Pavlovskyite is a rare calcium silicate fluoride mineral discovered in the contact-metamorphic rocks of the Sakha Republic in Russia. It typically occurs as small, colorless to pale yellow tabular crystals within skarn environments, often associated with other calcium-rich silicates.
Is this pavlovskyite?
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 pavlovskyite with a known reference. Pavlovskyite sits at Mohs 6 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Pavlovskyite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Pavlovskyite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: colorless, white, pale yellow.
- 5Look at form & habitCrystal system: orthorhombic. Typical habit: tabular crystals.

Field-hunting tip
Look in skarn country — that is the host setting where pavlovskyite typically forms. If you start seeing wollastonite, gehlenite, fluorapatite 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.
