Certificate

What’s in a Certificate?

A certificate is a blueprint of a loose diamond. Wholesalers, retailers, and consumers alike know a certificate as either a diamond grading report or diamond dossier. A certificate will tell a diamond’s exact measurements, weight, cut and overall quality. A certificate will precisely point out a diamond’s individual characteristics as well as be a useful tool when identifying a stone. When shopping for a loose diamond, considering stones that have a grading report will allow you to make an informed decision on which diamond will be ideal for you.
Your diamond grading report is supplied by one of the following organizations. Diamond grade definition may vary. Please click here to learn more

G.I.A.

Any diamond submitted to G.I.A. is ensured to have reliable and consistent grading. Anywhere from 3-6 separate gemologists will individually grade each and every diamond for an accurate final grade. G.I.A. grading reports are considered a hallmark of integrity throughout the diamond world, issuing two separate types of reports. One of the more common reports is the full-issued G.I.A. document, which contains the full description of the diamond as well as a plotting of the grade-setting clarity characteristics of that stone. The G.I.A. Dossier will have the full individual details of each diamond graded, but the plotting is not included. Both reports reference a unique serial number that has been laser-inscribed on the diamond’s girdle, allowing for verification of the stone under 10x magnification. With “Gemscribe”, your diamond cannot possibly be mistaken for any other. The serial number on your diamond will always match the serial number on your certificate.
Two other independent institutions also certify Jared® diamonds: I.G.I (International Gemological Institute) and G.S.I. (Gemological Science International). Both follow G.I.A. standards.

I.G.I.

The International Gemological Institute (I.G.I.) is the largest independent grading and appraisal organization in the world. Over 450 scientific technicians and gemologists examine hundreds of thousands of gemstones and jewelry items every year. I.G.I. has centers in Antwerp, New York, Bangkok, Mumbai, Tokyo, Dubai, Los Angeles and Toronto. It offers diamond and colored stone certificates, educational courses to the trade, and diamond laser inscription. The information contained in every I.G.I. Diamond Grading Report is also stored in the organization’s computer database, ensuring that you may, at any time, request and receive an update of your report if the need arises.

G.S.I.

GSI is an independent gemological laboratory that provides professional gemstone identification, grading and appraisal services exclusively to the fine jewelry industry. It is headquartered in the heart of New York City’s Diamond District and has offices abroad in international diamond centers. The foundation of GSI is built on innovative thinking, new technology, traditional values, and shared industry research. The result is a gem lab equipped to meet the evolving needs of the industry. GSI’s gemologists have vast expertise in diamond grading, both theoretical and practical. They are up-to-date about any new developments in the gemological and jewelry fields. Each diamond is examined by a minimum of four gemologists: two gemologists for color grade and at least two gemologists for clarity grade.

A.G.S.

A.G.S. is known throughout the diamond industry as grading top-notch Ideal-Cut round diamonds. Their high standards surpass those of any other grading laboratory when considering color and clarity as well as cut. If a diamond has been graded by A.G.S. Lab, it has met the standards of what is considered the perfect proportions, polish, and symmetry; and has been given a grade of “ideal” or a “000” rating. A.G.S. Ideal-Cut round diamonds are highly sought after in today’s market.

GemEx

GemEx Systems is an independent laboratory that provides certification on the light performance of a diamond, stating the measurement of fire, sparkle and brilliance for your Leo Diamond. This certification is known as the"Return of Light." The GemEx BrillianceScope® Analyzer, which uses patented spectrophotometer technology, measures a diamond’s white light (brilliance), color light (fire) and scintillation (sparkle). It then rates each of these three measures compared to other diamonds of the same shape. The scale for each shape was set by measuring thousands of diamonds to determine the highest and lowest amount of white light, color light and scintillation possible for each shape. The Light Performance Report includes the three bar graphs and also shows images of the diamond under five different light views used for measurement of Light Performance. It is important to know that superior performance in any of the three light categories yields a beautiful diamond.
