Rainbow and black Obsidian Tumbled Stones,
Identification and Characteristics
Rainbow Obsidian is a naturally occurring volcanic glass that appears solid black or deep brown until it is held under bright light at certain angles. This effect, often called "sheen" or "shimmer," reveals hidden bands of colors such as green, purple, blue, or gold.
Formation: It is formed when molten lava cools so quickly that it cannot crystallize, with microscopic inclusions of water or minerals creating the distinctive rainbow effect.
Varieties: While often called "Rainbow Obsidian," similar-looking stones may be labeled as Platinum Obsidian or Velvet Sheen Obsidian depending on the specific intensity and hue of their iridescence.
