Villiaumite, polished. Russia

Villiaumite is mineralized sodium fluoride.

So, yes, it is toxic.

But it can be handled safely, just wash your hands after. And there is NO LICKING this pretty candy rock!

Collected from Koashva Mtn., Khibiny Massif, Murmansk Oblast, Kola Peninsula, Russia.

It is water-soluble so the miners use glycerin to polish.

Will come in the holder seen in the photos.

This piece measures roughly 1” x 1.5” and weighs just over 24 grams.
