I can't remember if this one was donated or if it came from the rock refill kit we got from National Geographic (we reviewed it on the rock blog) . I'm sorry. I can usually place every rock. The confusion is because I have had a very similar stone through the shop before.

So when you hunt crystals you really want points because they are worth more. When miners bring up imperfect points they quite often put them aside and these become tumblestones. This is one of those. I think.

It is amethyst with great colour.
