These unique Boulder Opal earrings have a organic flowing pattern with caramel and vanilla opal colours . The natural formation allows us to create gorgeous unique shaped opal jewellery.   The earrings have been made from a natural split. We split one vein of opal to create a mirror image …a matching pair.  They are set with high quality anti tarnish sterling silver and measure 35mm in entire length with the opals alone measuring 20mm x 10mm.
