In-game description
"Bloodstone is a dark greenish gray variety of quartz flecked with red crystal impurities. Ninety percent of the bloodstones in the Realms come from the Galena Mountains in Damara, and most of those from a single mine in Bloodstone Pass. The border pass is heavily fortified and guarded as bloodstones are the chief export for this region."
