Is this alsakharovite-zn?

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 alsakharovite-zn with a known reference. Alsakharovite-Zn sits at Mohs 5 — softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Alsakharovite-Zn leaves a white streak.
3
Read the luster
Hold the specimen under a strong light. Alsakharovite-Zn 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: monoclinic. Typical habit: prismatic crystals.

Field-hunting tip

Look in alkaline pegmatites country — that is the host setting where alsakharovite-zn 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.
