Obsidian

Also called natural glass or volcanic glass, obsidian is a hard, glossy, and black ornamental stone that is volcanic in origin. It is often chipped into arrowheads or, in larger chunks, used to make bladed weapons. The ornamental grade of stone is usually polished and smoothed.

An inferior form of obsidian called pitchstone is both duller and rougher than volcanic glass and is used for many grinding purposes. Many folk wear polished and tumbled obsidian for adornment, either as jewelry or as inlays on copper or bronze bracers and pectorals. Obsidian is one of the most favored materials for the carving of small figurines and ornamental finger-bowls. Obsidian can be used as an augmenting material in spells that form weapons, such as blade barrier. It is often sought for sacrificial daggers, especially when dealing with devils and demons. Whether this material has any effect on mystical sacrifice is unknown, the evil nature and variability of the events meaning what little research done on them is spotty at best.

The jungle of eastern Coricona is the most common source of obsidian, and one of the few sources for incredibly high quality and ornamental obsidian. How this is true is unknown, as there is no evidence of past or present volcanic activity in the jungle other than the presence of obsidian.
