Properties of topaz

Topaz forms in igneous rocks and pegmatites at high temperatures and is found in Brazil, Pakistan, Russia, Sri Lanka, Nigeria, and Mexico, among other places.

With a hardness of 8 on the Mohs scale, topaz is highly resistant to scratches and is therefore suitable for jewelry that is worn regularly.

However, topaz has a distinct cleavage plane. As a result, the stone can become damaged or split if subjected to a hard blow or an accidental impact. A secure setting and careful handling are therefore essential, especially for rings.
