Tea crystal is divided into tea, ink and smoke according to the depth of color. This is also something that everyone should pay attention to. When others ask to know that they are all three kinds, they are collectively called sapphire. Tea crystal SmokyQuartz (BrownQuartz), also known as smoke crystal, ink crystal, is radioactive, energy is hidden. Most of the tea crystals are hexagonal cylinders. Like other clear crystals, there are sometimes ice cracks, clouds and so on. The color of the sapphire is different, some are light brown or dark brown, but sometimes it will be completely opaque black brown. The color of the citrine is different because it is affected by natural radiation during the formation. 1. Chemical composition: Silica, the chemical composition contains Si-46.7%, O-53.3%. Multiple colors appear due to the inclusion of different blends. Purple and green are colored by iron (Fe2+) ions, purple can also be caused by titanium (Ti4+), and other colors are colored by color centers. 2, associated mineral composition: goethite, hematite, rutile, magnetite, garnet, chlorite and other inclusions; hair crystals contain macroscopic inclusions of hair-like needle-like minerals. Those containing manganese and iron are called amethyst; those with iron (gold or yellow) are called citrine; those with manganese and titanium are called rose quartz, which is called pink crystal; those with smoke are called smoke crystal; those of brown are called brown crystal. Tea crystal; black transparent is called ink crystal. 3, structure: crystal crystal crystal is a trigonal system, often hexagonal column, the column is a pointed or two pointed, a number of long columns connected together, known as crystal clusters, beautiful and spectacular, the shape can be described as Various poses. 4, crystal specific gravity: 2.56-2.66 g / cm3. This means that the weight of a certain volume of crystal is 2.56-2.66 times the weight of the same volume of water. The density of the block variant crystal may be slightly higher.
