I am an Independent Studio Jeweler and have an Associates of Fine Arts. I specialize in hand-crafted, historically inspired, one-of-a-kind jewelry using a variety of techniques, including, but not limited to: chainmaille, wire-work, metalsmithing, and Steampunk. Each ring has been coiled, cut, and woven by hand with many clasps also being handmade.
Fire Obsidian is very like the Rainbow Obsidian I blogged about last time. Just like Rainbow Obsidian, Fire Obsidian's interesting iridescence (or 'fire' as it is also called) is caused by the presence of Magnetite microcrystals. In Fire Obsidian, these microcrystals are in thin layers, which are roughly the thickness of the wavelength of light, whereas, in Rainbow Obsidian the layers of Magnetite microcrystals are in thicker volume and so gives the Obsidian larger bands of colour. Fire Obsidian is only known to be found in Lake County, Oregon.
