Solvar Sterling Silver & Connemara Marble Claddagh Drop Earrings. Treat someone special (or yourself!) with these beautiful sterling silver Claddagh earrings crafted in iconic Connemara marble, a unique stone that dates back over 900 million years and is known as “Ireland’s gemstone”. All of our Connemara is authentic, hailing from the Joyce family mine in Connemara. The Claddagh’s symbols represent love (heart), friendship (hands), and loyalty (crown). These marble drop earrings have been Irish hallmarked in Dublin Castle.
