rainbow fossil for sale

A fossilized ammonite from Alberta will soon go onto the auction block at Christie’s, for $68,000. What’s so special about it? It’s rainbow-tinted. Completely 100% natural.

The rainbow effect occured when the shell substance turned into a mineral called aragonite.

“The conditions that produce this phenomena have only been found in the Bearpaw formation in Southern Alberta (Canada).”

The one pictured is actually smaller than the biggest one going up for bid on April 7th, with the larger expected to fetch well over $100k.

It’s like the ultimate mother-of-pearl. What’s amazing is nobody made this, it’s just that pretty due to natural causes.
