Goryainovite is a rare calcium fluoride mineral that is essentially an octahedral form of fluorite. It is primarily identified within the alkaline complexes of the Kovdor massif and is prized by advanced mineral collectors for its specific geological occurrence.

Is this goryainovite?

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 goryainovite with a known reference. Goryainovite 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. Goryainovite leaves a white streak.
3
Read the luster
Hold the specimen under a strong light. Goryainovite 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: cubic. Typical habit: equant crystals.

Where rockhounds find goryainovite

Classic worldwide localities

Kovdor Massif, Russia

Field-hunting tip

Look in alkaline igneous rocks country — that is the host setting where goryainovite typically forms. If you start seeing baddeleyite, magnetite, forsterite in float, you are in the right ground. Field specimens usually show a equant crystals habit, so train your eye for that shape before scanning the outcrop.
