Beryl vs Kunzite
Beryl and Kunzite are easy to confuse. Both sit near Mohs 7.5–8, 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 Beryl and Kunzite
- Both sit near Mohs 7.5–8, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Hold a thin edge to the light: Beryl is Transparent to translucent, Kunzite is transparent.
- They overlap in pink, but Beryl also comes in green, blue, yellow, and clear and Kunzite also comes in purple.
- Well-formed crystals give it away: Beryl is Hexagonal, Kunzite is monoclinic.

Which is more valuable?
Kunzite is usually the more valuable of the two: a typical collector specimen runs about $150 against $20 for Beryl, and premium Kunzite can reach $1500 or more.
About Beryl
Beryl is a beryllium aluminum cyclosilicate, Be3Al2Si6O18, that crystallizes in the hexagonal system as six-sided prisms. Pure beryl is colorless, but trace elements produce a family of well-known gem varieties, including green emerald, blue-green aquamarine, and pink morganite. It typically forms in granite pegmatites, where slow cooling allows large, well-formed crystals to develop.
About Kunzite
Kunzite is the pink to violet variety of spodumene. It was discovered in 1902 and named after gemologist George Frederick Kunz.
