A BEAUTIFUL and RARE PIECE OF MOTHER EARTH -
A ENGAGING PIECE OF OBSIDIAN  IS A WONDERFUL SPECIMEN OF WHAT THE EARTH HAS GIVEN TO US.
.
For centuries this material has been produced when lava is extruded from a volcanic cooling rapidly with a minimum of crystal growth.  The volcanic flows have a high content of silica.  This high viscosity of atomic diffusion and together with  the rapid cooling, this results in a natural glass from the lava, its parent material.
This dense mineral- stone is hard, brittle, and amorphous, it therefore fractures with sharp edges.  In the past it was used to manufacture cutting and piercing tools, and at one time was experimentally used as surgical scapel blades. Obsidian is mineral-like, but not a true mineral because as a glass it is not crystalline; additionally its composition is too variable to be truly classified as a mineral.
In it pure form it is usually dark in appearance, though colors may vary depending on the impurities present, i.e., iron may give dark brown, to black, other inclusions of small white clusters may give a snowflake pattern.  Others may appear golden, rainbow (from Mexico), striped.  Other areas are Argentina, Canada, Italy, and western U.S., including AZ, CO, TX, and UT.  Obsidian was often used in religious ceremonies.
