A Lithicoin is a specially polished slice of stone. They measure about 33mm in diameter and are set in a solid 14k Yellow Gold 4 Prong Coinmount Pendant Setting. Chain sold seperately, we recommend the Solid 14k 1.5mm Bead Chain. Wear with care, as these lithicoins can be fragile! One of a kind, when it's sold it's gone.
