Snowflake Obsidian is a variation of Obsidian and is formed by rapid colling of viscous lava from volcanoes, with white patches embedded in the glass called Phenocryst. These amorphous volcanic glasses are usually black to grey-black in colors. It also occurs as red, brown-green, green, yellow, orange, and rare transparent colorless. The transparency is commonly opaque but some are found completely transparent. Air bubbles are sometimes imparted in the course of magma flow.
