The (RED) Diamond Ring was designed by Sir Jony Ive and Marc Newson and created exclusively for the (RED) Charity Auction by the Diamond Foundry. The ring will be made to fit the buyer (up to a size 5, which is quite small). Creating a ring-shaped diamond is no small feat; the diamond block will be faceted several thousand times, 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 with laser beam. The finished ring will have between 2000–3000 facets, more than has ever been seen before on a single piece. The Sotheby's auction takes place on December 5th. The ring is expected to fetch between $150k and $250k #onlineauction #sothebys #REDauction #alldiamondring #sirjonyive #marcnewson #diamondfoundry #reddiamondring #charityauction #diamonds #luxury https://www.instagram.com/p/BqgIMeJhY9j/?utm_source=ig_tumblr_share&igshid=11fzjyn10eu4g
