This year was particularly intriguing as we saw many collections from prominent individuals go up for sale, including the Dodo Hamilton Collection at Freeman’s, which included a 16.56 carat emerald-cut diamond, which sold for $802,000. Another lot of note is the Farnese blue diamond, which was given to Elizabeth Farnese (daughter of the Duke of Parma) as a wedding gift in 1715. This diamond was passed down through royal families all throughout Europe. Sotheby’s sold the diamond in their Geneva Magnificent Jewels auction for $6.7 million, which exceeded the pre-sale estimate of $3.6 million – $5.2 million. Christie’s New York had an auction on June 12th where many pieces from the Rockefeller collection were sold, including 2 bracelets by Jean Schlumberger that both more than tripled their estimates.
