Istanbul, Mumbai, Delhi, and Cape Town. Each of the EGL facilities is an independent franchise operating under the EGL International brand.
Originally, EGL USA was a franchisee of EGL International. In 1986, it became independent of the European organization, and today operates as a completely separate company. Headquartered in New York City, EGL USA has laboratories in Los Angeles, Vancouver, and Toronto.
Grading Differences
Diamond grading is a subjective skill. When these skills are put to the test at laboratories maintaining independent diamond grading standards, it’s no surprise that there are sometimes discrepancies. EGL International maintains 10 independently owned and operated testing facilities around the world, while EGL USA’s three laboratories are owned and operated collectively as one entity. This means that EGL USA is able to maintain much more uniform and rigorous standards than EGL International.
Generally speaking, EGL International diamond grades are more lenient than those issued by EGL USA. As a rule of thumb, EGL USA certified diamonds are comparable to EGL International certified diamonds that are graded one color grade and one clarity grade higher. For example, an EGL USA diamond that’s graded H in color and SI1 in clarity would be graded as G and VS2 by EGL International.
Choosing an EGL Certified Diamond
Approximately 23% of certified diamonds sold on the Internet are EGL-graded. When purchasing one of these diamonds, be sure to look for a diamond report with an EGL USA logo. This report will state, “Member of the EGL USA Group”, with certificate numbers preceded by either US (United States) or CA (Canada).
Currently, EGL USA is attempting to stop the import of loose diamonds with EGL International reports. Diamond reports issued by European labs have a universal report with the country of origin printed on the cover card. Each European lab has its own numbering or lettering convention, as outlined in the examples below:
EGL Belgium: Alphanumeric characters; certificate code begins with A
EGL South Africa: Begins with SA
EGL Turkey: Begins with T
EGL India: Begins with letters D – J; maximum of 9 digits
EGL Israel: Usually begins with a number 2
If you’re purchasing an EGL-graded stone, keep in mind that EGL USA has tighter grading standards – especially with regard to diamond color and clarity. However, there’s no guarantee that all EGL USA certified diamonds are better than those certified by EGL International. Although the EGL International’s looser grading standards have made their certification slightly less credible, they have also caused the prices of EGL International certified diamonds to be lower in the diamond market. Therefore, you can sometimes get a great bargain for an EGL International certified diamond that has been under-priced.
When in doubt, it’s a good idea to consult with an experienced jewelry and diamond professional before making your purchase. Contact a Brilliance diamond expert at 866-737-0754 for guidance on which diamond certification is right for you.

Here at Brilliance, we want each customer to make an informed decision when choosing a certified diamond so that they will be completely satisfied with their purchase. Although a benefit of purchasing a certified diamond is that a consumer can compare diamonds based on the Four Cs and other factors, it is important to note that the grading standards of the various laboratories vary. This variation results in a discrepancy in the quality of diamonds graded in different laboratories, even when they are graded the same color, clarity, or cut.
Of the five laboratories that certify the loose diamonds we offer at Brilliance, the Gemological Institute of America (GIA) and the European Gemological Laboratory (EGL) are by far the most popular. When deciding which certification to go with, it is important to understand the vital differences between the grading techniques of the two laboratories.
First some history…
The GIA was established in 1931 and is considered worldwide as the leading authority in gemology. Their staff of 1,400 employees includes scientists, certified diamond graders, and educators. They currently have locations in all major diamond cities in the world, including Carlsbad, New York, Moscow, Florence, Antwerp, Tel Aviv, Mumbai, Gaborone, Johannesburg, Beijing, Hong Kong, Seoul, Tokyo, Osaka, Taipei, and Bangkok. GIA is credited with standardizing the grading industry by introducing the Four Cs and other widely used grading techniques. They offer diamond grading and laser inscription services, as well as a wide range of educational services for diamond professionals and consumers.
Founded in Europe in 1974, the EGL International and the EGL USA laboratories employ over 1,100 scientists, diamond graders and educators. Their EGL International locations are found in Antwerp, London, Paris, Mumbai, Johannesburg, Hong Kong, Seoul, and Tel Aviv. Their locations in New York, Los Angeles, Vancouver, and Toronto are considered part of EGL USA. The EGL is known for introducing grading techniques for diamonds weighing less than one carat and for establishing the “SI3” rating for diamond clarity.
