The cufflinks can not only to break the dull atmosphere

How to identify gems hardness and toughness? Hardness: the hardness of minerals is a mineral to resist external mechanical action (such as: characterization, push, grind) the ability to invade. Hardness, there are two metrics: the relative hardness of precious stones, gem hardness anisotropy, mean the same in different directions on the sapphire crystal, the crystal structure and hardness vary in different phenomena. Typically, when international top brands introduce the men dress in the new season will also release new cufflinks to complement each other. Toughness: Toughness is also known to combat hardness, resistance to crushing stones refers to (wear and tear, stretch, push, cut) capability, it is difficult for the broken nature of the toughness, brittle easily broken, said the nature. Common gem toughness from strong to weak: black diamonds, jade, jadeite, rubies, sapphires, diamonds, crystal, aquamarine, peridot, emerald, topaz, moonstones, gold emerald, fluorite hardness.
The gem stones are not necessarily robust, although its absolute hardness may be enormous, like a diamond is hard and brittle. Some limited edition cufflinks, apart from decorating the clothing in the same time, are also rare items for the collectors. Gemology in the color of the stones how to divide? Optical theory to explain gems gray, black, white, colored, colorless, and other colors. Classification of natural color gem: self-colored gem stones from the color mainly by the chemical composition and crystal structure characteristics of the decision. For example: ruby, sapphire, like structure, like chemical composition, color-causing ions to produce a different color. he colored stones: colorless when pure, its color is its chemical composition does not constitute a major part of the trace elements due to the color of the gem.
 Such as: ruby, tourmaline, emerald false-color gem: gem is due to certain geometrical optics and physical optics causes. Such as: diamond by color, change color opal, moonstone effect, Venus effect, stars and cat's eye effect, change color elongated stone, quartz iridescence. In the road of revival of men’s accessories, cuff links definitely is a pivotal role.  White, colorless, black, gray explanation: white, colorless basically all light absorption. Black, gray  objects of various wavelengths of white light is absorbed by the same degree of uniformity. Color-causing elements: Most stones contain too light can cause color caused by selective absorption of elements that are common in eight kinds of precious ingredients transition group elements: color-causing elements in the table in addition to gem color-causing elements, color stones also may be caused by The following factors.
Dispersion is the white light into its component colors (wavelengths) of the phenomenon, commonly white with a glass prism to break down. Interference and Diffraction: see some of the colors or stones from the interference effect caused by, or due to diffraction effects caused.  For example: Moonstone, Opal. The cufflinks can not only to break the dull atmosphere. Classification of gem color from the color, his color and false color, how to divide? Classification of natural color gem: self-colored gem stones from the color mainly by the chemical composition and crystal structure characteristics of the decision. For example, to produce a different sub-colors. he colorless when pure color gems, its color is its chemical composition does not constitute a major part of the trace elements due to the color of the gem.
Such as: gem, tourmaline, emerald false-color gem ruby, sapphire, like structure, chemical composition, like color caused from the definition: gem is due to certain geometrical optics and physical optics causes. The mens cufflinks are also direct a secret channel for men’s taste. Such as: diamond by color, change color opal, moonstone effect, Venus effect, stars and cat's eye effect, change color elongated stone, quartz iridescence.  How to distinguish between the fluorescence and phosphorescence gem, how precious the fluorescence and phosphorescence phenomena identification of gemstones? Luminescence is the jewel in the external reflection high-energy radiation under the influence of the nature of visible light. Fluorescent: refers to the jewel in the high-energy ray irradiation of visible light emission phenomenon.
