Distinguishing features of diamonds and their imitation crystals
Due to the scarcity and high cost of diamonds, many diamond imitation crystals appear on the market. These imitations are mainly five-color gemstones, such as colorless glass, five-color zircon, colorless crystal, colorless sapphire, colorless topaz, colorless spinel, synthetic rutile, artificial barium titanate, yttrium aluminum garnet, enamel Gallium garnet, synthetic cubic zirconia, synthetic carbon silica, and the like. At present, synthetic cubic zirconia and synthetic carbon silica are the most ideal imitations of diamonds. The distinguishing characteristics of diamonds and their imitation crystals are as follows: 1. Glossy diamonds have the characteristic diamond luster, which is one of the main features distinguishing them from other imitations. 2. Fire-colored characteristic diamonds exhibit a special "fire color" due to their high refractive index and high dispersion value. The fire of the diamonds is soft and has a sense of jumping, while the diamond imitations are dull and monotonous. 3. The perspective effect puts the diamond table down on a piece of paper with lines. The perfect diamond can't see the lines on the paper, otherwise it is a copy. 4. The lipophilic natural diamond has strong oil affinity, and the oily pen can leave clear and continuous lines when it is crossed on the surface of the diamond. On the contrary, when the surface of the diamond imitation is crossed, the ink will gather into small oil droplets. A continuous line appears. 5. Hydrophobicity points small droplets on the surface of the diamond. Water droplets can remain on the surface of the diamond for a long time. If it is an imitation, the droplets will spread quickly. 6. Good thermal conductivity Because the diamond has a high thermal conductivity, it can be found that the fog disappears quickly against the diamond, while the imitation can see obvious fog on the surface, and it takes a while to disperse. 7. The flat edge is straight and sharp. Since the diamond is the hardest material in the world, the ridgeline between the polished diamond facets is straight and sharp, the imitation is small in hardness, and the ridgeline is smooth and wearable. Rubber Bushings, usually called Rubber Sleeve Bearing, Rubber Sway Bar Bearing, Rubber Damper,Rubber Flange Bearing, Rubber Plain Bearing,etc, is a fixed or removable cylindrical lining used to constrain, guide, or reduce friction toprotect an inside surface, which is known as an insulating lining for a hole through which a conductor passes and an adapter threaded to permit joining of pipes with different diameters.often with screws.
