Olympite is an extremely rare phosphate mineral discovered at the fumaroles of the Tolbachik volcano in Russia. It typically occurs as small, colorless to white tabular crystals within volcanic sublimate deposits and is highly sought after by advanced mineral collectors.
Is this olympite?
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 olympite with a known reference. Olympite sits at Mohs 4 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Olympite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Olympite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: white, colorless.
- 5Look at form & habitCrystal system: trigonal. Typical habit: tabular crystals.

Field-hunting tip
Look in fumarole deposits country — that is the host setting where olympite typically forms. If you start seeing tolbachikite, tenorite, sylvite in float, you are in the right ground. Field specimens usually show a tabular crystals habit, so train your eye for that shape before scanning the outcrop.
