Important diamonds sold at Sotheby’s recently

Loose Diamonds Sydney

There are not many Fancy Vivid Yellow diamonds of over 30 carats, in existence, so it was hardly surprising that the 30.16 carat, VS1 clarity stone in Sotheby’s October auction in Hong Kong sold for US$2.8 million.

In the same sale, a 5.01 carat Fancy Vivid Purplish Pink went for a comparatively reasonable US$5.5 million, probably because it only had a half certificate and its clarity rating was not disclosed.

The Farnese Blue

But provenance, not size, has been the defining characteristic of 2018 auctions, although there has also been tremendous enthusiasm for fresh-to-market jewels from private collections. Fancy blue diamonds were the best performers in the regularly scheduled auctions, and the most significant blue diamond of the year was the 6.16 carat Farnese Blue, which sold for US$6.7 million at the Sotheby’s Geneva May 16 auction, nearly doubling its pre-sale estimate. The diamond, graded Fancy Dark grey-blue by the GIA, was from the Golconda Mine in India (now Hyderabad) and was given to Elisabeth Farnese, daughter of the Duke of Parma, in 1715 when she married Philippe V of Spain. The diamond stayed in the family for seven generations, going from Spain to France, Italy and Austria before being sold this year.

Since last summer, Sotheby’s has held online auctions of loose diamonds supplied by Diacore, whose CTF Pink Star holds the world auction record for precious gems.

Elizabeth Taylor said “Big girls need big diamonds.”

But Sotheby’s Diamonds’ most exceptional gem has been a 102.34-carat, D-Flawless, Type IIA round brilliant cut diamond, which the auction house describes as “the rarest and most valuable white diamond ever to come to market”. It took diamond cutters in Johannesburg and New York over six months to cut the gem from a 425-carat rough mined by the De Beers group in Botswana. Only seven D-colour diamonds weighing more than 100 carats have ever appeared at auction, and none of them have been round brilliant cuts. The yield from a rough stone is usually maximized with a pear or emerald-cut.
