Lightning Ridge in New South Wales, Australia is the world's only significant commercial source of black opal - the rarest and most valuable form of opal. Premium quality semi-black and crystal opal is also found in this area. Mining commenced in 1902 and it continues today on approximately two hundred distinct opal fields.
Crystal opal with intense colorplay visible throughout. Faces beautifully
for a unique ring or pendant. Minor sand spots left on back to preserve color.
Blue/green crystal in a captivating shape. Flashy color in a large face would make
a very nice pendant. This stone could also be set in a well-protected ring.
Dark crystal (see light shining through in slideshow) with directional sheets
of blue rolling across the face. Also glimmers of green and red.
Perfect ring stone in a calibrated shape with a very interesting pattern sure to
draw attention. The black potch also leaves no doubt it's Lightning Ridge opal.
Very cool picture stone with bright glittery blues and greens enhanced even more
by the contrast with the highly polished jet-black potch.
Really interesting yin/yang picture stone. Swirly gray potch with green flashes
curled around black potch that has a subtle deep blue glow within it.
