Blue‑to‑Purple Phenomenon • Six‑Ray Asterism • Sri Lanka 🇱🇰 • Eye‑Clean
Unveiling a masterpiece of nature: a Natural, Unheated Color‑Change Star Sapphire of extraordinary beauty and rarity. At 7.01 carats, this gem stands in the elite class of collectible sapphires, exhibiting both dramatic color transformation and a perfectly centered six‑ray star that glides effortlessly across the surface under direct light.
This sapphire transitions between deep royal blue and regal violet‑purple, depending on the light source. The phenomenon is vivid, unmistakable, and highly prized among connoisseurs and collectors.
Under a single light source, a sharp, symmetrical six‑ray star emerges—clean, centered, and beautifully defined. This level of clarity and precision is exceptionally rare in natural star sapphires.
Unlike most star sapphires, which often contain heavy inclusions, this stone is best‑grade eye clean, allowing the body color and star effect to shine with remarkable purity and brilliance.
Sourced from the legendary gem fields of Sri Lanka, renowned for producing the world’s most coveted star sapphires. Ceylon origin adds prestige, value, and historical significance to this already extraordinary gem.
