This scintillating stone with its display of colours, is mostly found in Australia. It is mined close to the surface under very difficult conditions of intense heat and very remote surroundings. The finest black opals come from Lightening Ridge, and other sources of this fabulous gemstone are Andamooka, Queensland and New South Wales. Opal is now popular than ever. Being the birthstone of October it symbolises confidence and faithfulness. Considered to be the most powerful and positive of gemstones, opal has a most elusive quality in its ever-changing vivacious and iridescent shimmering colours.
