About Crystals: The Stone Deck by Andrew Smart
We are loving these cards! The photos of the crystals are just gorgeous, plus on the reverse side is a description of the crystal's properties. However these descriptions are a bit different from what we normally see and are really fun. These cards are from the makers of the crystal app Stone, and are written with the same humour.
