Discover the Star of Pure Land: the world’s largest purple star sapphire at 3,563 carats, worth $300-400M. Found in Sri Lanka, this rare gem rewrites history.
A Discovery That Shook the Gem World
In the heart of Sri Lanka’s gem capital, a discovery has emerged that is set to rewrite gemological history. On Saturday, January 17, 2026, the owners unveiled a massive purple star sapphire weighing 3,563 carats, naming it the “Star of Pure Land.” Consultant gemologist Ashan Amarasinghe confirmed it as the world’s largest documented natural purple star sapphire, a designation that places this gemstone in a league of its own among the planet’s most extraordinary natural treasures.
The Star of Pure Land represents more than just impressive numbers. This gemstone embodies the culmination of millions of years of geological processes, traditional mining heritage, and the enduring reputation of Sri Lanka as the world’s premier sapphire source. With an estimated value between $300 million to $400 million, this discovery has sent ripples through the international gem market and scientific community alike.
The Magic Behind the Star: Understanding Asterism
What makes the Star of Pure Land truly mesmerizing is not just its size but the optical phenomenon it displays. The gem shows a well-defined asterism with six rays, a feature that transforms this already remarkable stone into something truly magical.
Asterism, derived from the Greek word for “star,” creates a captivating visual effect where a star-shaped pattern appears to float beneath the gemstone’s surface. This effect is generated by reflections of light from extremely fine needle-shaped inclusions within the stone’s crystal structure. In sapphires and rubies, these stars are caused by titanium dioxide impurities called rutile present within the gem.
Think of it like this: imagine thousands of microscopic needles arranged in perfect geometric patterns inside the sapphire. When light hits these needle-like inclusions, it bounces back in specific directions, creating the appearance of a glowing star. The natural symmetry of corundum (the mineral family of sapphire and ruby) has a trigonal crystal system, which favors three-directional rutile growth, hence the six-ray stars in these stones.
The six rays you see radiating from the center of the Star of Pure Land are not painted or carved. They emerge naturally from within the gem itself, moving and shimmering as the stone or light source shifts position. This dancing star effect has captivated humanity for centuries, inspiring ancient legends and modern scientific inquiry alike.
From Earth to Discovery: The Journey of the Star of Pure Land
The story of how this extraordinary gemstone came to light reads like a treasure hunter’s dream. One of the owners revealed that the gem was found in a gem pit near the remote Sri Lankan town of Rathnapura, known as the “city of gems,” in 2023.
Rathnapura, whose name literally translates to “City of Gems” in Sinhala, has been the beating heart of Sri Lanka’s gemstone industry for over two thousand years. Mining of gems in Sri Lanka goes back to at least 2,000 years, with the island nation earning the poetic name “Ratna Deepa” or “Island of Gems” in ancient times.
The mining methods used in Rathnapura remain remarkably traditional. Gem mining in Sri Lanka is primarily from alluvial secondary deposits found in gem-bearing river gravels (illam), in ancient flood plains and streams that are now covered with productive farm land and terraced rice paddies. To reach the gem-bearing layers, 5 to 50 foot deep mining pits are hand-dug by teams of several workers, pumping out any groundwater as it enters the hole from below.
Picture teams of skilled miners working in humid conditions, carefully excavating deep pits by hand, tunnel by tunnel. When the pit is dug to the correct depth, tunnels are dug horizontally in several directions to minimize surface degradation. The gem-bearing gravel, called “illam,” is then extracted and sifted using traditional conical baskets in a process that has remained largely unchanged for centuries.
The Star of Pure Land likely spent months or even years in someone’s collection before its true significance was recognized. The anonymous owners secured the gem alongside others in 2023, only later realizing its unparalleled significance. Imagine their astonishment when gemological testing revealed they possessed not just a large sapphire, but the largest purple star sapphire ever documented.
Scientific Verification: Establishing World Record Status
For a gemstone to claim world record status, rigorous scientific documentation is essential. The Star of Pure Land underwent extensive testing and certification by multiple prestigious institutions.
The gemstone has been certified by the Gemological Institute of America (GIA) and independently documented by the Lanka Gemological Laboratory, which confirmed its Sri Lankan, or Ceylon, origin. These certifications are crucial because they verify the stone’s natural origin, confirm it has not been artificially created or heavily treated, and establish its authenticity for the permanent scientific record.
