CERTIFICATES

IGL Diamond Certificate

The IGL Diamond Certificate provides a reliable and accurate documentation of a diamond’s identity and grade based on the internationally recognized diamond grading system. Using state-of-the-art equipment, each diamond is analyzed by several gemologists in order to provide the most accurate description of the diamond’s quality and characteristics. The carat, color, clarity and cut – commonly known as the 4 C’s of each diamond are clearly stated on each diamond certificate. Additional grading characteristics such as the finish, girdle, culet and fluorescence are also detailed on the certificate. A diagram of the diamond displaying any inclusions is also included on the certificate.

IGL Matched Pairs Of Diamonds Certificates

As every experienced gemstone collector knows - there’s no such thing as two perfectly matching diamonds which are identical in all respects. But it’s possible, albeit rare, to find flawless gemstones which are very close to perfect matches. When looking at the similarity of gems, the four C’s of each diamond needs to be compared – that of carat, cut, clarity and color. Ideally a pair will have been cut out of the same rough stone, and by the same cutter. Matching pairs are very rare in nature – particularly since both transparent and fancy color diamonds are so rare to find in the first place. And, the higher the grade of diamond, the harder it will be to find another to match it - finding one perfectly cut, flawless diamond is a rarity, but finding two is an exceedingly rare occurrence – these appearing only every few years.

IGL Jewelry Certificate

The IGL Jewelry certificate is used to document jewelry pieces and identify the characteristics of the precious stones featured in each piece. Each IGL Jewelry certificate features a description of the jewelry piece followed by a statement of the characteristics and grading of the precious stones found in the piece. A statement listing the quantity of gemstones featured in the piece as well as a grading report of the gemstone’s weight, shape, color, clarity, cut, proportions and measurements are featured in the IGL Jewelry Certificate. In addition, the identification, weight and content of any precious metals found in the piece are described on the certificate. As a further way to identify the jewelry piece, the IGL Jewelry certificate features an enlarged color photograph of the item. Upon request, the International Gemological Laboratory can easily convert an IGL Jewelry Certificate into an appraisal certificate.
