Diamonds still are a girls best friend at least at the spring auctions.

Christie’s sold the GIA-graded 14.62 ct. Fancy Vivid blue Oppenheimer Blue diamond in Geneva on May 18 – the largest Fancy Vivid blue ever to come up for sale. Not to be outdone, Sotheby’s Geneva sold the 15.38 ct. GIA-graded Fancy Vivid pink Unique Pink diamond, the largest diamond of that grade ever to go under the hammer. The $31.6 million price came in at the lower end of the pre-sale estimate for the diamond mined in the old Kimberley deposits in South Africa. A 5.09 ct. GIA-graded Fancy Vivid green diamond will provide the finale for the 2016 spring season. The diamond, tracked from rough to rectangle cut and mounted in a ring surrounded by Fancy pink melee, is expected to sell for $16 to $20 million.
