Raindrop

Raindrop is the name given to cassiterite, specifically to the flawless, colorless crystals or areas in larger, dark brown crystals. These can yield small, hard, durable faceted gems. The stones are usually fashioned into velvet-polished teardrop shapes for use on cloak and other garments, hence their name. The colored material is much less valuable and known as woodtine. A typical specimen has a base value of 500gp.
