Opalized ammonites are incredible fossils known for their iridescence. When these ancient cephalopods died, their shells were buried in sediment that prevented their transition to calcite, like many other fossils, so they eventually became a flashy form of aragonite. Opalized ammonites are biogenic gemstones (gems created living things) like amber and pearl. This unique fossil gem is said to represent ancient knowledge and connection to the cosmos.
This listing is for ONE intuitively selected opalized ammonite pair. The product photos show the variation.
Please note that as these are natural crystals, small “imperfections” such as minor chips, cracks, crevices, caves, and more may be present. Size, shape, color, pattern, etc will vary as pictured.
