The world’s largest flawless vivid blue diamond will go under the hammer by Christie’s Geneva next month. Dubbed ‘The Blue’ because of its magnificent colour, the diamond is expected to fetch between $21 – 25 million. A shimmering pear-shaped rock the colour of cobalt and weighing 13.22 carats, this privately-owned diamond is a “sensational stone,” the auction house said, adding that the seller wanted to remain anonymous. Christie’s auction next month, scheduled for May 14 would comprise 250 pieces at a joint estimated value of $80 million.
The sale will also feature a 5.5-carat vivid blue-green diamond named “The Ocean Dream“, estimated to be worth up to $9.5 million. The combination of its size, natural origin, hue, and saturated colour makes it an extremely unusual occurrence.
Among other notable gemstones will be a 76.51-carat pink diamond set as a necklace valued at up to $10 million, and a 75.97-carat flawless colourless diamond estimated to be worth up to $15.5 million.
Just six months earlier, Christie’s Geneva sold the world’s largest orange diamond, a 14.82-carat gem called “The Orange”, which went for $35.5 million despite its $17-20 million price tag.
