Large Septarian Pendant in Sterling Silver
A slightly larger but not overly chunky septarian pendant designed in a fine sterling silver setting.
Septarian is an interesting rock composed of yellow calcite crystals and the minerals aragonite and limestone.
Septarian, correctly known as a septarian nodule, formed during the Cretaceous Period, which began approximately 145 million years ago and ended around the time dinosaurs disappeared.
The nodules formed beneath the water as minerals and organic matter accumulated around a centre mass. Gradually, over several million years and with the help of various geological processes, the mass hardened and cemented together to form a nodule.
This septarian gemstone has been polished to a vitreous lustre, so it reflects light in a similar way to glass.
