I am peering through a jeweller’s eyeglass, looking for the BBC logo that has been inscribed inside a small diamond.
The inscription has been made using unique technology developed by Oxford-based Opsydia.
Its machines are the only ones on the market that can penetrate the surface of a diamond and manipulate its atoms.
The logo I am trying to find is less than half a millimetre wide. Despite instruction from Lewis Fish, head of product at Opsydia, I can’t see it.
“It is very difficult,” he says. “They’re intentionally very fine, and it is really trained jewellers they are aimed at.”
But why would anyone want to write on the inside of a diamond?
