SOLD!!! I made these gorgeous, well matched, natural, solid 6.70ct Boulder Opals from Australia into earrings for pierced ears with 14kt Rolled Gold Wire Wrapping. The boulder opals themselves measure 14x9x4mm, in their wire wrap they measure 23mm long, and from the top of the ear wire they measure 33mm long. It is rare for me to be able to find stones that match this well, so I had to make them into earrings rather than two pendants. The stones dangle freely from the curved earring wires, allowing movement to maximize their opal color flash.
