Burovaite-Ca is a rare member of the labuntsovite group found primarily in alkaline pegmatites. It typically occurs as small, white prismatic crystals or radial clusters, often associated with other rare alkaline minerals in the Kola Peninsula.
Is this burovaite-ca?
4-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.
- 2Read the lusterHold the specimen under a strong light. Luster: vitreous.
- 3Match the color rangeCompare against the expected color range: white.
- 4Look at form & habitCrystal system: monoclinic. Typical habit: prismatic crystals, radial aggregates.

Field-hunting tip
Where it forms: In cavities in microcline in the hydrothermal zone of aegirine-microcline pegmatite. If you start seeing labuntsovite-mn, lemmleynite-ba, analcime in float, you are in the right ground. Typical habit: prismatic crystals, radial aggregates. Train your eye for that shape before scanning the outcrop.
