Rhyolite ~

Rhyolite is a type of igneous rock, which means it formed through the cooling and solidification of volcanic lava.  

Knowing this makes this mineral rather special for me: the thought that the stone from which these beads were made was once flung from a volcano in a molten state really tickles my imagination, and it seems strange to be wearing such a thing around one's neck!  

I'd be pleased to know which volcano it was and how long ago, but didn't think to ask at the time.  Often retailers don't know this sort of thing, but often they do and can tell you quite a bit, which can add considerably to our appreciation of them.
