There are many myths surrounding the rock from it being the third most magnetic points on the planet, to the Bermuda triangle of the Mediterranean, to the home to the Sirens of Greek mythology, to the birthplace of the Phoenician goddess Tanit. But whatever woo woo story you want to believe there is something special about watching a sunset from one of Ibizas coves or cliffs over this powerful rock, it mysteriously lifts your spirits and recharges you, making it a sunset you will never forget. Zamak is an alloy blend of zinc, aluminium, magnesium and copper which makes it suitable for sensitive skin types, very durable and great for silver and gold plating. These earring bases were made to order on the beautiful Belearic Island of Menorca by a family run studio that started back in 1945. The 2 micron 18k gold and sterling silver plating is done by another long standing Spanish family business from Cordoba.
