The lack of light colored diamond cufflinks

Identification method, zircon as a very polarizing and birefringence, when observed with 10 times the magnifying glass after processing edge faces of zircon, its top side down, one can see the bottom of the ridge there are obvious double shadow, and no double image phenomenon diamond mens cufflinks. Glass of low refractive index, not the kind of diamond cufflinks flashing colored light; especially sinking into the water, no glass glory, immediately eluded capture. Men of gentle temperament are the best wearer of fine hand-polished cufflinks. The cubic zirconia was first developed by the Soviet people, hence the name. Soviet diamond is a man-made compounds, but in the dispersion, refractive index, etc. very close to natural diamond cufflinks, also has a "fire" an attractive shiny appearance. But its hardness is low (8.5), each designated with diamond cufflinks engraved distinction.
And thermal conductivity much lower than the diamond cuff links, can be "thermal conductivity meter" identification, accurate to distinguish. Cufflinks crystal clear though is a natural mineral crystals, diamond cufflinks like after processing, but the lack of light colored diamond cufflinks. Natural stone "Ten Red 9 crack", with no flaws and cracks in natural ruby cufflinks are extremely rare. The bold and burly man is more suited to the cufflinks of rough style.  The synthetic ruby cufflinks cuff same color, internal defects or crystalline inclusions small, clean, large block. As a precious gem cufflinks, the market of more than 3 carats are very rare natural ruby cufflinks, such as a large block across the ruby cufflinks, will attract attention, because natural than man-made ruby cufflinks ruby cufflinks worth a thousand times higher than the slightest negligence, will "take medicine."
    Natural ruby  have a strong "two color", so-called dichroism, from different directions to see if two kinds of red and orange-red hue, as only one color, it may be red spinel, garnet stone or red glass. Red spinel and ruby are very similar to the natural, the two most confusing, so be especially careful. Natural crystal cufflinks clear, often contain cloudy, star points, or flocculent gas-liquid inclusions, and often micro-cracks. Of course, in the low mood or the weather is cold, you may need to select a bright and colorful cufflinks to illuminate the emotions. In addition, the natural crystal cufflinks are polarized, visibility, twin phenomena, such as cuff links crystal ball, looking down from above, met with a double shadow phenomenon. Synthetic crystal cufflinks or glass products, pure homogeneous body, no cracks, often within a small bubble.
 Sphere from the top down view, see the following lines of double vision. Identify with the feeling can be felt more than the proportion of synthetic natural crystal cufflinks crystal cufflinks; natural crystal cufflinks have a sense of cold, and the glass with warm feeling. Olivine is a green cufflinks with yellow, middle and low gemstone cufflinks like olive, the market is the most common peridot colored glass cufflinks made of counterfeit goods. At the earliest, cufflinks are romantic jewelry of the western upper-class men. The main difference is that olivine cufflinks with a clear "double shadow", and the glass is not; olivine cufflinks often seen within the crystalline inclusions containing only air bubbles within the glass; the proportion of olivine cufflinks 3.5, hardness 7, compared with the proportion of glass (2.6) and hardness (6) must be large.
    Pearl cufflinks with natural pearls and cultured pearls cufflinks cufflinks divided, cultured pearl cuff links have water beads and freshwater pearls of the points. Production of natural pearl cufflinks less expensive; and cultured pearl cuff links can be mass production, so the price is much lower. The cufflinks now have developed into the label of the taste of the worldwide new and old gentlemen. The main difference between the two is that natural pearls and cultured pearls cufflinks there is no core. Natural pearl cufflinks often just some of the sand cores or parasites and other objects, not even nuclear. The cultured pearl cufflinks kernel is the artificial production of large beads, so the outside of the parcel layer thinner.
