Gemstones have long been the fascination of mankind and even today, beautiful and valuable gemstones are coveted all over the world. But can you really tell whether the gemstone you bought is the real deal?
In today’s market, it is becoming increasingly common to encounter synthetic and imitation gemstones, or natural gemstones that have been treated using one or more ingenious enhancement methods – these are materials that are difficult, or even impossible to distinguish from natural gemstones just by eye.
The GT200 series, Gem Identification Methods, is a follow-on course from the first course in gemmological foundation, and is intended as a practical guide for determining the true identification of gemstones with proper gemmological procedures and equipment. There will be ample opportunities for participants to have hands-on gem identification practice with natural, synthetic, imitation, and treat gemstones using a battery of tools provided in this programme.
Kindly note that this is an advanced course that requires the prior completion of GT100 - Gem and Jewellery Trade Secrets Certificate.
