Apple design chief Jony Ive, whose innovations include the iPod, iMac, MacBook Air, iPhone and iPad, has designed a special ring in conjunction with industrial designer Marc Newson exclusively for (RED) by Diamond Foundry. Auction house Sotheby’s unveiled the one-of-kind-piece and announced the sale of the ring will help raise funds to help eliminate HIV/AIDS in eight African countries.

In terms of its design, the diamond ring takes cues from the unibody design of a MacBook, which is created out of a solid piece of aluminum, as the diamond ring is cut out of a single diamond block. Some of its facets measure as small as several hundred micrometers.

Additionally, Sotheby's points out that the interior portion of the ring will be cut and smoothened using a micrometer thick water jet with a laser beam. The finished piece will then have "between 2000-3000 facets which has never been seen before on a single piece."

This bespoke ring will be made to fit the buyer up to a size five, and the estimated sale price is suggested to fetch $150,000 to $250,000. The auction begins on December 8 and for more details, click the bar below.
