Companies dealing in diamonds get the services of the Gemological Institute of America (GIA), one of the most respected laboratories in the diamond industry, to generate diamond grading reports or diamond certificates, also known as diamond dossier or diamond quality document. The diamond certificate is a written report of the analysis of the diamond’s clarity, color, cut grade, and carat weight based on evaluations and analysis conducted by one or more gemologists, which may reach to as many as 15 depending on the diamond’s rarity or complexity.
The diamond grading report also contains the dimensions, symmetry, the angles and proportions of the facets as well as its cutting workmanship, imperfections, and other important characteristics. However, the report does not contain the appraised value of the diamond.
Although it does not contain the appraised value, it is still very important because it establishes the true quality and genuineness of the stone. Since most buyers are not experts, the report gives an objective comparison through an unbiased and professional examination. The diamond certificate likewise facilitates smooth transaction by providing assurance of quality and dependability as the basis for the gem’s price and insurance.
Many independent grading labs operate all over the world like the reputable GIA. Unfortunately, not every gem laboratory is identically qualified or knowledgeable, while some have questionable ethics. The GIA, which is not engaged in buying and selling diamonds, has become the leading authority on diamonds and the most respected laboratory in the world. Its reports on diamond quality are carefully drawn and show the exact position, size and shape of every internal inclusion and external blemish a diamond possesses and it is very strict in assigning color and clarity grades. Their grading reports have, arguably, achieved the highest ethical standards within the diamond industry.
To complete the evaluation of diamonds, there are appraisal certificates. While the certificate from gem laboratories identifies or authenticates the diamond, an appraisal evaluates the diamonds and assigns an appropriate value to the gem. An appraisal is performed by diamond and jewelry professionals engaged in the trade of diamonds. They can rely on certificates to back up their opinions if a certificate exists. Otherwise, they evaluate the diamond based on training and experience
After properly documenting the stone including its rarity and marketability, the appraiser determines the market value of the gem which may vary from one appraiser to another. The current market value assigned to the gem is a way of determining whether or not its insurance coverage is adequate. In insuring jewelry, all insurers require a copy of the jewelry appraisal with the application. Certificates and appraisals can shed light on the origin and genuineness of the jewelry as well as its insurability.
