All-diamond ring
An entire ring cut from a single diamond, created by Apple’s chief design officer Jony Ive and industrial designer Marc Newson, went under the hammer for $256,000 in December. The item has between 2,000 and 3,000 facets, a number never previously seen in a single-diamond piece, according to auction house Sotheby’s. The ring was auctioned off in Miami, with the proceeds donated to (RED), an HIV/AIDS charity set up by singer Bono and activist Bobby Shriver.
