These solid boulder opals from Queensland Australian are sooo pretty in bright aqua blue and green. They are wrapped in 18k gold on oxidized silver with a lush cluster of gemstone beads on 14k headpins. Below are two linked sky blue topaz faceted nuggets that terminate in 18k accents. Wispy chains in gold and silver drape around the topaz. The 14k posts are secured with 14k and silicon earnuts for comfort and stability. These measure 2 5/8 inches in length.
