Obsidian is from obsianus lapis meaning stone of Obsuis, its supposed discoverer. Obsidian is a lustrous volcanic glass formed in the flaming core of the earth and transported to the surface in volcanic eruptions. Also called lava glass, obsidian is fairly fragile. Although the color range and related names are varied, it is generally deep black, black with flecks of a white mineral called phenocryst (snowflake obsidian), dark green or brown.
Obsidian was a valued trading material among the North American Native tribes who used it to make arrowheads and to deepen their insight during rituals and celebrations.
