Borovskite is an extremely rare palladium-antimony-telluride mineral typically found as microscopic inclusions in platinum-group ore deposits. It is almost exclusively found by professional prospectors or lab analysis within specialized ultramafic rock environments. Collectors value it as an exotic member of the platinum group of minerals.
Is this borovskite?
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 borovskite with a known reference. Borovskite sits at Mohs 3, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Streak: black.
- 3Read the lusterHold the specimen under a strong light. Luster: metallic.
- 4Match the color rangeCompare against the expected color range: dark gray.
- 5Look at form & habitCrystal system: cubic. Typical habit: anhedral grains.

Field-hunting tip
Where it forms: In massive pentlandite-chalcopyrite-pyrrhotite ores of hydrothermal origin. If you start seeing pyrrhotite, chalcopyrite, altaite in float, you are in the right ground. Typical habit: anhedral grains. Train your eye for that shape before scanning the outcrop.
