caitirin and I went to the Mustard Seed yesterday, which is a natural/metaphysical shop nearby. It's such a calm, welcoming place :) But they were having a sale on crystals, so got a couple of a kind I had always wanted but thought were a little too expensive. They were definitely within my range yesterday, though, and they're so pretty! The lady at the store said they were called shaman's stones. They're both quartz with other minerals in them.
I got a dark one, which looks like it has a forest inside it:

And a gorgeous clear one:

Another shot of the clear one:

Click the pictures to go to Flickr and then on "all sizes" to embiggen! I love them :3
