I've always loved grandidierite- the really good material, I think the colour is beautiful. Gemporia have had the whole range from opaque dark cabochons to loriques since the new Madagascar deposit was found.
I bought a couple today as I got the rose quartz one and found it light and comfy, and cute. Don't mind for a fiver - it's not pretending to be more than it is (if you ignore Lynn's metaphysical stuff)
