Rainbow Obsidian: Iridescent Obsidian
Density: Rainbow obsidian is a relatively dense stone, with a density of 2.4-2.6 g/cm3. This means it feels heavier than many other common rocks of similar size.
Magnetism: Due to the presence of magnetite inclusions, rainbow obsidian is weakly magnetic. However, this magnetism is not strong enough to attract most other magnets.
Specific Gravity: Specific gravity refers to the density of a substance compared to the density of water. Rainbow obsidian's specific gravity ranges from 2.4 to 2.7, meaning it is 2.4 to 2.7 times heavier than water.
Fracture: Rainbow obsidian exhibits a conchoidal fracture, meaning it breaks into sharp, irregular fragments with curved edges. This characteristic makes it unsuitable for applications requiring high durability or impact resistance.
Refractive Index: The refractive index of rainbow obsidian varies slightly depending on its specific composition, typically ranging between 1.48 and 1.55. This property influences how light interacts with the stone and contributes to its shimmering appearance.
