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!

BLACK JADE NEPHRITE SLAB THIN
Good Black Jade Nephrite Slab Thin. Polishes to a very high luster, which is perfect for creating stunning quality Black Jade mirror finish jewellery and pendants. It was an exercise to see how thin a saw could cut the Jade. 2mm down to next to nothing in thickness 0.8mm. This material will polish to a stunning black luster. Nephrite Jade is the toughest of all naturally occurring materials. Nephrite Jade has been used from ancient times as jewellery, tools and weapons. This particular Slab is Top grade and the blackest of black jade – basically the best you can get. I believe it was mined in the 1970’s from Cowell.
