CHALCOPYRITE CRYSTAL CLUSTER
CHALCOPYRITE CRYSTAL CLUSTER
A beautiful bright Chalcopyrite Crystal Cluster. This Chalcopyrite Crystal Cluster had to be removed from our shop as too many customers couldn’t help them selves and kept touching it. Eventually all metals will tarnish if people keep touching them and they will loose their shiny brightness. This is the best we have seen for a solid cluster of Chalcopyrite worthy of museum grade or serious collection. This Chalcopyrite is very shiny and reflective. Chalcopyrite is Pyrite with Copper which gives it a more realistic look of gold. A great chunky specimen which has taken millions of years for nature to produce. This specimen is mounted on a perspex pad for enhanced display.

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.
