Babkinite is an extremely rare lead-bismuth sulfoselenide-telluride mineral known primarily from epithermal gold-telluride deposits. It is usually found as microscopic inclusions or intergrowths with other lead minerals and tellurides, making it difficult for collectors to acquire as a macro specimen.
Is this babkinite?
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 babkinite with a known reference. Babkinite sits at Mohs ~2, 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: silvery gray.
- 5Look at form & habitCrystal system: trigonal. Typical habit: aggregates, platy.

Field-hunting tip
Where it forms: In a hydrothermal deposit in sediments, near their contact with a granite intrusion. If you start seeing arsenopyrite, stannite, tetrahedrite in float, you are in the right ground. Typical habit: aggregates, platy. Train your eye for that shape before scanning the outcrop.
