Cats eyes tourmaline Crystals- 72 g - (1)

Tourmaline is a complex boron silicate mineral noted for its remarkable range of colors and unique crystal forms. The 'cat's eye' effect described in certain tourmaline crystals arises from chatoyancy—a reflective optical phenomenon where a band of reflected light appears to move across the gemstone surface. This effect occurs because of fibrous inclusions or internal structural features aligned parallel within the crystal. A cat's eye tourmaline presents a captivating street-light-like glow that enhances the gemstone's depth and catchiness in light. Tourmalines are highly valued in both mineral collections and jewelry and can exhibit colors from greens and browns to rarer shades like pink and blue. Their complex atomic structure lends to various physical properties and makes them a favorite among gemologists and collectors alike. The distinct optical qualities combined with a durable nature contribute to tourmaline's popularity.