Comparing diamonds of the “same” quality
In general, Brilliance suggests choosing a GIA certified diamond over an EGL certified diamond. Loose diamonds GIA certified are graded using strict standards that are consistent among the various GIA locations. Each GIA diamond is carefully evaluated by at least four expert gemologists who are chosen at random to guarantee an unbiased evaluation. The EGL’s grading standards are more lenient and vary among the EGL locations, with EGL USA locations generally grading on a slightly stricter scale than its International counterpart. As a general rule, an EGL certified diamond will compare equally in quality to a GIA certified diamond that is graded two color grades and one clarity grade lower. For example, an EGL diamond graded G in color and VS2 in clarity is comparable to a GIA diamond graded I in color and SI1 in clarity. As a result, GIA certified diamonds are considered more valuable and provide the consumer with more confidence in the product they are purchasing.
However, there is a benefit to choosing an EGL certified diamond. Due to the discrepancy in the grading standards used, an EGL diamond graded the same color and clarity as a GIA diamond will be less expensive. This is seen as an advantage to those who consider the ratings stated on the certificate a priority when choosing their diamond. If you are interested in purchasing an EGL certified diamond and would like to have an expert evaluate it, contact a Brilliance diamond expert at 866-737-0754.
You don’t have to visit a natural history museum to have an up-close and personal encounter with a geological phenomenon. In fact, if you’ve got a diamond engagement ring, diamond earrings, or a diamond bracelet, you may be wearing one right now! To fully understand the natural wonder of diamonds, let’s take a look at how they’re formed.
The word “diamond” originates from the Greek word “adamas”, meaning indestructible and invincible. Diamonds are the only gems composed entirely of carbon. The sixth most common element on earth, carbon is present in all organic molecules. With regard to diamond formation, it’s the particular arrangement of the carbon atoms that makes each stone truly unique.
Diamonds are the crystalline form of elemental carbon, with carbon atoms arranged in an isometric-hexocrahedral crystal lattice that is remarkably hard and disperses light well. In order for diamonds to form, carbon must undergo very specific conditions. The air pressure must range between 45 and 60 kilobars (60,000 times normal air pressure at sea level) and the temperature must be between 1652 and 2372 F (900-1300 C).
Diamonds are formed deep within the earth’s lithospheric mantle, located 75-120 miles beneath the earth’s surface. At these great depths, the carbon atoms in the earth’s mantle and in fossilized microorganisms are subjected to intense pressure and temperature changes. When carbon-rich rock submerges in the earth’s mantle, carbon atoms become liquefied. When the temperature dips and specific pressure and temperature conditions are met, the carbon atoms then crystallize and form diamond-bearing rock.
Once the loose diamond has formed and hardened, it can take thousands of years for geologic events to bring the crystals to the surface where they can be mined. One way diamonds are brought to the surface is via volcanic pipes, which are carrot-shaped magma channels of deep-origin volcanoes. In volcanic pipes, magma has carried deep-formed rocks and minerals to the surface where they can be mined as a primary source of diamonds. Secondary sources of diamonds include areas where water or wind has eroded the surface of volcanic pipes, such as alluvial deposits that are found along riverbeds and shorelines.
The diamond ore mining process is labor intensive, and yields a very small fraction of actual diamonds. Only 25% of the mined diamonds are considered of a high enough quality to be used in fine jewelry, with the remainder being used as abrasives or for the industrial use of diamond cutting, drilling, grinding, and polishing equipment. Today, most gem-quality diamonds are mined in Brazil, Russia, South Africa, Canada, and Australia.
Understanding how diamonds are formed results in a greater appreciation of this geological marvel. From the time carbon atoms are liquefied in the earth’s lithospheric mantle until they reach your finger or earlobe can span an astonishing 45 million years. The diamond’s longevity, brilliance, and complexity combine to make it the consummate symbol of eternal love and loyalty.
The International Gemological Institute (IGI) is the world’s largest independent laboratory for diamond and gem grading, certification, and valuation. Founded in Antwerp in 1975 by a staff of three, IGI has grown to include more than 450 professionals, spanning the globe with offices in New York City, Hong Kong, Tokyo, Bangkok, Dubai, Toronto, Los Angeles, Tel Aviv, and Mumbai. The only ISO 9001:2000 certified international gemological organization, IGI adheres strictly to an internationally accepted system for diamond grading. With a single governing body and rigid standards of excellence, the Institute provides priceless peace of mind, arming consumers with the knowledge they need to feel confident and secure when purchasing loose diamonds.
Today’s certified diamond and gem consumers are far savvier than their predecessors, demanding quality and professional knowledge in addition to beautiful jewelry. Intelligent consumers want to understand the differences between certified diamonds so they can make educated decisions about their fine jewelry and engagement ring purchases. IGI’s consumer-focused grading, identification, and appraisal reports play an integral role in consumer education, ensuring that the quality-conscious consumer is confident with their diamond purchase.
