This elegant cufflinks become the objects of worship by the yuppie men

If you suspect that a mixture of synthetic spinel, the easiest method is to immerse the entire piece of jewelry diiodomethane, due to a refractive index of methyl iodide and synthetic spinel very approximate the jewelery immersion artificial spinel opinion, seems to disappear, while the real diamond in the liquid is extremely obvious. This method is also particularly used to quickly distinguish between a large number of scattered particles gemstone cufflinks. Due to the fine workmanship and precious materials, the cufflinks as good as jewelry will be careful to be collected while they are used. Diiodomethane, available water instead. The outline of the synthetic spinel in the water become blurred, while the real diamond is extremely clear. Points has considerable experience in areas of red spinel and ruby cufflinks to the naked eye to identify.
Spinel have better transparency, but the lower refractive index than the ruby cufflinks, has been pondering head than ruby cufflinks, uniform color, do not have the pleochroism characteristic pleochroism of ruby cufflinks, the naked eye Able to recognize, and often hexagonal ribbon. Red the Han spar with red garnet is the difference between the refractive index of red garnet is generally higher than the upper limit of the red spinel, no fluorescence under ultraviolet light. There is no nobility in this era, so let this elegant cufflinks become the objects of worship by the yuppie men.
Beautiful, transparent crystal, crystal give the impression that the deep and good impression. Ancient China, said crystal water fine, Shuiyu Millennium ice. book reads: "Undine pass for this crystal. Ancient name Shuiyu. Mountains and Seas, often tribunal Hill Shuiyu GuoPu Note said Shuiyu Undine". This is the source of the name of Crystal. Crystal hardness, hardness (H) 7. The specific gravity of about 2.65. The melting point of 1713 ℃. Fracture conchoidal, was the oil sheen. Crystal mask shiny glass. The crystal is a hexagonal system, often has a beautiful columnar crystals produced in the geode. cufflinks, though small, can have ever-changing style, in addition to the traditional round and square. Natural crystal in addition to impurities containing inclusions. Inclusions, gaseous, liquid and solid.
Solid inclusions of mica, tourmaline, hornblende, actinolite, asbestos, feldspar, rutile, fluorite, garnet, etc.. Occasionally see in the crystal beautiful golden red hair crystal, was hailed as Venus hair, this crystal is very precious and rare. Sometimes contain asbestos and other conditions such as scratching inclusions in the crystal, the formation of the flash, and color-changing crystal, and some, like the eyes of a cat or a tiger, known as crystal opal or crystal tiger eye stone. Crystal containing gas, fluid inclusions more the interesting. There are shapes of cufflinks like water droplets, screw thread, Chinese knots and other shapes. Was measured by liquid water in the crystal is heavy water. Containing a crystal of the liquid water inclusions, commonly known as "water tank Crystal". Is considered to be a rare treasure.
Collection in the Geological Museum of China in Beijing, the fist big water tank crystal, there are about 3 cm in diameter water tank. Water tank crystal water, bold as well, is the carving of precious materials. The crystal can be divided into the following: White Crystal pure crystal is a transparent white crystal. Foreigners often like to do with it cheap jewelry, like earrings, rings and the like. Our people like to do the fan fall, stamps, paperweights. Carved Avalokitesvara, especially. Existing in the world's largest crystal ball in Washington DC to the Smithsonian Sunia Museum. German like crystal carved petals or leaves, carved and then frosted, set into earrings or pins, very beautiful. The patterns of the cufflinks also show much diversity, such as totem, flag, tai chi, steering wheel, fruit, cartoons, zodiac, constellations and other kinds of designs.
