How durable is chrysoberyl?

Chrysoberyl is one of the more durable gemstones you can get, with a pretty formidable Mohs hardness of 8.5 and an exceptional toughness that fights off chipping and scratching with ease.

It also has high density and a complete lack of structural cleavage, so the mineral stays astonishingly stable. Whether you see it faceted as a clear stone or in its chatoyant “cat’s-eye” variant, it behaves like a steadfast jewel. It can take constant daily wear without turning dull, so it is frequently chosen for men’s rings and for settings exposed to heavy friction.
