I also love crystals, in fact in my country I had several amethysts in my house, but they were so big that with the migration I could not bring them.
I have to look for a store like the one you visited here to buy some accessories with stones that I can take with me.
It's always a pleasure to meet a crystal lover. It's the same problem with me, back home I have some real beautiful big ones and I cannot get them here so I settle down with these small ones. Else I would love to have rocks around in my home ...hehe
