Alexandrite Cat’s Eye Stone

Alexandrite Cat’s Eye, a rare and premium variety of chrysoberyl, is renowned for its unique optical phenomena: color change and chatoyancy. This gemstone, composed of beryllium aluminum oxide (BeAl₂O₄), exhibits a striking color shift, typically from greenish-blue in daylight to reddish-purple under incandescent light, due to trace amounts of chromium substituting for aluminum in its crystal lattice. The chatoyancy, or "cat’s eye" effect, results from parallel fibrous inclusions or cavities within the stone, which reflect light into a sharp, silvery band resembling a feline pupil.

This optical effect is most pronounced in cabochon-cut stones, where the dome shape enhances the light reflection.With a Mohs hardness of 8.5, alexandrite cat’s eye is durable, making it suitable for jewelry. Its orthorhombic crystal structure contributes to its toughness and resistance to scratches. Major sources of Alexandrite ketu stone include Sri Lanka, Brazil, and Russia, with Sri Lankan stones often showing the finest color change. The gem’s rarity and dual optical properties make it highly valuable, often commanding premium prices. Care involves avoiding harsh chemicals and ultrasonic cleaners to preserve its inclusions. Alexandrite cat’s eye is prized by collectors and gem enthusiasts for its mesmerizing beauty and rarity.

Alexandrite Cats Eye Stone Price

The price of Alexandrite Cat’s Eye gemstone, one of the rarest gemstones in the world, varies significantly based on the quality of its dual optical effects: color change and chatoyancy. High-grade stones with a sharp, well-centered eye and a distinct color shift from green in daylight to red under incandescent light are the most valuable, often commanding prices between $500 and $5,000 per carat or more for fine, clean, and well-cut cabochons. Factors such as transparency, color intensity, carat weight, and origin (e.g., Sri Lanka, India, or Brazil) greatly influence value.

Larger stones over 1 carat with excellent clarity and strong optical effects are exceptionally rare and can reach premium prices. Synthetic or treated Alexandrite Cat’s Eye is available at lower costs, but natural, untreated specimens are highly sought after by collectors and jewelers. Due to its rarity and beauty, Alexandrite Cat’s Eye remains a top-tier investment gem, and certification from a reputable gemological lab is recommended to verify authenticity and ensure fair pricing.
