"Gemstones have a beauty unlike anything else because they allow light inside and refract it" Gemstone is an invaluable nature's lovely unique creation which cannot compare with any other source in the entire world. On the other hand customers seek for the best, genuine, worthy gemstone when they purchase for their own use. That's where the role of Gem testing plays important in the trade.

Each Gemstone is an invaluable superb creation of Mother nature. Each stone consists of its unique color combination and unique beauty in it. Each stone is valued according to its uniqueness. SGL is principally focused on the identification and characterization of these high-quality gemstones which are from mine to market. We also do focus on the identification of gemstone imitations, synthetics and new gem treatments. Color grading and gemstone color branding, such as the well-known Pigeon’s Blood and Royal Blue etc. is our final area of characterization of gemstones.

New methods of production of high-quality gem imitations for precious gems such as Ruby, Sapphire, Diamond and Emerald as well as other gem species are added to the gem market everyday. Rather than these imitations new types of treatments are added to improve stone’s appearance. Here comes the value of keeping trust in a professional gem testing report. SGL trying its best to keep the customer’s trust and would add much knowledge regularly to improve the testing quality.
