St Martin's extra large cowrie - solid 9ct goldThis is the largest cowrie we have ever had in our collection quite possibly the largest Scilly cowrie we've ever seen. It was found by a family down on the flats in front of the workshop during a shell hunting session one very low tide. The cowrie is 13. 5mm long and 10mm wide. It hangs on a solid 9ct yellow gold jump ring, this is hallmarked