In addition to diamond quality, today’s consumers also demand verification that their diamonds are conflict-free. An IGI Certificate of Authenticity states that the stone is in full compliance with the Kimberley Process, the USA Patriot Act, and the US 2003 Clean Diamond Act, and attests that the diamond was responsibly mined and ethically sourced, ensuring that it is “conflict free”.
In addition to the Certificate of Authenticity, IGI generates Diamond Reports and Colored Stones Reports. An IGI Diamond Report provides reliable and accurate data regarding the diamond’s grade, based on an internationally recognized grading system. Independent, unbiased gemologists use state-of-the-art equipment and cutting-edge technology to grade each loose diamond for cut, color, clarity, and carat weight. An IGI Colored Stones Report describes a gemstone’s specific variety, shape, cut, carat weight, color quality and transparency factor, country or origin, and whether the stone is natural or synthetic.
The comprehensive information contained in the Diamond Report and Colored Stones Reports is used to generate IGI’s Gemological Appraisal Reports, the most reliable and accurate valuation documentation available today. In addition to providing coverage information for insurance companies, IGI Gemological Appraisal Reports provide vital documentation for estate executors, financial planners, public accountants, retailers, consumers, and jewelers. IGI Diamond Reports, Colored Stones Reports, and Gemological Appraisal Reports can be obtained at the point of purchase, or independently by sending diamonds and gemstones directly to the IGI.
IGI’s expanded services include Laser ScribeSM, table branding, diamond repair, jewelry engraving, and photography. With Laser ScribeSM, gemologists use lasers to inscribe numbers, letters, logos, personal messages, and trademarks on the girdle of the diamond so the stone can be easily identified. This laser inscription is visible only under 10x magnification, and does not affect the quality of the stone. Laser technology is also utilized with IGI’s jewelry engraving. Table branding allows companies to permanently affix their trademark or logo on the upper, largest facet (table) of a diamond. This logo is only visible under special viewing equipment, and does not affect the diamond’s grade. IGI’s master polishers repair diamonds that have been damaged, or remodel stones with out-of-date cutting styles or poor facet arrangements.
Founded in Antwerp in 1982, the IGI Gemology School currently has branches in Mumbai, Cavalese, Dubai, and Toronto. The schools promote IGI’s mission of education and knowledge by offering courses in polished diamonds, rough diamonds, colored stones, pearl grading, and jewelry design. IGI’s prestigious gemology training courses attract thousands of diamond dealers and jewelers from 90 countries annually, with courses available in many languages. IGI courses are taught by highly skilled, internationally recognized gemologists, and emphasize comprehensive and practical learning techniques. For those not able to attend an IGI Gemology School, the Institute offers an IGI Long Distance Course, a home study diamond correspondence course.
At Brilliance, we offer certified diamonds by IGI in our diamond search. To find out more about the IGI, click here.
If you’ve ever purchased a diamond solitaire, you’re most likely familiar with the “4C’s” of diamond grading – cut, clarity, carat, and color. Until the recent development of the Gemological Institute of America’s Cut Grade, a certified diamond’s cut has been the most widely debated of this diamond grading criterion.
A diamond’s cut is the only grading criterion not determined by the natural characteristics of the stone. Contrary to most assumptions, the cut of a diamond does not refer to the shape of the stone, but to its proportions (width and depth), polish, symmetry, and facet uniformity. It’s these factors that determine the diamond’s levels of brilliance, fire, and scintillation.
A diamond’s brilliance is determined by its ability to reflect white light back to the eye, and its fire is its ability to reflect colored light. Scintillation, or a diamond’s sparkle, is a combination of the stone’s brilliance and fire, resulting in “flashes” when a diamond moves in the light. With shallow cuts, light is lost through the bottom of the stone, and with deep-cut diamonds, light escapes out of the sides. The most expertly cut diamonds reflect light back to the surface, bringing the brilliance of the diamond to the forefront as it sparkles in your engagement ring.
The Gemological Institute of America (GIA) is a non-profit organization whose mission is to ensure public trust in gemstones. Recognized as the foremost authority in gemology, the GIA has recently developed its Diamond Cut Grading, which categorizes each loose diamond’s cut grade as excellent, very good, good, fair, or poor.
The GIA’s Diamond Cut Grading System for round, brilliant cut diamonds is a comprehensive grading system based on fifteen years of extensive light-behavior computer modeling and statistical information gathered by more than 70,000 human observations. This scientific assessment accurately defines the factors of a round brilliant diamond. While many of these were already well known in the diamond industry, some newly discovered factors resulted in techniques that produced quality diamonds from stones that were previously thought unusable.
