Note: This large-size magnificent black opal has the characteristics of opal from Lightning Ridge in New South Wales, Australia, which is known to be the most famous opal mine in the world.
Black opals mined from Lightning Ridge have always had an exceptional reputation. Top quality naturally patterned opals with stunning electric peacock blue and green flashes are considered to be highly desirable.

A thick black opal of this size featuring a unique 'Ulysses Butterfly wing' pattern with such a vibrant 'play of colour' is very unusual and rare.
