Large and distinctive septarian pendant crafted by hand in a fine sterling silver setting. Septarian cabochons of this size are rarely seen in jewellery but it's a stone that we love to use and the larger pieces certainly make a statement.
This popular lapidary material is made up partly of clay therefore gemstones can sometimes be slightly heavier than other cabochons of a similar size. With that said, we're aware that nobody wants to wear a heavy stone around their neck so the pieces that we feature in our collection have all been very carefully chosen.
This highly polished septarian gemstone boasts slightly translucent yellow calcite crystals alongside the mineral aragonite and limestone. Septarian is a kind of prehistoric mud ball that's known to have formed during the Cretaceous Period which started around 145 million years ago. Also known as a septarian nodule or concretion, these curious structures continue to frustrate geologists because certain aspects relating to exactly how they formed is still not fully understood.
