Yowah is about 1,000 kilometres from Brisbane and 130 km west of Cunnamulla and is famous for its Yowah nut opal
These are formed as matrix in a nut and can have incredible fire colours .Some opal fields do find lot nut and you can see bucket full at miners camp where they have cracked open these nuts by hand with pick or sharp instrument but miner can go through thousand s nuts and not find any with colour
In one Yowah opal festival friend bought bucket that was for charity for $600.the bucket was 4 gallon and had thousand nuts and he only found few with colour and no gem ones
These nuts are prized by collectors all over the world but most are only small have a spherical or ellipsoidal shape, the nut is ironstone as are most boulder opal fields in Queensland. But the kernel has beautiful crystal opal formed inside and not sure how mother nature created these incredible nuts.
The slabs offered have dense ironstone is beautiful patterns and the darker coloured ironstone polishes really good a s the lighter brown is porous and hard to polish
