Zakharovite is a rare sodium-manganese silicate primarily found in the alkaline igneous rocks of the Kola Peninsula. It typically forms attractive yellow to brownish platy or radial aggregates within pegmatite cavities, often associated with other rare alkaline minerals.
Is this zakharovite?
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 zakharovite with a known reference. Zakharovite sits at Mohs 2-3 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Zakharovite leaves a yellow streak.
- 3Read the lusterHold the specimen under a strong light. Zakharovite typically shows a pearly luster.
- 4Match the color rangeCompare against the expected color range: yellow, brown.
- 5Look at form & habitCrystal system: trigonal. Typical habit: platy crystals, radial aggregates.
Often confused with
Zakharovite vs. its common look-alikes — and how to tell them apart in the field.
How to tell apart: Steacyite is the harder of the two (Mohs 5 vs. 2-3); streak differs — Zakharovite leaves yellow, Steacyite leaves white; luster reads pearly on Zakharovite and vitreous on Steacyite.
How to tell apart: Gonnardite is the harder of the two (Mohs 5 vs. 2-3); streak differs — Zakharovite leaves yellow, Gonnardite leaves white; luster reads pearly on Zakharovite and vitreous on Gonnardite.

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