An opalescent Ammolite heart with dominant blue iridescence from Canada, Alberta. The heart-shaped sculpture utilizes the natural aragonite shell of a Cretaceous ammonite as raw material.
Ammolite is the opalescent variety of the original aragonite shell (CaCO₃) of Placenticeras ammonites from the Bearpaw Formation. Geological pressure and temperature over 70 million years transformed the shell into an iridescent layer of microscopic aragonite lamellae.
The blue iridescence of this piece indicates particularly thin aragonite lamellae (approx. 400-500 nanometers); at these layer thicknesses, blue light is diffracted most strongly. Thin lamellae produce blue colors, while thick ones produce red.
The heart-shaped sculptural processing follows the traditional jewelry tradition of Canadian workshops. The polished exterior brings out the full iridescence.
A Canadian collector's item with documented Bearpaw Cretaceous provenance and gemologically classified blue iridescence premium.
