Orlovite is a very rare potassium-lithium-titanium mica mineral primarily found in the Murun Massif in Siberia. It typically occurs as small, pale, platy crystals within alkaline igneous rock environments and is primarily sought after by advanced mineral collectors.
Is this orlovite?
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 orlovite with a known reference. Orlovite sits at Mohs 2.5-3 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Orlovite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Orlovite typically shows a pearly luster.
- 4Match the color rangeCompare against the expected color range: colorless, pale yellow, white.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: platy crystals.

Field-hunting tip
Look in alkaline pegmatites country — that is the host setting where orlovite typically forms. If you start seeing potassium feldspar, aegirine, tinaksite in float, you are in the right ground. Field specimens usually show a platy crystals habit, so train your eye for that shape before scanning the outcrop.
