Danburite vs Clear Quartz
Danburite and Clear Quartz 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 Clear Quartz
- Both sit near Mohs 7–7.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Hold a thin edge to the light: Danburite is Transparent to translucent, Clear Quartz is transparent.
- They overlap in clear, but Danburite also comes in yellow, brown, and pink.
- Well-formed crystals give it away: Danburite is Orthorhombic, Clear Quartz is hexagonal.

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 Clear Quartz
Clear quartz, also known as rock crystal, is the purest form of quartz. It's been used for jewelry, carvings, and spiritual purposes throughout history.
