The material, examined
What the name tells you
Hardness describes resistance to scratching, not toughness. Topaz’s cleavage is a practical reminder that a high number does not make a crystal safe from every knock.
A useful question at the counter
Is it actually topaz, and what treatments are disclosed? Color descriptions cannot answer either question alone.
A note for your collection
Avoid impacts and sudden temperature changes. High scratch hardness does not prevent splitting along cleavage.
