Florenskyite is a extremely rare iron titanium phosphide mineral discovered in the Kaidun meteorite. It occurs as microscopic inclusions within metallic phases and is highly prized by meteorite collectors and researchers for its unique extraterrestrial origin.
Is this florenskyite?
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 florenskyite with a known reference. Florenskyite 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. Florenskyite leaves a gray streak.
- 3Read the lusterHold the specimen under a strong light. Florenskyite typically shows a metallic luster.
- 4Match the color rangeCompare against the expected color range: white, gray.
- 5Look at form & habitCrystal system: trigonal. Typical habit: anhedral grains.

Field-hunting tip
Look in meteorites country — that is the host setting where florenskyite typically forms. If you start seeing kamacite, taenite, schreibersite in float, you are in the right ground. Field specimens usually show a anhedral grains habit, so train your eye for that shape before scanning the outcrop.
