Guaranteed Grading
One of the first things you learn as a jewelry journalist is that grading documents that you get from a lab are called “reports,” not “certificates.” That’s because the results they give are opinion and not guaranteed beyond that. But now one lab, Gem Certification & Assurance Lab, actually does issue diamond certificates backed by a guarantee of accuracy. Until now, the lab has given itself one-grade wiggle-room in that guarantee. Yesterday, they tightened that to guarantee the specific quality and weight of the diamond described in the certificate. Of course, GCAL itself judges whether the grade is in fact correct (and, thanks to the Gemprint they take of each diamond they grade they can recognize each gem that is resubmitted for grading again.) You can’t submit a GIA report with a different grade and expect them to pay up. But GCAL’s parent company, Collectors Universe, has already paid consumers $391,000 under similar guarantees in its other divisions, like coins and stamps. Here’s how the new GCAL guarantee works: if you believe your GCAL-certified diamond does not meet the carat weight or quality grades stated within two years of the date on the certificate, submit your diamond for review. If GCAL determines that either the weight or quality grade is lower than the weight or quality grade originally assigned on the applicable certificate, or the diamond is not authentic, GCAL will either reimburse you for the difference between the current retail value of your diamond at the original grade or weight and the current retail value of your diamond at the newly established grade or weight or replace your diamond with an authentic, natural diamond of weight and quality grade as stated in the original certificate. Even without considering grading disputes, the guarantee will probably attract customers who worry about undisclosed treatment or synthetics.
yea..certified diamonds have lot of demand in the market.it gives the guarantee and assurance to customers.
