Said to be the most expensive piece of jewellery in the world, it was sold for a staggering price of $46 million in November 2010. Famously known as the Graff Pink, it is classified as a type-II colour diamond, and has a perfect rating and price of about $1.85 million per carat. This rare, 24.78-carat pink diamond was once owned by American celebrity jeweller Harry Winston, and is described as “one of the greatest diamonds ever discovered”. The diamond, mounted in a ring, was sold by Sotheby’s auctioneers in Geneva in November 2010. Before its sale, the stone was expected to enter the ten most expensive diamonds in the world. Upon selling for $46 million (£29 million), it became the most expensive single jewel ever sold at auction at that time.
This ring features a triangular colourless diamond of 9.87 carats, paired with a stunning, triangular blue diamond of 10.95 carats – the largest fancy vivid blue diamond of this cut ever to be offered on auction. Fancy vivid blue diamonds of this size are among the rarest of coloured diamonds – only one in about 10 million will possess a colour pure enough to qualify as such. The ring is priced on request for prospective bidders, but is expected to achieve in excess of $12 million.
Wizard of Oz Ruby Slippers
Almost everyone is familiar with Metro Goldwyn Mayer’s The Wizard of Oz, among the most memorable films in history. In it, the character Dorothy wears the splendid-looking, magical ruby shoes, which she only needed to tap together to get to a certain place, as she journeyed to find the Wizard of Oz. Fifty years after the production of that movie, in order to celebrate its golden anniversary, those ruby shoes were recreated by Ronald Winston. Rather than using sequins, however, Winston refashioned the ruby shoes with 1,350 carats worth of authentic rubies. All in all, there were about 50 carats of diamonds and 4,600 rubies in the footwear. Valued at $3 million, the said shoes truly deserve to be called the most expensive in the world.
