On my appraisal card it says the World Gemological Laboratory. Who are they and are they credible?
The World Gemological Laboratory is a grading laboratory that determines the cut, color, clarity, and amount of treatment, if present, from loose diamonds and gemstones. According to their website (http://www.worldgemlab.com/) they were “founded to protect buyers from inaccurate Diamond and Jewelry grading reports.” Their mission is “to provide full grading disclosure so buying and selling is as safe as possible.” Their diamond and jewelry grading reports are regarded as an excellent indicator of value, frequently being requested as the grading report of choice among buyers and sellers of diamonds and jewelry.
