This is an eye catching Gold Dragonfly Setting with a bright flashy Queensland Boulder Opal. The Crystal Boulder Opal shows all the colours of the rainbow in a broad fire pattern as well as a pin fire pattern. You can see the depth to the Opal as it brightly flashes green, blue, orange, yellow, and red from any angle. The flashy and colourful Boulder Opal comes from an Opal mine in the centre of Queensland, near the District of Winton. The Boulder Opal is enhanced by the 18ct Gold setting with delicate wings and abdomen so that it may be worn on a large Gold Chain (as shown) or on an Omega Chain.
