cat’s Eye
Cat’s-eye chrysoberyl is mostly sourced from Sri Lanka but many of those are irregular and unsymmetrical for jewellery making in such a way that having gemstone quality deposits of cat’s eye are even rarer.
Having the chatoyant effect that sweeps like a straight line across the stone’s surface, the presence of microscopic needle-like inclusions of rutile or hollow tubes produces a chatoyant effect visible as a single ray of light across the surface. The gemstone must be juxtaposed to display its best advantage in a form of cabochon. Although there is other gemstones display chatoyancy, cat’s-eye chrysoberyl is the only chatoyant mineral earns its name. The chatoyant band is distinct, straight and silver-white colour, extending from girdle to girdle and the body colour of a gem-quality cat’s-eye possess a semi-translucent golden yellow to slightly greenish yellow colour.
