Quartz is the main component of the stone is a chemical compound consisting of one molecule of silicon and two molecules of oxygen. It represents silicon dioxide (SiO2). It is also one of the most abundant minerals on the surface of the earth, and it has unique properties that made it one of the most used natural materials in many fields.
Quartz is the most abundant and most common mineral on the Earth. It is found in almost every geological environment and also it is at least a component of almost every rock type. It has a hexagonal crystal structure and is made of trigonal crystallized silica. It is most varied in terms of varieties, colors and forms. The most important distinction between the types of quartz is that one is of macrocrystalline, which is individual crystal visible to the unaided eye, and the other is microcrystalline or cryptodrystalline varieties, aggregates of crystals visible only under high magnification. Chalcedony is the generic term for cryptocrystalline quartz. The transparent variety tends to be macrocrystalline and the cryptocrystalline varieties are either translucent or mostly opaque. Salient Features Clear (in pure form) 6-sided prism ending in 6-sided pyramid (typical) It has a hardness of seven on the Mohs Scale which makes it very durable.
Quartz is the second most abundant mineral in the Earth's continental crust, after feldspar. Its crystal structure is a continuous framework of SiO4 siliconoxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2.
Quartz is a mineral composed of silicon and oxygen, with a chemical composition of SiO2. It is the most abundant mineral in Earth's crust and is resistant to both chemical and physical weathering.
Sri Lanka is famous throughout the world for the exquisite mineral varieties of very high purity. Among them vein quartz too holds prime importance. The material, generally known as quartz is primarily made of silicon and oxygen (silica-SiO2) and is considered one of the most abundant minerals found in the Earth's crust.

The onix or onyx is a type of chalcedony of the family of quartz that can be found in black and white, or gray. Also known as, marble onyx, with chemical representation SiO2, is composed of silicon or silicon oxide and reaches a hardness of 7 on the scale of mosh. Its formation is volcanic, caused by the accumulation of volcanic gases. It is used mainly for jewelry and decorative items, for the attractiveness of its greenish tones, and for the quality of its polish. Onyx is strength - giving. It provides support in difficult or confusing circumstances and during times of enormous mental or physical stress. Centering your energy and aligning it with a higher power, accessing higher guidance, is facilitated by Onyx as is connection with the whole.
