We offer a wide selection of fossil and ammonite jewellery, making perfect gifts for geologists or palaeontologists. This video explains the difference between our different types of ammonites - Madagascan, Promicroceras and Pyrite. 

This pyritised Ammonite was collected near the Russian city of Saratov, and dates to the middle Jurassic around 160 million years ago. The chambers of the shell are filled with pyrite. These breathtakingly beautiful ammonites died in a sea that contained a heavy concentrate of iron. As the ammonite decayed, it released sulphide which reacted with the dissolved iron in the water.

The interaction of sulphide and iron formed the pyrite, which is also known as fool's gold, replacing the ammonite cell by cell. Glittering gold and grey pyrite fills the chambers, giving them the appearance of gold.
