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.

GLAUBERITE CRYSTALS
A lovely specimen of Glauberite Crystals. Initially these specimens are clear when first fished out of the mud with cut and bloodied hands. They turn white after contact with the Oxygen in the air. The fossicker who fished this one told me the second day was worse when cuts on his fingers were roughed up again. This happens when feeling around deep in the mud for them. Great fun. This is a rare and unusual Aussie mineral. The last big one found in an old box.

PYRITE SUN MEDIUM
A stunning Pyrite Sun Medium. This is a natural formation of Pyrite and something quite different to the usual more cubic looking varieties. Striations radiate out from the centre.
