The evaluation and purchase of jade cufflinks

Stained quartzite - Malaysia Jade: Some call it the "South Pacific Tsui, Malay jade cufflinks," "HAN". The main component is quartz, as grain structure. Not pure green nuanced and uneven distribution of hardness 6.5-7 density 2.63-2.65g/cm3, refractive index 1.55, observed under a color filter, dyed quartzite and soy-color jade cufflinks into a dark red, pink and crimson. natural emerald cufflinks color. devitrified glass emerald cufflinks: was translucent emerald green, the structure is similar to the natural jade cufflinks. Whether it is high polished or mercerized or honed, the unique silver gray of the cufflinks of titanium will have a better performance. The devitrified emerald cufflinks density 2.64g/cm3, the refractive index of 1.54, than natural emerald cufflinks small. Devitrified emerald cufflinks jewelry molds, poured out, but not the artificial cut marks, smooth ring surface. Under a magnifying glass can be observed within the teardrop-shaped bubble.
The difference between jade cuff links and similar natural gemstone cufflinks. Its similar to the natural gemstone cufflinks, jade, amazonite, grossular, prehnite, nephrite jade, chalcedony, Jade, Aventurine, Dushan and so on. According to the color, refractive index, hardness, density and other characteristics to identify the difference in the density and the average refractive index. The evaluation and purchase of jade cufflinks. It is one of the most suitable materials for cuff links in addition to precious metals like platinum and gold. Evaluation of the value of the emerald cufflinks, mainly from two aspects of color and texture. Color to emerald cufflinks color for the best green distribution and morphology of the green tape is the best. Texture to ground glass (meaning delicate, transparent to translucent jade cufflinks) for the last, "head" (referring to the transparency of the emerald cufflinks) foot the more the better, "head" poor second.
 The genuineness of the purchase Jade Cufflinks jewelry first identification of raw materials, if it is determined that is really expected, but also from the color, texture, stone flowers, Tsui lock crack, dirty black and cut type the careful selection in order to buy the Heart jade cufflinks jewelry. Emerald cufflinks are hard and strong toughness, but the emerald cufflinks products after processing thin wear should avoid touching knock, to prevent breakage. It is also often applied in modern mens cufflinks design in foreign countries.  Malachite cufflinks English name for the Malachite comes from the Greek Mallache, meaning "green". Malachite cufflinks green because the color is exactly like the spots on the peacock feathers and such a beautiful name. The ancient Chinese called malachite cufflinks for "Green", "malachite green" or "the Green Langgan". Malachite cufflinks is an ancient jade material.
Malachite cufflinks with copper carbonate minerals, chemical composition of Cu2 [CO3] (OH) 2, CuO71.9, CO219.9%, H2O8.15%. In the monoclinic crystal system. Crystal form often has a columnar or needle-like, extremely rare, and usually was hidden crystal bell milky, massive, hull shape, nodular and fibrous aggregates. We can say that titanium is the prevailed material in the cufflinks.  With concentric layered, fibers radially structure. Green, malachite green, dark green. Pattern often with a silky luster or shiny glass like transparent to opaque. Refractive index 1.66-1.91, 0.25 of the birefringence, pleochroism colorless - yellow and green - dark green. Hardness of 3.5-4.5, density 3.54-4.1g/cm3. Brittle, conchoidal to irregular-shaped fracture. Case of hydrochloric acid react, and easily dissolved.
Malachite cufflinks with similar jade difference. Malachite cufflinks with peacock green and typical bar for its identification characteristics, not easy to be confused with other precious stones, cufflinks, but with beryl, chrysocolla cufflinks. As to the models design of the cufflinks, the minimalist cleanly cut. The difference is: turquoise hardness 5-6, density, of as 2.6-2.9g/cm3 refractive index is small, 1.62. Chrysocolla the cufflinks hardness is small, 2-4, density 2-2.4g/cm3, refractive index 1.57.
