Auction house Bonhams Fine Jewellery said a 5.03-carat square-cut fancy pink diamond of VS1 clarity, which sold in London on September 26 for $2,935,263, fetched the most on its top-ten list of fine gem and jewellery lots sold in 2018. The stone set a new per carat auction world record for a fancy pink diamond, at $583,551 per carat.
Bonhams Global Director of Jewellery Jean Ghika commented, “The market has remained strong for exceptional pieces of jewellery from famed eras and world class makers. We’ve also seen excellent prices achieved for emeralds this year and anticipate that they will continue to follow an upward trajectory.”
She added, “Fancy coloured diamonds with intense colour saturations and of a good size also performed extremely well in all our fine jewellery sales in New York, London and Hong Kong and continue to be highly desirable to discerning collectors.”
She went on to say, “And finally, white diamonds, especially those over 10 carats, caught the eyes of global buyers, attracting competitive bidding from buyers around the world. These results combined with increased hammer sales and our market share growing globally concludes another very successful year for Bonhams Fine Jewellery.”
Looking to 2019, Ghika observed, “We anticipate that 2019 is going to be a year of colour with best in class emeralds on the up, rubies retaining their position as the king of gemstones, and Kashmir sapphires continuing to attract attention. The meteoric rise of fancy coloured diamonds looks set to continue given the global appetite for prized specimens.”
