Quick Overview
This Cleoniceras Ammonite has been polished on both sides to bring out its beautiful red and green flash. This fantastic specimen actually displays a range of different colors including hints of yellows and purple.
It's difficult to photograph these highly reflective Ammonites in order to capture their colors. But we were fairly successful.
Please note, these unusual specimens will exhibit different colors when struck by light at different angles.

More Information:
Ammonites are an extinct group of marine animals in the Cephalopoda class. They were invertebrates and were more closely related to coleoids, (squids, octopus, and cuttlefish) than they were to shelled chambered Nautilus, even though they looked much more similar to the later.
The name Ammonite was derived from "ammonis cornua", translated to mean; Horns of Ammon. Ammon was an Egyptian god that was typically depicted wearing rams horns.
Cleoniceras Ammonites may sometimes display what is referred to as; red flash, opalized, or iridescent colors. The unusual coloration of these Ammonites is caused by light passing through layers of aragonite and conchiolin built up in the animal during its life cycle, then preserved through fossilization. Some Ammonites in areas of North America have been discovered with such magnificent coloration to their shells they are referred to as "Ammolite". Ammolite is considered a gem and is quite valuable to both collectors and in the jewelry industry.
