Large Ammolite Gem Ammonite Shell

This stunning double-sided rainbow Ammolite specimen is a shell from a rare and ancient Ammonite, dating back approximately 70 million years. When tilted in the light, an array of colors can be seen, ranging from greens and golds to reds and even the highly coveted and rare color, blue. The large size, incredible color and amazing detail of this specimen makes it a true collectors piece. You can see the original ridge-line / keel of the Ammonite and observe large portions of the shell on either side.  The exquisite quality of these Ammonite shells have earned it the classification of Ammolite gemstone, the perfect mix of both mineral and fossil specimen. This natural wonder occurs due to mineralization during the fossilization process, creating a rainbow of colors within the shell. Discovered in Alberta, Canada, this specimen has been gently polished and coated to maintain its stunning beauty. Natural undulations in the shell can still be seen on the surface of the stone
