Andrianovite is a rare member of the eudialyte group found in alkaline igneous complexes. It typically presents as small yellow to brown granular aggregates and is primarily of interest to systematic mineral collectors specializing in complex silicates.

Is this andrianovite?

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 andrianovite with a known reference. Andrianovite sits at Mohs 5-6 — softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Andrianovite leaves a white streak.
3
Read the luster
Hold the specimen under a strong light. Andrianovite typically shows a vitreous luster.
4
Match the color range
Compare against the expected color range: yellow, brown.
5
Look at form & habit
Crystal system: trigonal. Typical habit: granular.

Where rockhounds find andrianovite

Classic worldwide localities

Kola Peninsula, Russia

Field-hunting tip

Look in alkaline igneous rocks country — that is the host setting where andrianovite typically forms. If you start seeing nepheline, aegirine, microcline in float, you are in the right ground. Field specimens usually show a granular habit, so train your eye for that shape before scanning the outcrop.
