Jean Ghika, Global Director of Jewelry, Bonhams, comments: "The market has remained strong for exceptional pieces of jewelry 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.

"Fancy colored diamonds with intense color saturations and of a good size also performed extremely well in all our Fine Jewelry sales in New York, London and Hong Kong and continue to be highly desirable to discerning collectors. 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 Jewelry."


Jean Ghika added: "We anticipate that 2019 is going to be a year of color 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 colored diamonds looks set to continue given the global appetite for prized specimens."