For loose diamonds, the GIA’s rating system grades a brilliant cut diamond’s face-up appearance, using light-behavior computer modeling and algorithms to predict brightness, fire, and scintillation. These measurements, along with the diamond’s durability, polish, and symmetry, determine the GIA Diamond Cut Grade.
More than 99% of the diamonds graded will fall into Diamond Cut Grades of excellent, very good, or good. A range of characteristics and proportions define each grading parameter. The GIA Diamond Cut Grading System is designed to educate consumers, arming them with the confidence they need when making diamond purchases. If you purchase a certified diamond graded as “Excellent”, you can rest assured you’ll receive an exquisite stone with high levels of brilliance, fire, and scintillation.
Although the GIA Diamond Cut Grades are currently assigned only for round, brilliant cut diamonds, the GIA is currently researching diamond cut grades for emerald and princess cuts, and will share this data with the diamond industry when their research is complete.
At Brilliance, we offer GIA certified diamonds with cut grades ranging from Excellent to Fair to ensure the largest selection.
To determine the quality and value of a loose diamond, each of the “four Cs”—cut, color, clarity, and carat weight—is individually evaluated by an expert gemologist. Each of these characteristics has a significant impact on the overall appearance of the stone.
In the fine jewelry industry, the designation of a loose diamond’s color is actually used to refer to the presence or absence of color in the stone. An ideal diamond is colorless and pure white, although these are extremely rare and typically very expensive. Most stones are colored with a slight yellow or brown tint. Diamonds with some amount of color can be attractively set in a classic yellow gold band, while near-colorless stones usually look best when mounted in a white gold or platinum setting.
The less amount of color in a diamond, the more desirable and valuable it is. An exception to this rule is the “fancy diamond,” a term used to describe a stone with a naturally occurring tint, such as pink, blue, green, black, champagne, or (most rarely) red. With fancy diamonds, darker, more intense colorations increase their beauty and value.
The GIA (Gemological Institute of America) uses a very precise color grading scale to evaluate loose diamonds:
D, E, F: These high color grades indicate diamonds that appear colorless to the naked eye.
G, H, I: Also a high grade, these near-colorless diamonds appear white to the naked eye, but include very trace amounts of yellow when viewed under magnification.
J, K, L: These grades may appear colorless to the consumer, but a trained jeweler will be able to distinguish a slight yellow tint.
M, N, O: These grades indicate a light yellow tint, which can usually be detected by the untrained eye.
P, Q, R, S, T, U, V, W, X, Z: These grades are used to indicate stones with a darker yellow tint.
At Brilliance, we offer only premier certified loose diamonds rated “M” and above. Each of our certified diamonds is appraised by an expert gemologist, arriving with a document detailing its quality characteristics and overall value.

With 83% of American and Canadian brides receiving engagement rings from their fiancées, the jewelry market continues to enjoy a steady demand for certified diamonds. A timeless heirloom to be passed down from one generation to the next, a certified diamond is a perfect choice for symbolizing a couple’s eternal love and devotion.
When shopping for a diamond engagement ring, one of the most important considerations is how much to spend. According to the standard rule of thumb, a buyer of a diamond engagement ring can expect to spend an amount equivalent to 2-3 months of their salary, a guideline that originated with De Beers, the world’s largest diamond producer. However, many modern couples choose to spend significantly more than this benchmark, saving up to invest in a high-quality center diamond.
Although economical diamond engagement rings can be found, they’ll likely require a sacrifice in the areas of cut, color, clarity, or carat weight. Celebrities are on the other end of the spectrum: Scarlett Johanssen’s engagement ring was rumored to cost $30,000, while Mariah Carey’s fiancée purchased hers for a staggering $2.5 million.
Before beginning the diamond ring shopping process, there are several factors the couple should consider to determine a specific price range that accommodates their lifestyle and jewelry tastes.
1. The couple should make a list of the preferred characteristics for the diamond engagement ring, such as shape, size, and setting. One bride might prefer a pear-cut diamond, while another may be less concerned about the diamond’s shape and more interested in its color.
2. Financially, the couple should take stock of their current salary, debt amount, and credit rating. If they plan to finance the cost of the ring, they’ll need to determine the amount they can afford for the monthly payment. If a major purchase has recently been made, such as a house or car, this can sometimes impact the available funds for the diamond.
3. Opting for a simpler setting is a great way to get more diamond quality for the dollar. Many couples choose to focus on investing in high-quality loose diamonds initially, and then upgrade to a more elaborate setting later.
4. If a couple is planning an extravagant wedding and reception, they may not have as much to invest in the ring. On the other hand, opting for a small, understated ceremony may allow the couple to indulge in their dream certified diamond.
In addition to signifying a lifetime of love and loyalty, a diamond is a financially sound investment that will continue to hold its value for years to come.
