Lovely stones! :)
You can get some interesting carved pieces of Malachite ~ there's a nice shop in Glastonbury which had lots!
Does that Obsidian sphere have a silver sheen? I'll have to did out my tumble which has been packed away for too long.
I've been thinking about saving up for a cabinet to store all of my stones. There's some nice bespoke ones made out of oak, with lots of drawers. Another idea is to get a few artist boxes with removable trays. Hmm...
