Chalcedony Physical Properties.
Quartz (SiO2) is the most abundant single mineral on earth. It makes up about 12% of the earth's crust, occurring in a wide variety of igneous, metamorphic and sedimentary rocks. Quartz varieties are commonly separated into two groups based on the size of the individual grains or crystals; macrocrystalline quartz in which individual crystals are distinguishable with the naked eye, and cryptocrystalline quartz in which the individual crystals are too small to be easily distinguishable under the light microscope. The cryptocrystalline varieties of quartz may be separated into two types, fibrous and microgranular. Chalcedony is the general term applied to the fibrous cryptocrystalline varieties. Chalcedony occurs in many colours white, blue, red, green, brown or black. It is transparent to translucent, or opaque. With a white streak and it has a vitreous to waxy lustre.
