I have for sale a Large rough Lightning Ridge Opal from Australia. This superb piece weighs a hefty 76.08cts and is 42x32x16mm. It is a Light Base Seam type Opal with loads of Green/Blue/Red and Gold Fires through it, These are through the whole stone, showing on all exposed faces. There is Skin/Sand both Top and bottom. Great Specimen Gem for a collector, or Cut/Polish and see what you get. Either a huge freeform cab or a few smaller stones.  Dont come across these very often.  Grab a bargain..  Thanks for looking.  (Price is around the $11AuD/Ct mark )
