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 2.5 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Babkinite leaves a black streak.
- 3Read the lusterHold the specimen under a strong light. Babkinite typically shows a metallic luster.
- 4Match the color rangeCompare against the expected color range: lead-gray, tin-white.
- 5Look at form & habitCrystal system: orthorhombic. Typical habit: anhedral grains, interstitial masses.

Field-hunting tip
Look in epithermal gold deposits country — that is the host setting where babkinite typically forms. If you start seeing galena, gold, chalcopyrite in float, you are in the right ground. Field specimens usually show a anhedral grains, interstitial masses habit, so train your eye for that shape before scanning the outcrop.
