Seller:rainshadow_gems✉️(566)100%, Location:Port Townsend, Washington, Ships to: Worldwide, Item:173619448380Fire Obsidian - 1 Kilogram Lots - 'B' Grades & Better - Glass Buttes, OR. Multiple Lots For Sale,... Buy-It-Now!! Listed here is a 1-kilogram (1000 gram) lot of rough & natural obsidian from Little Glass Butte in Central Oregon. Each of these pieces has a broad flash of color (i.e. a combination of red, amber, orange, green & occasionally a bit of purple or blue) somewhere in the flow banding: Fire Obsidian !! These pieces were culled from a larger lot as 'seconds' for one reason or another. Some of these chunks may yield very gemmy, however small, cabochons. Others in this lot have a fair amount of fire in the flow banding but the color is somewhat dull or the stone around the fire may be a bit hazy, or the flow bands too convoluted to cob easily. For the most part, this material falls under the category of midnight lace and gold-sheen obsidian. Altogether, there is a lot more obsidian than there is fire. All of these pieces are 100% natural in their rough state and every one has at least one fire layer. The photos presented here are only a representation of the actual lot for sale. The pieces readily showing fire were photographed wet or immersed in water to increase the refractive angle of the light and show the color better in the picture. The fire is near impossible to photograph in the rough, usually. The lot will consist of about 10 to 18 pieces. Pieces range in size up to about 130 grams. These pieces are 100% usable for cabbing, carving, slabbing, knapping, tumbling, etc. Please note: if cutting exclusively to expose the fire obsidian there will be a large amount of waste from rough-to-preform as the 'fire' runs in very finite flow bands. Most of these pieces do not exhibit a lot of color, but then, the flow bands are mostly concealed within the stones. Some of these pieces may yield hidden surprises. I do my best to assure that the pieces offered are worthy of cutting, but please keep in mind, when bidding, that this is a parcel of B-grade material. Free shipping is offered for this parcel, in the United States only, via U.S.P.S. Priority Mail with Tracking. International postage will also be by U.S.P.S. Priority Mail (International), with no handling fee charged. I am happy to discount and combine postage for multiple purchases by international buyers. In this case, please inquire about combined shipping and I will send you an invoice.Thanks for looking & please have a look at my other items for sale. **** This is Fire Obsidian…Dream in color again! Presented here is a sample of true fire obsidian from Little Glass Butte in the high desert of Central Oregon. This is the only known locale where this type of material can be found. Once seen in person, fire obsidian cannot be confused with any other type of stone or obsidian, although the name is sometimes misapplied to other sheen obsidians with flame like patterns of orange or red against smoky coloration. Fire obsidian is unique for the thin bands of color that it contains, which are often intricately patterned and are occasionally extremely vivid and highly reflective. Fire obsidian is unlike any other phenomenal gem. While its color-play is reminiscent of fossil ammolite or of precious opal, the chemistry behind the color phenomena is inherently different. The color in fire obsidian is produced by light reflecting off of a polarized lattice of sub-micron scale magnetite crystals. This network of micro-crystals is arranged in such a way as to create quantum wave interference of the light, hence emitting colors of different frequencies. While this physical mechanism that causes the color play in fire obsidian is nothing unusual in the realm of color and light, the particular manifestation of color, pattern and brilliance can be found in no other member of the mineral kingdom. As with any rock or mineral species, not all specimens will embody the same qualities of color, clarity, pattern or aesthetics. Like many gems and minerals, obsidian can be highly transparent to completely opaque. It can be crystal clear, or heavily included with impurities and accessory minerals. Fire obsidian is no exception to the rule.Condition:New, Restocking Fee:No, All returns accepted:Returns Accepted, Item must be returned within:14 Days, Refund will be given as:Money Back, Return shipping will be paid by:Buyer

• Fire obsidian is unique for the thin bands of color that it contains, which are often intricately patterned and are occasionally extremely vivid and highly reflective. Fire obsidian is unlike any other phenomenal gem.
• Obsidian is also used in making opal doublets and opal triplets. Thin slices or chips of opal are glued to a thin slice of obsidian to make a composite stone. The black obsidian provides an inexpensive and color-contrasting background that makes opal's colorful fire much more obvious.
