Rainbow Calsilica Cocktail Ring - ready to ship size 6.75

Rainbow Calsilica is a human-made material, showcasing layers of a rainbow of colours. I read somewhere that it's made of recycled layers of glaze from ceramics factories. After making these rings I looked into it more, and it's really hard to find information on how it's actually made (some sources are claiming that it's naturally mined, but that has been proven untrue). Anyway, it's a bit of a mystery, but I think the colours are awesome and these rings are really pretty, modern and fun!

This drop shaped gem is set on a 1.5mm thick round wire band, and is ready to ship at size 7.25 (can be resized to fit).
