THIS BLACK OPAL IS A UNIQUE BEAUTY. IT HAS WHAT WE CALL A PEACOCK PATTERN. THIS IS BECAUSE THE OPAL CONSISTS OF MAINLY GREEN AND BLUE COLOUR PLAY. IT PICKS UP THE ODD RED OR ORANGE SPOT AT CERTAIN ANGLES BUT THEY ARE NOT WORTH MENTIONING. THE GEM HAS 360 DEGREES COLOUR PLAY.

Black opals are the most valuable form of opal - due to their dark body tone and the resulting vibrant play of colour. Top of the range gem quality black opal can fetch prices up to AUD $15,000 per carat. However, just because an opal is black doesn't make it valuable. There are many factors including brightness and pattern which determine the over all value of opal.
Australia is the classical Opal country and today is the worldwide most important supplier of Fine Opals. Almost 95 per cent of all Opals come from Australian mines.
Lightning Ridge in New South Wales, is the main source of black opal, opal containing a predominantly dark background. Mintabie is another source of the black opal.
