(IDEX Online) - A diamond tech company is introducing laser inscriptions below the stone's surface, to deter fraud.That means the unique identifier can't be removed without dramatically altering the stone.US-based PhotoScribe Technologies says the subsurface technology it's using was developed some years ago but was "a solution looking for a problem".Its newly-launched PermaScribe product can apply an inscription within any area of the faceted diamond - either visible or invisible under 10x loupe."The recent emergence of synthetic diamonds and a growing concern about counterfeiting have spurred an increase in demand for a solution (to tracking diamonds)," said the company in a press release."For the lab-grown diamond industry, there's a need for visible subsurface permanent identification that can be seen through a 10x loupe."Pic courtesy PhotoScribe Technologies
