Quartz is a hard crystalline mineral which is found abundantly all over the Earth in a variety of forms. It is the most common mineral on Earth, making up 12% of the Earth's crust by volume, and is used in a wide variety of applications including jewellery, scientific research, manufacturing, and building. Because of its many uses, quartz is also a very important mineral, and some rare varieties of quartz are considered to be quite valuable. It can also be quite beautiful, especially when cut and polished by a jeweller who appreciates the properties of quartz. It is often used as a cheaper substitute for fancier gems, and when handled well, it can be difficult to distinguish from more expensive counterparts.
Silicon dioxide is the proper chemical name for quartz, which acquires different colours and properties depending on how it was formed. Commonly, quartz takes on impurities which cause it to be collared, as is the case with the quartz forms amethyst, citrine, and rose quartz. In these instances, the crystalline structure of the quartz is readily visible, and the stone can sometimes form very large clusters of distinctive crystals. These quartzes also tend to be clear, although they may have small inclusions or areas of fracture.
In other instances, the quartz crystals are too small to see with the naked eye. This form of quartz is opaque, and sometimes called milky quartz or chalcedony. Chalcedony is quartz which has formed through deposits of layers of colored material, such as agate, jasper, and carnelian. Quartz can also appear mixed in with other geologic material, as is the case with granite and sandstone. Because quartz does not dissolve readily in water, concentrations of it tend to increase as other rocks wear away, living mixed rocks with a high percentage of quartz in their composition.
How Quartz is manufactured
First this mixture is compacted into slabs by a special vacuum and vibration process at a pressure of 100 Tons.
The slabs are then moved into a curing kiln until they assume true stone properties - but with greater performance and higher resistance to stains and impact.
When the casting process is completed, the slabs are gauged, calibrated and polished to a high and enduring shine.
