How to Tell If a Chrysoberyl Is Real – Gemstone Identification Guide
Chrysoberyl is a gemstone cherished for its remarkable properties, including the striking cat's eye effect and the rare colour-changing alexandrite variety. Ensuring the authenticity of chrysoberyl is crucial for collectors, jewellers, and buyers alike. This guide offers comprehensive insights into identifying genuine chrysoberyl, helping you make informed purchasing decisions.
In short: Genuine chrysoberyl (Mohs 8.5, third-hardest natural gemstone after diamond and corundum) shows refractive index 1.745-1.755 and specific gravity 3.5-3.84. Three varieties: yellow-green chrysoberyl (most common), cat's-eye chrysoberyl (sharp chatoyant band) and alexandrite (colour-changing). Always confirm with a gemmologist's report — particularly for cat's-eye and alexandrite.
