Obsidian is a volcanic glass formed from rapidly cooled lava, and it typically lacks a layered structure like sedimentary rocks. However, variations in its composition and cooling conditions can create bands of color or inclusions, giving the appearance of layers. These bands may result from different mineral contents or gas bubbles trapped during the cooling process. The most notable types include black obsidian, snowflake obsidian, and rainbow obsidian, each showcasing unique visual characteristics.
