✨ What makes Topaz special?
- It combines hardness with a hidden weakness: Topaz reaches 8 on the Mohs scale, yet its perfect basal cleavage allows a sharp blow to divide the crystal along one structural plane.
- Its crystals often reveal clear geometry: long or short orthorhombic prisms commonly display vertical striations and complex, sharply angled terminations.
- Its colour story is remarkably broad: natural gems range from colourless and pale blue to golden orange, pink and rare red, while treatment expands the commercial palette.
