AUSSIE NEPHRITE JADE ROUGH 05
Aussie Nephrite Jade Rough 05 ready for a crafts person to carve or make jewellery with. This is genuine true nephrite jade from Cowell, South Australia (where the best Black Jade in the world comes from). 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 specimens from a lot of 1000kg. Some 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.
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. This block has two parallel cut faces and will hold easily in a vice for slabbing. Some slight hints of Chatoyant form.

Chalcedony is a variety of Quartz. A general term for all varieties of quartz that are made of microcrystalline varieties of quartz. Examples are the different types of agate, jasper, chert, chrysoprase, onyx, pietersite, etc.
Mentioned by Agricola (1546) of a stone named for the town of Chalcedon, and is a district within the city of Istanbul, Turkey.MANGANESE
MnManganese is named from a corruption of the latin word for magnestism; magnes, in allusion to its prinicple ore’s magnetic properties. Manganese crystals have yet to be found in nature, therefore it is technically not a mineral. Laboratory grown specimens can look like a natural stone.
The element manganese is an essential element in people’s daily food consumption and has several industrial uses. Manganese is used in steel alloys to increase many favorable characteristics such as strength, hardness and durability. In fact steel can not be produced without manganese; it is an essential ingredient in the process. Manganese is also used to colour glass an amethyst colour. That is not so surprising since manganese is the trace element responsible for quartz’s purple variety, amethyst.
Manganese colouring ability in minerals is well known and appreciated. Manganese is chiefly responsible for the wonderful colours in rhodochrosite, purpurite, rhodonite, serandite and spessartine to name a few. Unfortunately most manganese oxide minerals tend to be black. Manganese is extracted from the ore minerals of pyrolusite and rhodochrosite. Manganese nodules on the sea floor may one day provide an economic ore source.
