‘The Regent Kashmir’ and ‘The Regal Ruby’ to Share Spotlight at Christie’s HK

“The Regent Kashmir” and “The Regal Ruby” are set to share the spotlight at Christie’s Magnificent Jewels live auction in Hong Kong on May 27. Representing the pinnacle of beauty and quality, the 35.09-carat Kashmir sapphire and 13.22-carat Burmese ruby are true rarities.

Christie’s classified The Regent Kashmir as a “once-in-a-generation masterpiece” and the most valuable piece of Kashmir sapphire jewelry offered at Christie’s globally in the past five years. Set in a ring, the sapphire is expected to fetch between $8.3 million and $12.2 million.

The Regal Ruby is poised to become the most valuable and largest Burmese ruby sold at Christie’s Hong Kong in a decade. Also set in a ring, the ruby carries a pre-sale estimate of $6.4 million to $10.2 million.

First discovered in the Zanskar mountain range of Kashmir, India, in 1881, sapphires from this region are famous for their intense “cornflower” or velvety blue hue and are considered the finest in the world.

Burmese rubies from the Mogok Valley in Myanmar (formerly Burma) are renowned for their richly saturated red color known as “pigeon’s blood.” Top-quality unheated rubies exceeding 5 carats are remarkably rare.

Despite the eight-figure price estimates for the headliner gems, it’s likely that the current sapphire and ruby record holders will retain their honors.

The most expensive ruby ever sold at auction was the “Estrela de Fura,” a 55.22-carat gem, which fetched $34.8 million at Sotheby’s in New York in June 2023. The record for the priciest sapphire to go under the hammer is held by the “Blue Belle of Asia,” a 392.52-carat cushion-cut Ceylon sapphire, which earned $17.3 million at Christie’s Geneva in November 2014.

Other highlights from Christie’s Magnificent Jewels auction in Hong Kong include a 10.35-carat Colombian emerald and diamond ring (estimate: $870,000 – $1.2 million) and a pair of Colombian emerald and diamond earrings (estimate: $700,000 – $960,000). The emeralds featured in the earrings weigh 7.03 carats and 6.92 carats, respectively.

The auction will take place on May 27 during Hong Kong Luxury Week at Christie’s Asia Pacific headquarters at The Henderson, a 36-story state-of-the-art office tower that opened in 2024. The featured jewelry will be exhibited in Taipei, Bangkok, Geneva, Beijing and Shanghai before returning to Hong Kong for the sale.
