ENHYDRO QUARTZ CRYSTAL 01
Enhydro Quartz Crystal 01 for sale. Here is a stunning Enhydro with multiple inclusions of what exactly is a bit of a mystery. These moving inclusions are what looks like black carbon material inside a fluid which appears clear. There are five that I have found in this double terminated quartz crystal. Some are clusters or grouping of black material. Most are sinkers – sinkers fall down and floaters float up when turned to balance gravity.
Enhydro is the name given to a fluid or gas bubble trapped inside a crystal. These little bubbles are simply fascinating, it boggles the mind as to how it got there. The liquid inside can be water, petroleum, co2,oil or others. This Enhydro has material inside the bubble that sinks when the bubble floats up – I think it looks like carbon. Like the liquid inside could be millions of years old.

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.
