Kanoite is a relatively rare manganese-rich pyroxene that typically occurs in highly metamorphosed manganese deposits. It is often found as small, granular masses and can be challenging to distinguish from other pyroxene group minerals without chemical analysis. Collectors primarily look for it in classic manganese mining localities associated with other manganese silicates and carbonates.
Is this kanoite?
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 kanoite with a known reference. Kanoite sits at Mohs 5-6 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Kanoite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Kanoite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: pink, pale brown, colorless.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: granular, massive.

Field-hunting tip
Look in manganese-rich metamorphic rocks country — that is the host setting where kanoite typically forms. If you start seeing tephroite, rhodochrosite, hausmannite in float, you are in the right ground. Field specimens usually show a granular, massive habit, so train your eye for that shape before scanning the outcrop.
