A slice of Sodalite from Namibia polished and mounted in a four prong back solid 14k gold coin mounting. The pendant hangs on an 18" solid 14k yellow gold 1.5mm bead chain with lobster clasp as pictured. The pendant is about 33mm in diameter. Wear with care, as these lithicoins can be fragile! One of a kind, when it's sold it's gone.
