Jewelry Appraisal’s Case Study: Is It A Fancy Light Yellow Diamond Or Something Else?
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.
Fracture-filling in diamonds: a treatment to enhance diamond clarity but it needs to be disclosed to the consumers
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).
How To Date Diamonds?
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.
Clarity Enhancement in Emerald and Its Affect On Value
It is a common practice in the trade that virtually all emeralds have been fracture filled by oil, resin or other substances to enhance their clarity, sometimes to enrich their color, or even durability. The geological conditions where emerald grows just make it very rare for emerald to be eye-clean. Therefore, emerald is classified as Type 3 according to the GIA colored stone grading system.
