This ammonite is the first piece I ever cast. My search for an ammonite pendant wasn't coming up with what I was looking for. Whilst walking along the Jurassic Coast at Charmouth in Dorset I found this Promicroceras Ammonite. After being cleaned up and cast in sterling silver, the hole in the middle meant that I could wear it on a cord. It is a really tactile object that it over 200 million years old! Measuring 1.5cm across, the oxidised finish gives the piece an aged look. The thong allows for the ammonite to be worn at a range of lengths.
