Danburite vs Topaz
Danburite and Topaz are easy to confuse. Both sit near Mohs 7–7.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Danburite and Topaz
- Both sit near Mohs 7–7.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Topaz feels noticeably heavier for its size (specific gravity 3.5 versus 2.97–3.02 for Danburite).
- Hold a thin edge to the light: Danburite is Transparent to translucent, Topaz is transparent.
- They overlap in clear, yellow, and pink, but Danburite also comes in brown and Topaz also comes in blue and orange.
- Well-formed crystals give it away: Danburite is Orthorhombic, Topaz is orthorhombic.

About Danburite
Danburite is calcium borosilicate, CaB2Si2O8, crystallizing in the orthorhombic system as prismatic crystals that closely resemble topaz at a glance. It was first identified near Danbury, Connecticut, which gave the mineral its name, though the finest modern specimens come from Mexico and Madagascar. Its glassy luster and typically pale coloring make it a favorite among faceted-gem collectors seeking an affordable topaz alternative.
About Topaz
Topaz is an aluminum silicate mineral prized for its hardness and brilliant colors. Imperial topaz (orange-pink) from Brazil is most valuable.
