These doublet opals shimmer with pink, blue and green colours; they have that magical way of changing colour as the light catches them. The earrings are set in anti tarnish sterling silver in a drop from a stud style earring. The opals alone measure 18mm long x 8mm wide, with the length of the entire earring measuring 27mm. The earrings have been made from a natural split; we split one vein of opal to create a mirror image…. a matching pair.
