Why is a Kashmir sapphire worth 10 times more than a top-quality Ceylon? Watch Sotheby's Jewellery Specialist Jane Ki dive into the world of high-gemology to compare the two most famous sources of blue sapphires on earth. From the geologically extinct mines 15,000 feet high in the Himalayas to the "Royal Blue" riverbeds of Sri Lanka, we discover the reason behind the glow that makes Kashmir stones the crown jewels of any collection. Both sapphires are offered in the upcoming Hong Kong High Jewelry Sale on 23 April, 2026.
The Hong Kong Luxury Week is presented by Standard Chartered Priority Private.
