• DETAILED DESCRIPTION

Snowflake Obsidian is a type of natural volcanic glass characterized by its distinctive appearance: white or gray snowflake-like patterns scattered within a black glassy matrix. These spots are formed by mineral crystals such as quartz or tridymite, which develop through gradual crystallization in the originally homogeneous obsidian. Formation Like common obsidian, snowflake obsidian also forms through the rapid cooling of silica-rich lava. This process creates a glassy structure lacking a crystalline lattice. Over time, some areas of the obsidian begin to crystallize, forming small spherical structures called spherulites. These mineral inclusions appear visually as white or light gray spots resembling snowflakes, hence the name Snowflake Obsidian. Characteristics Snowflake obsidian generally has a black color with prominent white or gray spots. Its hardness ranges from 5 to 5.5 on the Mohs scale. The structure is amorphous and glassy, but in some areas, it shows zones of partial crystallization. This type of obsidian is found in volcanic regions worldwide and is particularly well-known in Indonesia.
