AMAZONITE CRYSTAL CLUSTER
A super Amazonite Crystal Cluster. It features great crystal formation and aqua blue green colouration. Most Amazonite on the market these days is the massive, rock like type from Madagascar or Brazil, which often has a lot of iron staining and pale colour. This cluster stands out in comparison as a great collectible piece for the collector. This cluster looks much better in person and is a good size too. Amazonite is a popular mineral, which is hard to find in decent terminated clusters like this.

TOP BLACK JADE ROUGH
A grade Top Black Jade Rough 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 popular 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 the best specimen from a lot of 1000kg.
To be honest I was hoping to save this one for my self but have no time for cutting stones. The stone has three cut faces with a square corner which makes it easy to hold in a vice for diamond saw cutting. There is the expected slight green that you can see with a strong Jade torch. One face you can see is polished roughly to 3000. Some pics are with wet and dry stone to show the quality of colour and polish with great reflection. This stone is best polished with aluminium oxide then diamond to get the mirror finish. You can see the reflection of a beautiful flower in the polished window on this Jade Stone.

Cowell, South Australia, Australia.Dimensions:
28cm x 22cm x 16cm, 17500g.Jade is a name that was applied to ornamental stones that were being brought to Europe from China and Central America. It wasn’t until 1863 that it was realized that Jade was being applied to two different minerals. The two minerals are both exquisite for the purposes that jade is put to task and are hard to distinguish from each other. Now both are called Jade.

BLACK JADE SPHERE LARGE
A beautiful highly polished Black Jade Sphere. With a reflective surface like a mirror, you can see my reflection taking the photos. This is a Nephrite Black Jade Sphere from Western Australia. Jade is one of the many mineral treasures found in this vast land of Australia. These are not readily available and we never know if we can source more. It is iron impurities that adds the intense blackness to this jade. An essential for any jade or Aussie mineral collection. Great properties all round. Difficult to photograph with its highly reflective surface. Due to the very fine tight knit grain it takes one of the highest polishes of any stone. This sphere has a few characteristic white marks often visible in nephrite jade.
