You've likely seen classic black obsidian before — but rainbow obsidian is in a league of its own. This rare volcanic glass dazzles with vibrant, shifting colours that make it one of the most sought-after crystals in the gemstone market today.
What Is Obsidian? A Natural Glass, Not a Gemstone
Technically, obsidian is not a gemstone — it's a type of natural volcanic glass formed when lava from a volcano cools rapidly. It comes in a surprising range of varieties beyond the classic black, including:
- Brown, orange, and red obsidian
- Gold sheen and silver sheen obsidian
- Green and yellow obsidian
- Rainbow obsidian (the rarest and most colourful variety)
- Snowflake obsidian (featuring white crystal patterns)
What Makes Rainbow Obsidian So Colourful?
Rainbow obsidian gets its striking iridescence from traces of an iron-rich mineral called magnetite. During volcanic cooling, magnetite nanoparticles become trapped between layers of lava. When light hits these microscopic layers, it diffracts into a full spectrum of colour — producing the signature rainbow shimmer rainbow obsidian is famous for.
Why Does Rainbow Obsidian Vary So Much in Price?
Rainbow obsidian prices can range significantly. Here are the key factors that affect its value:
- Natural vs. treated stones: Some obsidian on the market is not 100% natural. Always buy from a trusted source.
- Magnetite alignment: For the rainbow effect to appear, magnetite must align perfectly within the stone — making high-quality pieces genuinely rare.
- Stone size: Larger rainbow obsidian stones are rarer and command higher prices.
- Variety: Double rainbow eye obsidian is rarer and more valuable than single rainbow eye.
- Colour vibrancy: The more vivid and distinct the colours, the higher the value.
Rainbow Eye vs. Double Rainbow Eye Obsidian: What's the Difference?
Rainbow obsidian is further classified into two main varieties. Here's how to tell them apart:

Frequently Asked Questions About Rainbow Obsidian
Is rainbow obsidian natural?
Yes — genuine rainbow obsidian is 100% natural volcanic glass. However, some stones sold on the market are artificially treated or dyed. When purchasing, always ask for confirmation that the stone is natural, and buy from reputable sellers.
What is rainbow obsidian good for?
Rainbow obsidian is primarily used for emotional healing, grounding, and protection. It is especially helpful for people dealing with heartbreak, grief, anxiety, or energetic overwhelm. It is associated with the root chakra.
How can I tell if my rainbow obsidian is real?
Authentic rainbow obsidian will show its colours only when light hits it at a specific angle — the iridescence is subtle and directional, not uniform. Fake or dyed stones may appear uniformly colourful under any lighting. Real obsidian also feels slightly cool and glassy to the touch.
What is the difference between rainbow obsidian and black obsidian?
Both are volcanic glass. Black obsidian appears uniformly dark, while rainbow obsidian contains magnetite nanoparticles that create colourful iridescent sheens when light is reflected across the stone's surface.
Where does rainbow obsidian come from?
Rainbow obsidian is most commonly found in Mexico, where specific volcanic conditions allow for the precise magnetite alignment required to produce the rainbow effect.
