This 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.
