These colorful ammolite mosaic cabochon's are all the best parts of ammolite shells fused together into one piece. 

Ammolite is an opal-like organic gemstone made of the fossilized shells of ammonites, a group of extinct marine mollusc animals. This organic gemstone has a dazzling range of colors and patterns and is highly desired for freeform natural cabochons and assembled jewelry pieces.

It is found primarily along the eastern slopes of the Rocky Mountains of North America in the Bearpaw Formation that extends from Alberta to Saskatchewan in Canada and south to Montana in the USA. 

Ammolite can come in any color in the rainbow but most are green and red. Blue and violet are rare and, typically, more valuable.

Ammonite was named after the Ancient Egyptian god Amun, who was represented with ram’s horns.
