Boulder Opal is formed in Ironstone and in veins of colour bars. This Ironstone can be sandy in composition to deep consolidated dark brown ironstone.

This rough boulder opal is also formed in rocks and pancake shaped rocks that need to be split open so that they can be cut and polished into stones. Most opal miners crack open a rock to expose any colour so that they can ask a greater price for the rock. It’s worth noting that not all rocks have colour. It takes a lot of work to mine the rock in the first place and then sometimes miners can crack open a rock with a hammer and find no colour. It can sometimes be a game of luck for the miners. Once colour is found the miner will ‘slab’ the opal bearing rock.

Ovaj grubi opal kamenja također se formira u stijenama i stijenama u obliku palačinke koje je potrebno rastaviti tako da se mogu rezati i polirati u kamenje. Većina rudara s opala otvori kamen kako bi razotkrila bilo koju boju kako bi mogli tražiti veću cijenu za kamen. Važno je napomenuti da sve stijene nemaju boju. Potrebno je puno rada da bi se stijena premjestila, a onda ponekad rudari mogu otvoriti kamen čekićem i ne pronaći boju. To ponekad može biti igra sreće za rudare. Nakon što se nađe boja, rudar će 'zasjeniti' stijenu opalnog ležaja.

  4. Ako se stijena ne razdvoji, uzmite čekić i pogon vijaka ili tupi rub i udarite uzduž pile, a stijena će se otvoriti otkrivajući traku boje.
