You deserve to know what you are selling – to protect your customers as well as your business and your reputation.
It is with trade and consumer protection in mind that GIA, the most trusted organization in diamond research and diamond grading, offers innovative diamond detection services and technology, like the GIA iD100®.
GIA iD100®: Your Defense Against False Natural Diamonds
In under two seconds, the GIA iD100® can identify a diamond as natural with 100% accuracy. It is a small, yet powerful desktop instrument that makes diamond testing convenient. Test both loose and mounted diamonds from the convenience of your own store and use it for demonstrations to increase client confidence.
Few other diamond detection machines can match the speed and precision of the GIA iD100®. To protect your business reputation, this speed, accuracy, and convenience are crucial.
With the GIA iD100®, simply point its probe at a stone’s table to receive a result; the probe can be manipulated to reach every diamond in mounted jewelry and can read stones as small as 0.9mm in diameter. Results are easy to read. You don’t need to interpret graphs, colors, reference charts or data to know whether your stone is natural. In just two seconds, you get a simple “Pass” for natural diamonds and “Refer” for stones that need further testing.
In the event that your stone needs further testing, let the experts at GIA tell you the identity of your stone.
For a limited time, GIA will offer a complimentary service to verify GIA reports, confirming that a diamond with a GIA inscription matches the inscribed GIA report number. GIA graded diamonds, with or without an inscription, may be verified via GIA’s Report Confirmation Service.
"Combatting this fraud is vital to protecting the public and ensuring their confidence in gems and jewelry – this is GIA’s mission,” said GIA President and CEO Susan Jacques.
“We, like Tiffany, Cartier and other well-known global companies who are vigilant about protecting their valuable brands from counterfeiting and fraud, will take vigorous action to protect GIA and the trust consumers place in us.”
