There are different types of gemstones available. Some gems are precious while others are semi-precious gemstones. Additionally, there are synthetic / manmade replicas available in the marketplace as well. That’s why it is important to check their authenticity and genuineness before making a purchase.

Gemstones certification

Gemstones are certified to verify their authenticity. Certified gemstones are evaluated on different parameters established by the gems and jewellery industry. These parameters are determined by quality and other characteristics. Gemstone certification is a report that includes tests and measurements done on gemstones by experts. These tests also check for enhancements and treatments done to enhance the appearance i.e color, shine etc.

A gemologist examines the details of a gemstone and after thorough examination issues a report known as Gemstone certification also referred to as Authentication Report.

Importance of gemstone certification

Diamonds and gemstones with similar appearance can have significant differences in their value. Even the experts need powerful analytic tools to detect synthetics, treatments and enhancement processes. There are a number of synthetic gemstones in the jewelry market, which increases the importance to check for the authentic certified gemstones. It is only advisable to buy the gemstones checked and approved by a gemologist or from a genuine verified dealer who has gemstones that are evaluated on the basis of quality parameters.

Third Party Certification

Gemstone sellers have legit certificates along with legit gemstones. People are often deceived in diamonds and sapphires as they are popular and hot favorite gemstones amongst buyers. Always, remember that the gemstone certificate is issued by an authorized third party and you must keep in mind that it cannot be issued by the gemstone dealer himself.

No gemstone dealer can sell gemstones and the third-party issued certificate is absolutely necessary. These certifications are crucial for buyers to check the authenticity and genuiness of gemstones.  

In gemstone jewellery business, a gemological laboratory plays an absolutely critical role. Every reputable dealer would want to be absolutely sure that he is correctly describing his goods, and buyers too, would want the assurance of an identification report from a respected gemological lab.

Some of the most preferred names for the expert grading of diamonds, gemstones and gem stone jewelry include IGI, Asian Institute of Gemological Sciences (AIGS) in Bangkok, AGTA-GTL (New York), CISGEM (Milano), GAAJ (Tokyo), GIA (Carlsbad), GIT (Bangkok), Gübelin (Lucerne) and SSEF (Basel).
