Black Opal $1,200,000.00 two of the guys who found the Halley’s comet Opal were working with me on a share venture mining lease of my only a year before they passed away . The brothers found the Guinness book of records Opal gemstone because the lease was in their name . They had worked the old claim leased at lightning Ridge extensively underground conventionally for many years making an extremely good living , walking only a meter from the Guinness book of record black Opal day after day as they walked back and forward through the shaft going to work for many years. The gemstone was found at the lunatic Hill location also known by government records as the 3 mile opal . Which I would have to say is the richest field in the history of the black opal industry and the highest quality gem opal ever seen even today .
The brothers who owned the claim finally uncovered this 100 million year old black opal by getting involved with a local company that provided all the earthmoving machinery and finances to undertake such a huge open cut mine , “as I should know as I open cut the claim next to the Guinness book of record opal in 1998. When passed away it was quite a tragic and sad finished to particularly the oldest of the two brothers. The adjoining claims were named Scots, and the leaning tree claim and revolver claim, the opal Hunter claim which I open cut and still have the legal rights to mine today. These days there is a protected order over all these claims to preserve for future generations in the State of New South Wales capital city Sydney Australia . The Sydney Museum will be constructing a multimillion dollar Opal Centre at the township of lightning Ridge opposite the opal hunters claim of my and between the 3 mile flat and lunatic Hill . The Museum will have highly renowned Sydney paleontologist will have an exhibition of many rare fossils dinosaurs.
