Sri Lanka Unveils World’s Largest Documented Purple Star Sapphire
3,563-carat ‘Star of Pure Land’ features rare six-ray asterism; valuations reportedly reach up to $400 million.
Sri Lanka has officially unveiled what is believed to be the largest documented natural purple star sapphire ever discovered. Weighing an extraordinary 3,563 carats, the gemstone—named “The Star of Pure Land”—was formally presented at a ceremony in Colombo by its anonymous owners, who confirmed that the stone is available for sale.
The sapphire is distinguished by its exceptionally sharp six-ray asterism, a rare optical phenomenon created by light interacting with microscopic inclusions within the gem. Displayed in a cabochon cut, the star effect appears vividly defined, placing the stone in an exceptional category among star sapphires.
Gemological experts note that while Sri Lanka is globally renowned for producing some of the world’s finest sapphires, this specimen stands apart in both scale and quality. Preliminary international valuations reportedly range between $300 million and $400 million, potentially making it one of the most valuable sapphires ever recorded.
Beyond its extraordinary market value, the discovery reinforces Sri Lanka’s historic significance in the global gemstone trade and highlights the enduring rarity of exceptional natural gemstones in an era increasingly shaped by laboratory-grown alternatives.
