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!

AMMONITE PAIR
An awesome Large Cleoniceras Ammonite Pair. Sliced and polished to perfectly display the amazing chambers inside. The pics show some well formed calcification, crystalised pockets and dendritic formation when the sun or a torch is shone through. There is a reasonable show of irredecnce on the outside faces, hmm pretty cool specimens of high quality. This is a natural prehistoric fossil specimen, they never cease to amaze me. An amazing artifact and a close example of the Fibonacci sequence. A super and ancient gift for the natural history enthusiast. These Cleoniceras Ammonites are from the middle of the Cretaceous period which was between 145.5 and 65.5 million years ago!

TOP BLACK JADE ROUGH B+++
Top Black Jade Rough B+++ ready for a crafts person to carve or make jewellery with. This is genuine true black nephrite jade from Cowell, South Australia (the best Black Jade in the world). This variant of jade is becoming more scarce and is used, in particular, for carving into super-lustrous pendants and jewellery. One of the toughest rocks on the planet. The Black colour is from an inclusion of Iron of up to 8%. This is one of the best specimens from a lot of 1000kg. You can still see the old mine grading marks with the grade and initials of the person who graded it. When we procured this lot we were told it came out of an old rusted out container from the 70’s.
To be honest I was hoping to save this one for my self. The stone has one cut face and is flat with some colour near the rind at one end. Some pics are with wet and dry stone to show the quality of colour and reflection. This stone is best polished with aluminium oxide then diamond to get the mirror finish.
