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 kuannersuite-(ce) with a known reference. Kuannersuite-(Ce) sits at Mohs 3.5-4 — softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Kuannersuite-(Ce) leaves a white streak.
3
Read the luster
Hold the specimen under a strong light. Kuannersuite-(Ce) typically shows a vitreous luster.
4
Match the color range
Compare against the expected color range: yellow, brown, red-brown.
5
Look at form & habit
Crystal system: orthorhombic. Typical habit: prismatic crystals.

Where rockhounds find kuannersuite-(ce)

Classic worldwide localities

Ilimaussaq complex, Greenland

Field-hunting tip

Look in alkaline pegmatites country — that is the host setting where kuannersuite-(ce) typically forms. If you start seeing aegirine, microcline, sodalite 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.
