This listing is for a rough slab of Ribbon Obsidian mixed with Triple Flow Obsidian, aka Mahogany Obsidian, from Glass Butte Oregon, 100% natural.  It can be used for lapidary to make cabochons or as a display specimen.  Would also be good for flint knapping.

Triple Flow Obsidian is a gorgeous form of mahogany obsidian that often has multiple grains and currents of flow. Tri-Flow normally includes clear, black and brown/red obsidian mixed. These mixes of colors may be parallel flows, or random mixes looking like stirred mixture or it may be splotchy. The color generally comes from Magnetite that was present in the lava flow.

In addition to its decorative use, obsidian has been used to make smooth and sharp surgical blades and arrowheads due to its lack of cleavage and acute edges when broken. Stone Age people used obsidian for weapons and implements, Native Americans formed it into arrowheads and the Incans used it for weapons, mirrors and masks.

If you’ll be displaying the slab in your collection, we have easel stands which can be purchased separately.  We have 2″ and 3″ ones available.
