Fire Obsidian features bright fiery flash that can sometimes contain other bright colors creating rainbow effects. It tends to run along a strand and requires considerable practice, patience, and skill to cut slabs and cabs. Fire Obsidian gets its color and flash from magnetite - tiny microscopic metal flecks embedded within the volcanic glass. It is easily one of the most rare obsidian forms known. Since fire obsidian gets its color from magnetite, it requires bright light with the stone at the right angle to display color - under normal conditions, it appears black. Recommended for experienced lapidarists familiar with working challenging materials.
WHAT MAKES IT SPECIAL
Two visible layers of high-grade fire is uncommon - most fire obsidian shows a single magnetite flow. Premium cutter status with strong probability of more fire revealed during slabbing.
PERFECT FOR
• Premium cabochon cutting
• Glass Butte collectors
• Experienced fire obsidian cutters
