Obsidian is volcanic glass that forms naturally. It comes from the rapid cooling of felsic lava. Obsidian is naturally black in color and has a glassy texture and a vitreous luster. There are several shades of Obsidian including rainbow, snowflake, gold, and mahogany. Its sharp edges were a symbol that the darkness could be pierced to reveal the white light of the truth. Its polished surface resembled a mirror for looking into the future with crystal-clear clarity, and its volcanic roots speak to a well of raw energy.
