World’s Largest Purple Star Sapphire, teh “Star of Pure Land,” Revealed in Sri Lanka
COLOMBO, Sri Lanka — A colossal Purple Star Sapphire, weighing a staggering 3,563 carats and believed to be the largest of its kind globally, was unveiled on Saturday in Colombo, sri Lanka.The owners, identifying themselves as the Star of Pure Land Team, are seeking a buyer for this extraordinary gem, wiht estimates placing its value between $300 million and $400 million.
A Gemological Marvel: Introducing the “Star of Pure Land”
The remarkably round-shaped sapphire, aptly named “Star of Pure Land,” boasts a unique natural purple hue and a striking asterism – a star-like phenomenon caused by the presence of microscopic rutile needles within the gem. According to Ashan Amarasinghe, a consultant gemologist, this sapphire is the largest documented natural purple star sapphire in existence. “This is the largest purple star sapphire of its kind,” Amarasinghe stated, emphasizing the gem’s exceptional six-ray asterism, a quality setting it apart from other sapphires. Reuters provides further details on the unveiling event.
Understanding Asterism: The Starry Phenomenon
Asterism, the star-like effect seen in some gemstones, is a result of the Tyndall effect. This occurs when light interacts with tiny, needle-like inclusions – typically rutile – aligned in multiple directions within the stone. When light enters the gem,it’s scattered and reflected,creating a fleeting,star-shaped pattern. The number of rays in the asterism depends on the crystal structure of the gem and the alignment of the inclusions. A six-rayed asterism, as seen in the “Star of pure Land,” is most common in corundum, the mineral family that includes sapphires and rubies.
The Discovery and Certification Process
The gem’s journey began in 2023 when it was discovered in a gem pit near Rathnapura, a town in sri Lanka renowned as the “city of gems.” purchased alongside other rough stones, its extraordinary nature wasn’t immediately apparent. It took approximately two years for the owners to recognize the gem’s unique qualities. To confirm its authenticity and value, the sapphire underwent rigorous certification by two autonomous gemological laboratories, providing assurance of its exceptional characteristics.

Rathnapura, meaning “city of gems” in Sinhala, has a history steeped in gemstone mining dating back centuries. The region’s geological composition, formed by ancient volcanic activity, is conducive to the formation of a wide variety of gemstones, including sapphires, rubies, alexandrite, and cat’s eyes. Sri Lanka has long been celebrated for its high-quality gemstones, attracting traders and gemologists from around the world. The Gemological Institute of America (GIA) offers a deeper insight into the history and geology of Sri Lankan sapphires.
The Value of Sri Lankan Sapphires: Colour, Clarity, and shimmer
sri Lankan sapphires are globally prized for their distinctive beauty, encompassing a range of hues beyond the customary blue. These include the coveted Padparadscha sapphire—a delicate pinkish-orange variety—as well as vibrant yellows, greens, and the increasingly sought-after purple shades. The value of a sapphire is determined by several factors, often referred to as the “4Cs”:
- Color: The intensity and purity of the color significantly affect value.
- Clarity: Fewer inclusions generally mean a more valuable stone, though some inclusions, like those causing asterism, can enhance value.
- Cut: A well-executed cut maximizes brilliance and showcases the sapphire’s color.
- Carat Weight: Larger sapphires are typically more valuable, but price per carat increases exponentially with quality.
The “Star of Pure Land” distinguishes itself on all these counts: its rare purple color, defined asterism, and considerable carat weight contribute to its exceptional estimated value. International valuers have assessed the gem’s worth at between $300 million and $400 million,reflecting its unique combination of characteristics.
