AMAZONITE CRYSTAL CLUSTER
AMAZONITE CRYSTAL CLUSTER
A super Amazonite Crystal Cluster. It features great, chunky crystal formation and that sought-after 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. It comes mounted on perspex for the best possible display. Amazonite is a popular mineral, which is hard to find in decent terminated clusters like this.

AMBER POLISHED
AMBER POLISHED
Amber Polished or fossil tree sap. This one has a very interesting insect in it to check out under a magnifying glass. Amber is a beautiful stone that is cut and polished and used as a valuable gemstone. It is also a fossil and can contain (this one does) preserved insects and other animals and plants that are tens of millions of years old. The odd inclusions that are often seen in amber usually add to amber’s unique look and in many cases greatly increase its value. There is a great close up of the bug inside this Amber, with good light from outside. One pic is taken under Long Wave UV light as this is fluorescent material. This particular specimen is from the private collection.

BISMUTH CRYSTAL
BISMUTH CRYSTAL
An outstanding Bismuth Crystal specimen for the connoisseur collector.
Dimensions:
5.1cm x 5.4cm x 4.1cm, 77g.Location:
Lab Grown.
BISMUTH Bi.
Bismuth is rarely found in nature in its elemental form. Of growing interest in rock shops, however, most are laboratory-grown bismuth crystals. These crystals, while not natural, are nonetheless very interesting to the mineral hobbyist and to others. The unique look that these clusters offer is really indescribable. Its colour consists of iridescent metallic yellow, blue and green hues.
Of interest to hobbyists are the pseudocubic “hopper” crystals that are always present on the laboratory produced specimens, they are not seen in but only the rarest of natural crystals. Hopper crystals are a unique crystallographic curiosity Just the edges extend outward from the center of the crystal leaving hollow stairstep faces between these edges.

BLACK JADE SPHERE
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.
