Vesicular Basalt Igneous Rock - 2 Pieces of Scoria
Obsidian is typically dark in appearance with slight color variations depending on the presence of impurities. With the inclusion, or trapping, of white, radially clustered crystals of cristobalite within the gas bubbles that were present within the obsidian when it cooled, the black glass acquires a blotchy, snowflake-style pattern from where Snowflake Obsidian takes its name. Each piece measures approximately 1.25 x 1.25 inches.
