Christie’s in Hong Kong has auctioned off a 101.27-carat diamond. That is the size of a ping-pong ball people, that is a freaking huge diamond. It is the largest colorless stone to be auctioned in Asia, and it sold for $6,200,000.

According to Reuters, “The gem, which is internally flawless but rated VVS1 (very very slightly imperfect 1st degree) for clarity was sold after patchy bidding for HK$48.5 million including the buyer’s premium, a relatively low per-carat price and at the low-end of its pre-sale estimate.”

While rare polished diamonds achieved all-time highs per carat at sales in Geneva late last year, a much-hyped 72.22 carat “D” flawless white diamond failed to sell at a Sotheby’s Hong Kong auction in April, suggesting demand for top stones may be waning due to a weakening world economy.

Higher prices on diamond sales were achieved last year at sales in Geneva. This year however prices seem to have fallen due to a weakening world economy, while some fail to sell at all. Just this April for example, a “much-hyped” 72.22-carat flawless diamond failed to sell at a Hong Kong Sotheby’s auction.