The certification process involves sophisticated testing using specialized equipment. Gemologists examine the stone under powerful microscopes, test its optical properties, analyze its chemical composition, and document its unique characteristics. For the Star of Pure Land, experts noted that its round cabochon cut, combined with its size, clarity and color, makes it the largest known round-cut natural purple star sapphire ever recorded.
A cabochon cut is a specific way of shaping gemstones with a smooth, rounded, dome-like surface without facets. This cutting style is essential for displaying asterism because the curved surface acts like a lens, focusing light and making the star effect visible. Cutting a cabochon from rough stone requires exceptional skill, as the cutter must precisely orient the stone to ensure the star appears centered and well-defined.
The Rarity Factor: Why This Discovery Is So Extraordinary
To truly appreciate the Star of Pure Land, we need to understand just how rare natural purple star sapphires are, especially at this scale.
First, consider size. At 3,563 carats (approximately 712.6 grams or 1.57 pounds), this gemstone is extraordinarily massive. Most sapphires used in jewelry weigh between 1 to 5 carats. Finding a natural sapphire over 100 carats is already exceptionally rare. A sapphire exceeding 3,500 carats is virtually unheard of.
Second, the purple color adds another layer of rarity. While blue sapphires are the most famous, sapphires actually occur in nearly every color of the rainbow. Purple sapphires occupy a special position in the color spectrum, often exhibiting a mesmerizing blend of red and blue hues. The specific purple shade of the Star of Pure Land, combined with its size, makes it unique in the world.
Third, the asterism itself is a rare occurrence. Asterism is generated by reflections of light from extremely fine needle-shaped inclusions within the stone’s crystal structure. For a star to be well-defined and centered requires precise natural conditions during the gem’s formation. Experts said the sapphire was formed through natural geological processes over millions of years and cannot be replicated or artificially engineered, describing the conditions required to produce such a specimen as extremely rare.
Ratnapura is the source of some of the priceless gemstones in the world, including the Blue Giant of Orient (466 carats), Logan Blue Sapphire (423 carats), Blue Belle of Asia (400 carats), and the Star of Lanka (393 carats). The Star of Pure Land now joins this illustrious list, surpassing all previous records for purple star sapphires.
Sri Lanka: The Island of Gems
Sri Lanka’s reputation as a gemstone paradise is well-earned. The island’s unique geological history has created perfect conditions for gem formation.
Situated within Sri Lanka’s ancient metamorphic rock formations, this area has provided the ideal conditions for gem formation over billions of years. Over 90% of the country’s landmass consists of high-grade metamorphic rock, dating back 3-4 billion years. These ancient rocks, subjected to intense heat and pressure over geological time, have yielded an astonishing variety of gemstones.
Ceylon sapphires, as sapphires from Sri Lanka are traditionally known, have graced royal crowns, religious artifacts, and museum collections for millennia. The Mahavamsa, the ancient chronicle of Sri Lanka, mentioned gems and jewelry on several occasions, demonstrating that the island’s gem trade has deep historical roots.
The gem fields of Sri Lanka extend beyond Rathnapura. Significant gem-mines throughout Sri Lanka include the Bibile sapphire mines (central), Elehara Gem Fields (near Ratnapura), Metiyagoda moonstone mines (south-west coastal), Morawaka (south-central), Nuwara Eliya mines (mountainous tea plantation area), and Pelmadulla sapphire mines. Each region produces gems with distinct characteristics, contributing to Ceylon’s reputation for diversity and quality.
What sets Sri Lankan gem mining apart is its commitment to environmental stewardship. The government sees to it that the land is not spoiled by mining operations, through strict regulation of low-impact mining procedures. This approach ensures that gem mining can continue for future generations while preserving the island’s lush agricultural lands and natural beauty.
The Cultural and Historical Significance
Beyond its scientific and monetary value, the gemstone was presented as an object of cultural and historical significance. The Star of Pure Land represents a tangible connection between Sri Lanka’s geological past and its cultural present.

The Science of Sapphire Formation
Understanding how the Star of Pure Land formed requires us to think in terms of geological time spans that dwarf human experience.
Sapphires are a variety of the mineral corundum, composed primarily of aluminum oxide. The purple color in this sapphire comes from trace amounts of chromium and iron present during the crystal’s formation. The presence and concentration of these trace elements, combined with specific temperature and pressure conditions, determined the exact purple hue we see today.
The rutile inclusions responsible for the asterism formed through a process called exsolution. As the sapphire crystal cooled over millions of years, dissolved titanium oxide began to precipitate out of the solution, forming microscopic needle-like crystals. These needles aligned themselves along the crystal structure of the host sapphire in three distinct directions, creating the perfect geometry for a six-ray star.
