I have obtained a limited supply of Whitby Jet, so these earrings are one off earrings and will be absolutely unique. The Jet is fossilised over millions of years from monkey puzzle trees, and is sporadically found on the beach. Supply is limited, and ive been lucky enough to get hold of some ! These earrings are sterling silver and polished Jet and hang at  55mm, but I can shorten wires if you prefer, just let me know.
