Creating Trust through Transparency
Legacy of Excellence
GIA was founded to help jewellers understand the gemstones they sell and it is our non-profit mission to spread gem knowledge throughout the industry and to the public. This means we conduct advanced gemmological research, which we use to create instruments that further enhance our research capabilities. Empowered by our instruments, GIA remains at the forefront of technology and ready to take on technological disruptions, such as new treatments and laboratory-grown gemstones.
Research is in our DNA
GIA researchers, developers and innovators work each day to discover solutions for identifying complex gem materials and treatments. Our instruments are born directly from these efforts. Designed specifically for gem retailers and professionals, they help you protect your bottom line and build trust with your clients.
New Challenges. New Tools.
The GIA iD100® uses advanced spectroscopic technology to distinguish natural diamonds from laboratory-grown (HPHT and CVD) diamonds and diamond simulants. The GIA iD100 can test colourless to near-colourless, green-to-blue and brown diamonds, as well as pink diamonds when used with the GIA iD100 Pink Diamond Software Upgrade.
The GIA DiamondCheck™ gives even more comprehensive results. It uses infrared technology to label tested stones as natural diamonds, treated or laboratory-grown diamonds, or non-diamond material. These and other GIA instruments offer retailers and customers the peace-of-mind they desire when buying diamonds.
This sophisticated and easy-to-operate desktop instrument combines advanced spectroscopic technology with GIA’s 60 years of diamond and gemstone identification research to distinguish natural diamonds from laboratory-grown (HPHT and CVD) diamonds and diamond simulants.Learn More
Lab Tested. GIA Approved.
From our gem cloths and tweezers, to our spectroscopes and refractometers, to devices that identify laboratory-grown diamonds, the equipment we use in our classrooms and sell in our online store is the same as that which we use in our laboratories. These instruments have proven accurate and reliable through extensive use by experts, students and retailers alike.
Practical. Effective. Trouble-free.
GIA instrument developers include scientists, engineers and jewellers who use the very instruments that they develop. This enables them to design instruments that are efficient, user-friendly and that will last for years to come.