The round cabochon shape maximizes the visibility of this star effect. When light enters the stone from above, it reflects off these countless microscopic rutile needles, concentrating along six specific directions and creating the star pattern we observe.
Impact on the Gem Market and Scientific Community
The unveiling of the Star of Pure Land has significant implications for both the commercial gem market and the scientific community.
For the gem market, this discovery reaffirms Sri Lanka’s position as the world’s premier source for exceptional sapphires. It may stimulate renewed interest in purple sapphires specifically and could influence market values for large, natural star sapphires globally.
For gemologists and mineralogists, the Star of Pure Land provides an opportunity to study asterism and sapphire formation at an unprecedented scale. The gem’s size allows for detailed examination of its internal structure, potentially revealing new insights into how such large, well-formed crystals develop in nature.
The estimated value of $300-400 million reflects not just the gem’s size and quality, but also its uniqueness. There is only one largest purple star sapphire in the world, and the Star of Pure Land now holds that title definitively.
Comparing to Other Famous Sapphires
To put the Star of Pure Land in context, let’s compare it to other legendary sapphires:
The Star of India, perhaps the most famous star sapphire in the world, weighs 563 carats and is housed at the American Museum of Natural History in New York. The Star of Pure Land weighs more than six times as much.
The Star of Lanka, proudly owned by the National Gem and Jewelry Authority of Sri Lanka, weighs 393 carats. Again, the Star of Pure Land is nearly nine times larger.
The Blue Belle of Asia, a remarkable 400-carat cushion-cut sapphire, sold for approximately $17 million in 2014. While that sapphire lacks asterism, it demonstrates the tremendous value placed on exceptional large sapphires.
The Star of Pure Land’s combination of extreme size, natural asterism, purple color, and round cabochon cut makes it genuinely unique in the pantheon of great sapphires.
The Traditional Art of Gem Cutting
Creating a well-cut cabochon from a large rough sapphire crystal requires extraordinary skill and experience. The cutter who shaped the Star of Pure Land faced numerous challenges and critical decisions.
First, the rough stone had to be carefully examined to determine the optimal orientation. The cutter needed to position the stone so that the star would appear centered on the finished cabochon’s dome. This requires understanding the internal structure of the crystal and predicting how light will interact with the rutile inclusions.
Second, the cutter had to decide how much material to remove to achieve the ideal shape while preserving as much weight as possible. Every carat matters in a gemstone of this value, yet the shape must be symmetrical and pleasing.
Third, the polishing process requires patience and precision. The cabochon’s surface must be perfectly smooth to allow the star to display clearly. Any irregularities in the surface could distort or weaken the asterism.
The result is a masterpiece of lapidary art, a testament to traditional Sri Lankan gem-cutting expertise passed down through generations.
Why Purple? The Science of Sapphire Color
While blue is the most recognized sapphire color, corundum crystals can display nearly every color depending on which trace elements are present during formation.
Purple sapphires derive their color from a combination of chromium (which typically creates red in rubies) and iron (which contributes to blue). The specific ratio of these elements, combined with the crystal’s formation conditions, determines whether the resulting color is more violet, more purple, or somewhere in between.
The purple of the Star of Pure Land represents a delicate balance achieved naturally over millions of years. This color cannot be exactly replicated in a laboratory because the natural conditions that created it were unique to that specific location and moment in geological time.
Conservation and Preservation Considerations
As discussions continue about the Star of Pure Land’s ultimate destination, conservation becomes an important consideration. Gemstones of this significance require special care and protection.
Storage conditions must maintain stable temperature and humidity to prevent any potential stress on the crystal structure. Security measures are essential given the gem’s immense value. Documentation must be carefully preserved to ensure the gemstone’s story and scientific data remain accessible to future generations.
Many experts hope that the Star of Pure Land will eventually find a home in a major museum or institutional collection where it can be studied, appreciated, and protected for perpetuity. Such placement would allow the public to experience this natural wonder while ensuring its preservation.
The Human Element: Lives Touched by Gemstones
Behind the Star of Pure Land’s story are countless human lives connected to Sri Lanka’s gem industry. The miners who excavate deep pits by hand, the gem dealers who evaluate rough stones, the cutters who transform rough crystals into polished gems, and the families whose livelihoods depend on this ancient trade.
The gem industry provides employment and income for thousands of Sri Lankan families, particularly in regions like Rathnapura where few other economic opportunities exist.
