Pyrite Ammonite Pendant | 25mm | Fossil Necklace in Sterling Silver

A Jurassic Fossil Turned to Fool's Gold

This pendant sets a pyrite ammonite from the Ardèche region of France in sterling silver. The walls of the shell have been replaced by pyrite, giving a metallic charcoal and silvery-grey spiral that frames each chamber. Inside, the chambers are filled with honey, cream and soft gold crystals, creating a bold, almost mosaic-like pattern. The fossil keeps its natural shell shape, with a closed silver back and the bail set at the tail.

• Material: pyrite ammonite, sterling silver with closed back
• Size: approx. 25mm x 20mm
• Origin: Ardèche, France
• Free 18" sterling silver chain included

How Pyrite Ammonites Form

When this ammonite died around 150 million years ago, in the Jurassic period, it settled into oxygen-poor mud on the seabed. As it decayed, sulphur reacted with iron in the sediment and slowly replaced the shell with pyrite. In crystal lore, pyrite is linked with confidence, protection and abundance.

Fun fact: pyrite is nicknamed fool's gold because prospectors often mistook its brassy shine for real gold.

Who It Suits

• Fossil collectors looking for something different from Madagascan ammonites
• Dinosaur and Jurassic fans of any age
• Lovers of mixed-metal, monochrome jewellery

How to Wear and Care For It

The grey and silver tones suit cool colours such as black, grey, navy and white. Keep it dry and away from damp, as pyrite can dull in humid conditions.

We offer a wide selection of fossil and ammonite jewellery, and this video explains the difference between our different types of ammonites – Madagascan, Promicroceras and Pyrite.

The ammonites used to create this pyrite ammonite pendant were found in the Ardeche, France, and is estimated to date back around 150 million years.

This fossilised sea creature has been divided into two equal halves and polished to reveal the innate markings that set ammonites apart from other fossils.

The pyrite effect, also known as iron pyrite or fool's gold, produces a brassy metallic lustre. This mineralisation forms where decaying organic material consumes oxygen and releases sulphur.
