Waterstar

Also known as achroite or colorless tourmaline, waterstar is a rare, colorless, sparkling stone. Only stones of this material that are entirely free of flaws and inclusions are valued for gemstone use (as a fancy stone). Crystals of this flawless type yield quite large faceted gemstones. Gemstone-quality waterstar works as a weak augmenting material component for spells that create force effects.
