This Boulder Opal pair glow with electric blue/violet colours, they have that magical opal shimmer as they move when 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 26mm in entire length with the opals alone measuring 11mm x 8mm.
