The Gemological Institute of America (GIA) reports three Moissanites with fraudulent inscriptions, which belong to natural diamonds, were submitted to the laboratory in Johannesburg, South Africa, in its fall 2020 issue of Gems & Gemology.
The font of the fake inscriptions was distinctly different from the GIA’s one. They were treated with GIA’s standard procedure to make the number illegible. The institute said that simulants are “often” submitted to the lab for diamond grading but are easily rooted out using the standard grading process despiteMoissanite has properties close to diamonds including their hardness and thermal conductivity.
“The possibility exists that a consumer could purchase this simulant thinking it was a natural diamond, especially with a deliberately misleading inscription,” Sicebiso Hlatshwayo, a supervisor of diamond grading noted.
