Dark opals sit between black and light on the N-scale — graded N5 or N6. They carry much of the drama of a black opal at a friendlier price, which makes them a favourite of jewellery designers and first-time collectors alike.
All stones below are natural solid Australian opal, priced and certified, with video on the stone pages. For the darkest stones see our black opals; for bright crystal material see light opals.
