Mohite is a rare copper tin sulfide, typically gray with a greenish tint. It occurs in hydrothermal origin. Associated minerals include tetrahedrite, famatinite and kuramite. It was first described from Kochbulak gold deposit, Chatkal-Kuramin Mountains, eastern Uzbekistan.
Is this mohite?
5-step field checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry to scratch mohite with a known reference. Mohite sits at Mohs 4, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Streak: gray.
- 3Read the lusterHold the specimen under a strong light. Luster: metallic.
- 4Match the color rangeCompare against the expected color range: greenish gray.
- 5Look at form & habitCrystal system: triclinic. Typical habit: microscopic crystals.
Often confused with
Mohite vs. its common look-alikes, and how to tell them apart in the field.

How to tell apart: Mohite is noticeably harder (Mohs 4 vs. 2.7); streak differs, so Mohite leaves gray, Berzelianite leaves shining.

How to tell apart: Mohite is noticeably harder (Mohs 4 vs. 3); streak differs, so Mohite leaves gray, Umangite leaves black.

How to tell apart: Mohite is noticeably harder (Mohs 4 vs. 2.5-3); streak differs, so Mohite leaves gray, Chalcocite leaves blackish lead-gray.
