There are many ways to identify the quality of a thing. For those who know how to do it, you can see the quality of the item by your own experience. If you don't understand it, how should you identify it? The author below will come to tell you the identification of red coral.
As red coral jewelry continues to become popular in the collection market, there are some phenomena in the market that pretend to be coral ornaments with other materials. Such as low-grade sponge coral, sea bamboo coral, poor dyed marble, pink glass, man-made materials and other synthetic corals. For buyers, first, choose to buy from reputable merchants. Second, because corals are rare, prices are not very cheap. If products that are too far from market prices need to be skeptical.
The common color of coral is red, pink, uniform color, translucent and natural. There are different wavy and fine longitudinal textures on the longitudinal section. It is difficult to see with the naked eye, but the texture of the sea bamboo coral is very obvious. Filled with dyed corals, the surface is smooth, rough and brittle, the color does not appear natural and uniform red, and is easy to fade. Some of these falsification methods have been passed down to the present, but it is not difficult to identify them: the “coral†made of materials contains bubbles inside, and the broken place is bright, there is no real coral fingerprint pattern; the “coral†made of glass is The shell-like fracture, while the real coral gap is smooth; the "coral" made with the surface is shiny, the cracks occur for a long time, the sound of the phase is boring; the "coral" dyed with bone horny is only wiped with acetone. It will be true and false.
The above is a brief introduction to the identification of a little red coral, not too comprehensive, if you are interested, you should learn more about this aspect.
