Blue opalescent heart - Ammolite heart

An opalescent Ammolite heart from Canada, Alberta with a distinct blue-green iridescence color variation. The jewelry processing follows the established heart shape tradition of the Canadian Ammolite workshops in Lethbridge.

The Lethbridge region in Alberta is the global center of Ammolite processing. Here, the raw material from the Bearpaw deposits on the St. Mary River is selected, cut, stabilized, and processed into jewelry forms.

The multi-colored iridescence indicates an uneven aragonite lamella thickness across the shell surface; some areas reflect blue light, others green. This variability makes each piece unique.

The thin Ammolite layer is stabilized in a triplet sandwich: an Ammolite layer between a dark shale base and a protective quartz or spinel top layer.

A Canadian collector's item with Lethbridge craftsmanship and triplet-stabilized iridescence classification.
