Extra large St Martin's cowrieThis is the largest cowrie we have ever had in our collection quite possibly the largest Scilly cowrie we've ever since. 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 silver jump ring. The second images shows this cowrie second in from the left. Solid 925 sterling silver
