Mukhinite is a rare vanadium-dominant member of the epidote group, characterized by its deep green color resulting from vanadium substitution. It is primarily found in metamorphic environments, often forming elongated prismatic crystals. Collectors typically find it in specialized Russian mineral localities associated with skarn-type mineralization.
Is this mukhinite?
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 mukhinite with a known reference. Mukhinite sits at Mohs 6-7 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Mukhinite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Mukhinite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: dark green, brownish green.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: prismatic crystals.

Field-hunting tip
Look in metamorphic rocks country — that is the host setting where mukhinite typically forms. If you start seeing vesuvianite, diopside, calcite in float, you are in the right ground. Field specimens usually show a prismatic crystals habit, so train your eye for that shape before scanning the outcrop.
