Beautiful Iridescent Heart - Ammolite Heart

An iridescent ammolite heart from Canada, Alberta. The piece of jewelry uses the shell of a Placenticeras ammonite, a genus that lived in the Western Interior Seaway during the Late Cretaceous period (75-65 million years ago).

The Western Interior Seaway was a shallow inland sea that divided most of North America during the Late Cretaceous. Placenticeras ammonites were the dominant cephalopod genus in this sea; their shells are now recovered from the Bearpaw sediment deposits in Alberta.

The aragonite shell iridescence was created by geological pressure over 70 million years. The original nacreous inner layer was transformed into the thin, iridescent lamellar structure that characterizes ammolite.

The heart-shaped carving is a classic jewelry tradition.

A Canadian collectible with Placenticeras paleontology and Western Interior Seaway provenance.
