Paratsepinite-Ba is a rare member of the complex labuntsovite group of minerals, typically found in alkaline igneous environments. It occurs as small, glassy prismatic crystals that are challenging to distinguish from other group members without analytical testing.
Is this paratsepinite-ba?
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 paratsepinite-ba with a known reference. Paratsepinite-Ba 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. Paratsepinite-Ba leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Paratsepinite-Ba typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: yellow, brown, colorless.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: prismatic crystals.

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