Snowflake Obsidian is a type of volcanic glass that is primarily composed of silicon dioxide, with distinctive white or grayish “snowflake” patterns dispersed throughout its black or dark brown background. This unique appearance is caused by the presence of internal crystallites or phenocrysts, typically made of the mineral cristobalite. These white snowflake-like inclusions create a striking contrast against the dark base color of the obsidian, giving the stone its name. Pics taken with an iphone and LED lighting.
