Buy Koroit Opal Rough

Buy Koroit Opal Rough online direct from the mines at wholesale prices. Opal Auctions has all hundreds of types of Koroit Rough Opal from slabs to pre shaped rubs to rough rocks These opal fields were discovered in 1897 and rough is popular with cutters all over the world due to its unique ironstone patterns and its matrix opal Nearest township of Cunnamulla is 80 kms away and town of Yowah is over hours drive so many parcels do get mixed in these opal fields a s they are similar but Yowah has the famous Yowah nut. Rough parcels do seem to g et mixed between these towns but both have good reputation and rough is similar and colours are imbedded in veins so with rough you have to decide to slab on side or follow vein and see fi you can cut a cabochon stone with opal colours Parcel lots rough slabs are good value and the darker the ironstone the better the polish and the lighter colour is softer and does not polishes as good. Make sure you have lot water when polishing on wheels. Some cutters use dry method but they have state of the art air extraction systems more than just vacuum cleaner set up. For dry polishing I have seen just car pistons with sand paper on top held with contact glue and cutter can get into groves lot easier than if using polishing wheels The sandpaper doesn’t last long but is easy t o change to next grade sandpaper till polish completed But do not use dry method if you do not have good air extractor a sit is not healthy to do so. And always wear mask,not standard cheap one but filtered mask if dry polishing
