Kunzite vs Morganite
Kunzite and Morganite are easy to confuse. Both sit near Mohs 7, 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 Kunzite and Morganite
- Both sit near Mohs 7, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Well-formed crystals give it away: Kunzite is monoclinic, Morganite is hexagonal.
