Septarian ring

This hallmarked silver ring is set with a lovely 13.20ct Septarian cabochon.  The top of the ring measures approx. 22x18mm.  The ring is a UK size P and the band is approx. 6mm wide.   

This stone started out as a ball of mud (nice) - during the Cretaceous period these ancient mud balls dried and cracked before mineralisation occurred.  For those who like a little more detail, calcite leeched into the cracks forming calcite crystals on a layer of aragonite.  The bentonite clay surrounding this was eventually replaced with limestone turning the ball of mud to stone.  They are found in Madagascar and Utah, USA.

This piece of jewellery is hallmarked for your assurance and comes with a gift box and a gift card detailing the weight of the gemstone and a little information about it, as shown in the example photograph.  As each stone is unique and each piece of jewellery handmade, every piece of jewellery is individual and you will receive the piece of jewellery shown in these photographs.
