Christie’s featured the most expensive lot the house had ever auctioned off in a digital sale, a rare 28.86-carat D-Colour, VVS1 clarity, Type 11a diamond, set on a platinum ring. The estimate was $1-2 million but after 31 competitive bids from Asia to America, the diamond fetched a staggering $2,1 million - the highest price ever achieved during an online auction.
The emerald-cut stone is one of the rarest. The ‘D’ signifies its clarity, the diamond is formed of pure carbon with no impurities making it completely colourless and thus making this one of the most coveted diamonds of all time. According to The Telegraph, there are less than two percent of Type 11a diamonds in the world and ahead of the sale, Christie’s called the stone, a ‘miraculous phenomenon.’
