Podlesnoite is a rare calcium-barium carbonate-fluoride mineral discovered in the unique geological environment of the Khibiny Massif. Collectors look for its characteristic tabular crystal habit often associated with other alkaline pegmatite minerals. It is a prized rarity due to its extremely limited occurrence in alkaline rock complexes.

Is this podlesnoite?

5-step field check

Run through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.

1
Test the hardness
Try to scratch podlesnoite with a known reference. Podlesnoite sits at Mohs 4, softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Podlesnoite leaves a white streak.
3
Read the luster
Hold the specimen under a strong light. Podlesnoite typically shows a vitreous luster.
4
Match the color range
Compare against the expected color range: colorless, white.
5
Look at form & habit
Crystal system: orthorhombic. Typical habit: tabular crystals.

Where rockhounds find podlesnoite

Classic worldwide localities

Khibiny Massif, Kola Peninsula, Russia

Field-hunting tip

Look in alkaline pegmatites country, the host setting where podlesnoite typically forms. If you start seeing quartz, aegirine, microcline 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.

Common questions

How do you identify podlesnoite?+

Mohs hardness is 4. It typically shows a vitreous luster. The streak is white. Common colors include colorless, white.

Where is podlesnoite found?+

Notable localities include Khibiny Massif, Kola Peninsula, Russia.

How much is podlesnoite worth?+
