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 colour of the obsidian, giving the stone its name.

Obsidian itself is formed when lava cools quickly and solidifies without crystallizing. The addition of these snowflake-like patterns distinguishes Snowflake Obsidian from other types of obsidian. The name “obsidian” is derived from the ancient Roman explorer Obsius, who is said to have discovered a similar volcanic glass in Ethiopia.

Beyond its aesthetic appeal, Snowflake Obsidian has been used for various purposes throughout history. In the realm of metaphysics and spirituality, it is believed to have grounding and protective properties.
