Product Description

Black Obsidian

Igneous Rock Specimen

Oregon, USA

Specifications: Each specimen is more than 1 inch on at least one side, and will come individually bagged and labeled with name and location of occurance.

Specific Description: This obsidian is primarily black, and ranges from translucent to transparent. With some (but not all) pieces, flow banding will be observable.

Generally speaking, obsidian is a volcanic glass that forms when molten rock cools very rapidly on the surface of the earth. Because of this rapid solidification, crystals do not form. Obsidian is easily identified by not only its glassy appearance and texture, but also its unique conchoidal (resembles a shell) fracture. Additionally, the fracture produces very sharp edges, so handle with caution. Due to its favorable fracture characteristics, obsidian is often used by skilled artisans, who carefully chip it into pieces of jewelry, tools and weapons by the process known as "knapping".

Photography: The pictures are representative of the quality and general size of the specimen you will receive. None of the pieces pictured, will be the actual one you will receive, but will be from the same rock stock (outcrop or formation) your order will be filled from. Additionally, while taking the representative pictures, a diligent effort was made to capture the material in both direct sunlight and shade.
