Burovaite-Ca is a rare member of the labuntsovite group found primarily in alkaline pegmatites. It typically occurs as small, pale yellow prismatic crystals or radial clusters, often associated with other rare alkaline minerals in the Kola Peninsula.
Is this burovaite-ca?
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 burovaite-ca with a known reference. Burovaite-Ca sits at Mohs 5 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Burovaite-Ca leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Burovaite-Ca typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: yellow, brownish-yellow, pale yellow.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: prismatic crystals, radial aggregates.

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