Sphene

Sphene is a soft, brittle precious stone easily worked by unskilled cutters (like scapra). It comes in various yellow to green shades, but a fine emerald green is the most prized hue. Sphene crystals can be cut into beautiful, sparkling, faceted gemstones of small and medium size. Sphene can be used as an augmenting component in spells that deal with thoughts and memories.
