💎 1. What is a Star Sapphire?
A star sapphire is a special type of sapphire (a precious gemstone made from corundum) that displays a star-like optical effect known as asterism.
• The “star” you see is created by needle-like inclusions (usually rutile) arranged in intersecting directions within the stone.
• When light strikes the surface just right, it reflects as a sharp star pattern, often featuring six rays. This effect is quite rare, significantly enhancing the gem’s beauty and value.
🌍 2. Sri Lanka’s Gem Heritage
Sri Lanka, especially the Ratnapura area (literally the “City of Gems”), is famous for high-quality sapphires, including various star sapphires in colors like blue, black, purple, and more.
💥 3. The Recent “Star of Pure Land” Find
In early January 2026, Sri Lanka revealed a massive purple star sapphire thought to be the largest of its kind ever documented:
• Weight: ~3,563 carats (huge for a gemstone).
• Name: “Star of Pure Land”.
• Color: Purple (rare for star sapphires).
• Asterism: Distinct six-rayed star.
• Value: Estimated between $300 million and $400 million by international valuers.
• Discovered in 2023 near Rathnapura and identified later for its exceptional quality.
• It has been polished and is being showcased, while the owners remain anonymous.
This gemstone has attracted worldwide attention due to its size, quality, and the scarcity of purple star sapphires.
🧠 4. Why Such Sapphires Are Valuable
Several factors contribute to the value of star sapphires:
🔹 Asterism quality: Clear, centered stars are the most sought after.
🔹 Size: Larger stones (especially those with hundreds or thousands of carats) are extremely rare.
🔹 Color: Strong, rich hues (especially rare ones like purple) enhance desirability.
🔹 Transparency & clarity: Although star sapphires are typically opaque to translucent, better clarity increases value.
🔹 Origin & certification: Stones from Sri Lanka with official gemological certification (like GIA or other labs) tend to command higher prices.
