Jewelry appraiser Trang Pham, GIA Graduate Gemologist, owner of La Jolla Gem Appraisal has won the Rising Star award 2022 by the prestigious American Society of Appraisers (ASA). This is another step in proving her commitment with the profession she is passionate with.
In the trade, it is essential that laboratory-grown diamonds can be identified because consumers need to know what they are buying, and because there are often significant price differences between them and natural gemstones. It is increasingly important for gemologist appraisers to make that call of diamond origin (natural or synthetic) when appraising jewelry to produce credible reports for their clients.
There are many diamonds (both loose and mounted stones) that come across my desk on a daily basis for inspection as a part of the appraisal process. One of them is this diamond. It is an otherwise I3 in clarity before treatment (I3 is the lowest clarity grade in the GIA diamond grading system that I3 diamonds are highly included by fractures, crystals and other types of inclusions).
Scientists estimate that the earth is about 4.6 billion years old. According to GIA, research published in 2010 indicates that the youngest known diamonds—found in a Brazilian kimberlite—are just 107 million years old. On the other hand, the oldest known diamonds—from Canada’s Ekati mine—are as much as 3.5 billion years old.
