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.

Botswana Looks Beyond Rough Diamond Sales, Eyes U.S. Jewelry Market
The Duty Exemption By US Presents An Opportunity For Domestic Jewelry Manufacturers In Gaborone To Bypass Traditional Middle-Market Hubs and Establish A Direct Pipeline To American Consumers
Grappling with a painful downturn in global rough-diamond demand, Botswana is pivoting its economic strategy: expanding up the supply chain directly into American retail shelves while leveraging its resource wealth to fund conservation and diversification.
Speaking on the sidelines of New York Climate Week, Bogolo Joy Kenewendo, Botswana’s Minister of Minerals and Energy, highlighted the southern African nation’s plan to capitalize on a 0% import-tariff rate to the U.S. market. The duty exemption presents an opportunity for domestic jewelry manufacturers in Gaborone to bypass traditional middle-market hubs and establish a direct pipeline to American consumers.
shift The push into value-added manufacturing comes as the world’s top diamond producer by value navigates a broader structural Diamond revenues have long formed the bedrock of Botswana’s post-independence balance sheet, underwriting universal secondary education and tuition-free university funding. However, recent market volatility has underscored the vulnerabilities of a mono-sectoral economy.
Under the Botswana Economic Transformation Programme (BETP)—an initiative spearheaded directly by President Duma Boko and his vice president—the government is directing resources toward manufacturing, agriculture, and broader mining sectors to reduce its heavy reliance on rough diamond sales.
To support its luxury exports, Botswana is recalibrating its brand narrative around origin, environmental stewardship, and social impact. The country recently announced a five-year extension of the “Okavango Eternal” partnership alongside De Beers Group and the National Geographic Society. The initiative aims to protect the ecological integrity of the Okavango River Basin while tying diamond purchases to conservation efforts.
With De Beers currently facing an impending ownership change, officials remain optimistic that any capital restructuring could bring additional funds into Botswana to accelerate its domestic economic transition.
