(jckonline.com) - Gemological Institute of America is unveiling a new service that tracks the origin of select polished diamonds—and provides the retailer with a new way to tell a stone’s story. Matt Crimmin, GIA vice president of laboratory operations, admits that the Mine to Market (M2M) program does not represent a complete solution to determining a diamond’s provenance. “If you just gave me any polished diamond, I can’t tell you what mine it came from,” he says. But the program, two years in development, does represent a seeming step up from present-day methods of diamond tracking, as well as a potentially powerful new tool for selling gems.
