"Jony Ive's latest design is the ultimate diamond ring –
made only of diamond":
Creating a ring-shaped diamond is no small feat; the diamond block will
be faceted with several thousand facets, some of which are as small as
several hundred micrometers. The interior ring will be cylindrically cut
out for the desired smoothness using a micrometer thick water jet
inside which a laser beam is cast. The finished ring will have between
2000-3000 facets which has never been seen before on a single piece.
