Types of EDL Certificates

Diamond certificate

The EDL 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.

Jewelry certificate

The EDL Jewelry certificate is used to document jewelry pieces and identify the characteristics of the precious stones featured in each piece. Each EDL 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 EDL 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 EDL Jewelry certificate features an enlarged color photograph of the item. Upon request, the European Diamond Laboratory can easily convert an EDL Jewelry Certificate into an appraisal certificate.
