Strakhovite is an exceptionally rare silicate mineral discovered in alkaline pegmatites of the Kola Peninsula. It typically occurs as small, pale yellow tabular crystals and is highly prized by advanced mineral collectors due to its very limited global occurrence.
Is this strakhovite?
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 strakhovite with a known reference. Strakhovite 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. Streak: green.
- 3Read the lusterHold the specimen under a strong light. Luster: vitreous to greasy.
- 4Match the color rangeCompare against the expected color range: black, greenish black, dark olive green.
- 5Look at form & habitCrystal system: orthorhombic. Typical habit: granular.

Field-hunting tip
Where it forms: At the contact between braunite ore and alkali basalt. If you start seeing pectolite, aegirine, microcline in float, you are in the right ground. Typical habit: granular. Train your eye for that shape before scanning the outcrop.
