World of Colors at the Sotheby’s Hong Kong Auctions

If you’ve been following recent color diamond and gemstone sales, you’ve likely captured a few intriguing developments. First of all, there’s a lively dynamism swirling around fancy color diamonds and gemstones right now. It’s nothing for the gavel to come down in the double-digit-million dollar range for these bright beauties.

Of course, many stones have splendid carat sizes that offer plenty of viewing opportunities to admire their color. But interestingly too. is the fact that not all the pricey stones are huge.




Size doesn’t always matter

With the cognoscenti---quality trumps size every time. Serious collectors know this and respond with their money to discovering a high-value stone that may never come around again. The well-worn phrase ‘money talks’ is clearly at work.

Large or smaller sized gemstones at auction look like a lively artist’s palette lately. Each vivid hue is getting some love these days. Yellow—green—blue--red and more are making a splash across the auction block, as collectors eagerly snatch them up. 


The way I see it

My own observations are these; the market has shown remarkable energy for colors, and prices are holding up fairly well in gemstones. Also the few top-tier fancy color diamonds have made strong prices too. You can see well-designed rings---even those with relatively small center stones like the Bulgari emerald and diamond ring sold at Sotheby’s Hong Kong shown below. This fetched a full 50% over the pre-sale estimate at $60,000 US. 

A Bulgari Emerald ring Set with an octagonal step-cut emerald weighing 1.56 carats Columbian Emerald flanked by a pair of square emerald-cut diamonds weighing 1.54 and 1.50 carats, respectively, mounted in platinum, signed Bulgari, size 5 ¾.

All in all, gemstones and fancy color diamonds are holding strong, and their market share is growing. Take a look at this rainbow of brightly colored stones, each one is important for its species. 





Beauty is Priceless 

Beauty is the main event when it comes to colored gems. I like to say that beauty is priceless, especially if it’s a rare gem.  Because truthfully, what price can you put on an original treasure that will never be duplicated?

We at Leibish experience a strong demand for fancy intense and fancy vivid yellow diamond rings.





All of these breathtaking stones are memorable of course. But, for me, the most remarkable sale from that Sotheby’s Hong Kong sale in October 2023 was the “Infinite Blue”. This fancy vivid blue stone can track its provenance back to the Petra Diamonds iconic Cullinan Mine. That’s a stellar lineage for anyone’s money. It’s notable that not many blue diamonds over 10 carats have ever hit the auction block.
