Mineral Facts

Obsidian is a volcanic rock that forms when lava solidifies so quickly that surrounding minerals have no time to crystallize. For example, the lava may flow into a lake or ocean and solidify immediately!

Obsidian is harder than glass, a 5-6 on the Mohs Scale of Hardness, and has a Conchoidal fracture (breaks like glass), so it was popularly used to form razor sharp edges to create weapons, tools, ornaments. Its reflective surface made it popular as a mirror and scrying ball. Scrying is a type of divination where the scryer gazes into the surface of the crystal to obtain images to answer their questions.

Obsidian is still used today as chess pieces, piano keys and even for surgery. Obsidian is sharper than the surgical scalpel, so it was used for precision work in cardiac surgery, cosmetic surgery and eye surgery.

Some places where Obsidian can be found include Iceland, Italy, Japan, Ecuador, Indonesia, Mexico, Hungary, Oregon and Obsidian Cliff Yellowstone Wyoming.

Personal Experience

I have used Rainbow Obsidian extensively. I learned my lesson the first time I did some official Crystal Healing Sessions. I did three clients in a row and forgot to protect myself with Obsidian. I was weak and sick for the whole week after! I have never forgotten it since! I like to wear Obsidian while doing healings, when I am going to encounter negative and draining personalities or just for the look and feel of it. I used to wear it a lot when working at the front desk as a library clerk and would have to deal with cranky patrons and their complaints about fees, so I always recommend it to anyone in customer service and especially those who work in hospitals, where a lot of sickness and spirits are flowing freely!


The more brilliant the colors, the higher the value of the stone to the wearer. Obsidian comes in all kinds of jewelry. Rainbow Obsidian jewelry is one of our top selling crystals at I Dig Crystals.
