Ammolite is a rare gemstone derived from fossil ammonites that went extinct 65 million years ago. It is found in the Bearpaw formation in Alberta, Canada. Each ammolite is unique, with colours and patterns, making it a fascinating piece.
After existing for 330 million years, ammonites became extinct along with the dinosaurs. Their fossils lay buried in the ocean sediment for millions more years before they were discovered.
The Blackfeet tribe had long been familiar with ammolite before it came into use as a gemstone. It was first described and documented by scientists in the early 1900s, and ammolite was first introduced as a gemstone in the 1960s. In 1981, ammolite was recognised as a gemstone by the World Jewellery Confederation; in 2022, ammolite was honoured as Alberta’s official gemstone.
Gemstones are beautiful, enchanting time capsules of history, and ammonites are fascinating, wearable pieces of natural history.
