IGI Now Issuing Reports for Moissanite From Roseco
The reports will state that IGI has verified the material as lab-grown moissanite and provide the stone’s weight and shape.

The IGI Certificates of Authenticity state the lab has verified the material as man-made moissanite (there is natural moissanite, though it is extremely rare), while also giving the stone’s carat weight, shape and “colorless characteristics.”
IGI said it will issue the certificates for Roseco moissanite in all shapes and weighing between 0.50 and 5 carats.
Roseco will sell the IGI-certified stones both loose and set in stud earrings, solitaire rings and solitaire pendants.
The program is designed to protect consumers as an increasing number of synthetics, simulants and counterfeits come to market, IGI said.
“There are a lot of different gemstone and jewelry options on the market, which is great, but it can also be confusing,” IGI North American President Avi Levy said. “Our laboratory analysis and verification will help retailers and consumers be assured of the authenticity and quality of the Roseco moissanite they are selling and buying.”
IGI said it has issued gem identification reports on moissanite for years, as do other labs, including the Gemological Institute of America and the Gem Certification & Assurance Lab.
This report for Roseco, however, is the first to include custom information fields such as the Refractive Index and Dispersion comparison chart, the lab said.
A French scientist named Henri Moissan is credited with discovering natural moissanite, which he found near a meteor crater in Arizona in 1893. Scientists perfected the process of growing it in a lab in the 1950s.
The material has a higher refractive index than diamond at 2.69 and ranks between 9.25 and 9.50 on the Mohs hardness scale, above corundum (sapphire and ruby).
