Sea Shell
A sea shell - specifically, (after a good deal of research and until proven otherwise) a small Pleuroploca gigantea, commonly called the Horse Conch. Its spiral, viewed from above is a beautiful example of Leonardo Fibonacci's theorem - that after two starting numbers, each number is equal to the sum of the two preceding numbers. Comes with free sound of the sea - no batteries required.
Size: 6.1/2" x 3"
Some loss to the outer edge of the lip, but otherwise good.
£15.00 - plus P & P.
