{"title":"Natural Cat's Eye Chrysoberyl - Chatoyancy Phenomenon Stones","description":"\u003cp\u003eNatural cat's eye chrysoberyl is a phenomenon gemstone displaying chatoyancy - a sharp single band of light that moves smoothly across the surface of a cabochon-cut stone as it rotates under light. The effect mimics the vertical slit pupil of a cat's eye in headlights. Fine cat's eye chrysoberyl is one of the rarest phenomenon gemstones in the world and has been prized for centuries, particularly in South Asia where it carries deep cultural significance. For the broader chrysoberyl family including faceted stones, see our \u003ca href=\"\/en-cn\/collections\/natural-chrysoberyl-loose-stones-sri-lanka\"\u003echrysoberyl collection\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Our Natural Cat's Eye Chrysoberyl\u003c\/h2\u003e\n\n\u003cp\u003eOur cat's eye chrysoberyls are sourced primarily from Sri Lanka, one of the world's leading sources. Every stone is \u003cstrong\u003enatural and untreated\u003c\/strong\u003e - chrysoberyl rarely requires any enhancement. We hand-select for eye sharpness, body colour, and the milk-and-honey effect that distinguishes a great cat's eye from an ordinary one. Premium pieces ship with \u003cstrong\u003eGIA reports\u003c\/strong\u003e.

A fuzzy or off-centre eye significantly reduces value. \u003cstrong\u003eMilk and honey effect.\u003c\/strong\u003e Under directional light, one half of the dome appears creamy white (the milk) while the other glows golden (the honey). The stronger and more distinct this contrast, the finer the stone. \u003cstrong\u003eBody colour.\u003c\/strong\u003e The finest Ceylon cat's eyes show a vivid golden-green to honey-yellow body. Pale or brownish body colours are less prized. \u003cstrong\u003eTransparency.\u003c\/strong\u003e Translucent to semi-translucent cabochons with depth are more desirable than opaque ones.\u003c\/p\u003e\n\n\u003ch2\u003eCollector and Jyotish Significance\u003c\/h2\u003e\n\n\u003cp\u003eCat's eye chrysoberyl (Lahsuniya) is the prescribed gemstone for Ketu in Jyotish (Vedic astrology).
