BOULDER OPAL SLAB
A rare rough Queensland Boulder Opal Slab. You never get unworked pieces like this for sale, so this really is a gem in the rough. Features ethereal streaks of green, purple, blue and pink on a white background, wrapped in its sandstone host rock. Two photos are taken against the sun to show transparency. Being unpolished it was dang near impossible to photograph the colour streaks in this piece, in any light. I’ve done my best but it does look so much better in person. Polished up of course it will look absolutely stunning. A great project for the lapidary or opal enthusiast or jeweller. A super piece!

TOP BOULDER OPAL ROUGH PARCEL
Check out this outstanding Top Boulder Opal Rough Parcel. An extra quality parcel of beautiful rough Boulder Opal. These are the best specimens out of several lots bought in person directly from the dude that mined it! Unusual and vibrant aqua colouring is a feature of this lot, along with blue, green sparkles and other flashes of colour. Some pieces show the veining which is an attractive feature also. Each piece has been cut to its best potential ready for jewellery or perfect as a mineral specimen in your Aussie collection. I feel like this one is a parcel I’ll regret selling, but that’s the way it goes in the rock trade. I love opal in the rough and this is a special little parcel on offer. Most photos taken wet, none do justice to this lot, which looks better in person. Boulder Opal is found only in Australia, making it rare gem indeed. Enjoy!
