This Boulder Opal pair sparkle with gorgeous aqua green colours, they have that magical way of changing colour as the light catches them. These opal earrings have been made from a natural split. We split one vein of opal to create a mirror image …a matching pair.  The earrings are set with anti tarnish sterling silver in a drop from a hook style and are 32mm in entire length with the opals alone measuring 15mm x 5mm.
