Semi-Black Opals

Also known as dark opal and grey opal, semi-black opal refers to opals which have a darker body tone than white opals, yet are not quite dark enough to be classified as black opals. The body tone of these stones falls in either the N5 or N6 category in the above tone chart diagram. Semi black opals are found mostly at Lightning Ridge, however they have also been found at Mintabie in South Australia. To give a rough idea, top quality semi-black opal can fetch prices up to $3,500 per carat.
