Ethically sourced and carefully crafted, our MONA Radiant Studs emit a dazzling radiance. They are a twist on your traditional studs.  Each Canadamark certified diamond comes with an assurance that your diamond is authentically Canadian. When a Canadamark diamond is cut and polished, a unique serial number is assigned to the stone which is then laser engraved on its girdle together with the Canadamark logo.
