According to the report, this advancement is important “ for volume manufacturers to secure their supply chain and protect it from undisclosed synthetics.” Opsydia’s tech can add an alphanumeric sequence, coded shape or logo placed beneath diamonds that are just 0.5 millimeters in diameter. The goal is “to create a physical link to a supply chain record or branded jewelry origin.”
