Heritage Auctions brings rare emeralds to Hong Kong debut sale

Heritage Auctions put untreated Colombian emeralds and a platinum Rolex Day-Date at the center of its first combined jewelry-and-timepieces sale in Hong Kong, a clear bid to see whether the city’s collectors will trade comfortably across categories when rarity and signature matter most. The Fine Jewelry & Timepieces Signature Auction took place June 15, with a public preview on June 14, and it arrived as Heritage pushed deeper into Asia’s luxury market.

The headline jewel was a Repossi platinum ring centered on a 3.11-carat untreated Colombian emerald, carrying a $90,000 reserve. Heritage also offered a larger 4.72-carat untreated Colombian emerald in a platinum ring with two baguette diamonds and a $42,000 reserve. Jill Burgum, Heritage’s executive director of fine jewelry, said it is “extremely rare” to encounter a Colombian emerald with no treatment, and that scarcity is exactly what gives the category its pull in Hong Kong: collectors there have shown they will pay for color, origin and transparency when the stone is exceptional.

That same appetite extended to the rest of the catalog. A necklace set with 14.33 carats total weight of padparadscha sapphires and 2.72 carats total weight of full-cut diamonds underscored the market’s growing taste for nuanced colored stones, not just headline-size gems. Heritage also brought a 10.50-carat Burma sapphire ring, an unmounted 3.01-carat fancy vivid yellow diamond with a $70,000 reserve, and a diamond ring with a 4.05-carat square-shaped center stone and nearly 3 carats of triangular and baguette-cut diamonds. The strongest vintage lesson here is simple: in Asia, saturation of color and clarity of design still win, especially when the setting is platinum and the stones are untreated or unusually documented.

The watches sharpened the message. Heritage’s top lot was a platinum Rolex Day-Date reference 228396TBR with an ice blue dial, baguette-cut diamond hour indexes, a 40 mm case and a 70-hour power reserve. De Bethune and Harry Winston rounded out the cross-category offering, and that mix suggested a buyer profile willing to move from signed jewelry to jewel-like horology without changing aesthetic language. Heritage said the Hong Kong sale was part of a broader expansion in Asia, building on auctions in Asian art, coins, currency, pop culture and wine.

That strategy makes sense against Hong Kong’s recent results, including a Kashmir sapphire necklace that set a new Asia auction benchmark at more than HK$125 million. If the market response mirrors that energy, the categories most likely to gain traction are signed platinum jewelry from houses such as Repossi and Harry Winston, untreated Colombian emeralds, padparadscha and Burma sapphires, and gem-set watches that read as serious jewelry first and timepiece second.
