Rocks Off

My wife is a slightly fanatical collector of shiny things. She makes jewellery, and hoards collects jewellery, sometimes she just sits and sorts through her gems and jewels like Scrooge McDuck in his vault. She's in the middle of polishing some semi precious stones and they're starting to look more like the finished product than the rough rocks they were before. They're not shiny enough yet though, more tumbling to go.
