Spodumene (Kunzite) identification and geology

Pink to violet gem variety of spodumene colored by manganese. Discovered in 1902 and named after gemologist G.F. Kunz. Color: Pink, violet, lilac. Luster: Vitreous. Streak: White. Cleavage: Perfect in two directions. Hardness: 6.5-7. Transparency: Transparent. Crystal system: Monoclinic. Chemical formula: LiAlSi₂O₆. Specific gravity: 3.15-3.21. Formation: Forms in lithium-rich granitic pegmatites; color from Mn³⁺ substitution. Can fade with prolonged light exposure. Common geological settings: Afghanistan, Brazil, Madagascar, USA California ; found in granitic pegmatites. Common look-alikes and related entries: Morganite, Amethyst, Rose Quartz.

Common questions

What is Spodumene Kunzite?
Pink to violet gem variety of spodumene colored by manganese. Discovered in 1902 and named after gemologist G.F. Kunz.
How can you identify Spodumene Kunzite?
Compare several properties rather than relying on colour alone. This entry records colour: Pink, violet, lilac; lustre: Vitreous; streak: White; Mohs hardness: 6.5-7; cleavage: Perfect in two directions; crystal system: Monoclinic; transparency: Transparent. Confirm an important identification with additional field tests or qualified laboratory work.
How does Spodumene Kunzite form?
Forms in lithium-rich granitic pegmatites; color from Mn³⁺ substitution. Can fade with prolonged light exposure.
Where is Spodumene Kunzite commonly found?
Afghanistan, Brazil, Madagascar, USA California ; found in granitic pegmatites.
What is Spodumene Kunzite commonly confused with?
Spodumene Kunzite may be confused with Morganite, Amethyst, Rose Quartz. Compare multiple diagnostic properties because colour and surface appearance can overlap.
