What if the gemstone turns out to be fake? You certainly would not want to land up in such an embarrassing situation when you are trying to sell it!
Before Delving Deep Into The Certification Process, Let Us First Understand What Exactly Are Gem Certifications?
Gem certification is a document issued by the licensed gemological laboratory, which defines the various internal and external characteristics of a gem or a diamond.
Some certificates verify authenticity and weight, some specify color and clarity grades, which might also include identifying marks and a map of the stone. There are other documents that show if the stone has been treated with laser or is of natural origin.
Full Process Of Gemstone Certification?
Here Are Some important abbreviations important to understand how gemstones have been certified:
• N: This testifies that the gemstone is a natural gemstone and not enhanced.
• E: Enhanced gemstone using common accepted treatments (for example, heat-treating for sapphire and rubies or oiling for emeralds).
• I: A non-traditional enhancement was used (such as flux or lead glass filling in rubies).
• C: The gemstone has been coated with a substance to alter its appearance or achieve a desired effect.
• B: Indicates the gemstone has been bleached or lightened.
• H: The gemstone has been heat treated.
• L: Indicates laser drilling to remove dark inclusions in diamonds.
• O: The gemstone has been oiled.
• G: Irradiated gemstone by gamma or electron bombardment.
• R: Irradiated gemstone by neutron bombardment.
• S: Indicates a bonding element that has been introduced to give the gemstone durability.
• W: Wax or oil is used to improve a gemstone’s appearance
• U: A diffusion treatment was used to alter the appearance of the gemstone.
Simply put, gemstone information includes the following details:
• Quality of gems: Natural or synthetic.
• Shape and cut
• Carat Weight
• The specific gravity of the stone
• Refractive index and hardness
• Color of the gems
Results That You Should Consider
Certified gemstones are also labeled for inclusions, which is common in natural gemstones. In fact, they also help in determining the origin of the gemstones.
Moreover, the way the gemstones have been treated will decide if you are accepting the gemstone treatment or not.
Getting A Gemstone Certification
If you are investing a handsome sum in buying a gem, ensure that it gets proper certification. Therefore, avoid the following:
• Any verbal communication from the jeweler about the authenticity of the stone
• A seller-issued certificate
Remember, it is fine to be issued a certificate by the seller, only if it has been provided by a third party who has no financial stake in the transaction.
It is best to get a gemologist to certify the gemstone, but it is always recommended to certify the stone by giving it to the lab for testing.
A gem lab has all the necessary equipment to test the authenticity of the stone and it does not have any stake in proving the seller right because its reputation would be at stake in that case.
Some of the leading international gemstone testing labs also try to certify the origin of the gem, but that involves a lot of costs and is certainly not recommended.
Some of the most respected Gemological Institutes are the Gemological Institutes of America(Mumbai), The Gem Testing Laboratory (India) and the IGI (India).
These organizations meet even international standards because of the way they treat each case analyzing the gemstones thoroughly and giving away all the information that is required for the buyers or the sellers.
Remember, a gemstone certification may cost you a lot of money, but consider it to be a one-time investment for a life-long profit.
