In the recent market, Nanhong has become the popular part of the South Red Agate collection, which is favored by consumers. And how do we identify Nanhong when we buy ? What are the methods?
1, color: South red agate., the common color is Gansu's persimmon yellow. (orange red), red, pink. There are also unusual purple, and the transparent or translucent color of these colors, including near transparent colorless It is roughly defined as the color range of South Red. The white texture is somewhat like the situation. There are also the textures like ribbons, which are half and half of the white and red. Here, the texture of Nanhong is very sharp, and all the lines are turning. There will be obvious angles (one of the important criteria for judging) to give people a clean and sensible feeling. (That is to say red and white!) In addition to the white lines, the red red will not change other than the transparent gradient. (sometimes mixed with some associated minerals, black or dark green)
2, texture: texture, South red is colloid. Even if the red beads are not opaque, you can see that the color is transparent from the inside out, consistent. In other words, even colorless Beads also have a feeling of embarrassment. Note here that this texture is temporarily unpreparable, unless the old material is new. So the fake South Red is basically made of pure red.
3, weathered lines: on the appearance of the beads, most of the old beads, especially the old chalcedony / manau beads will have a half-moon-shaped weathering pattern. This pattern is mainly because of long-term use, Dzi Beads and other high-value Laozhu has appeared the weathering pattern made by the new imitation of the beat, but it can be clearly seen that it is not consistent with the surface grout, and the size is uniform, dull, and the texture is dull (the crescent-shaped interior, the interior of the old weathered crescent is shiny) However, it is noted here that the dyed Nanhong produced in large quantities has not been weathered, and most of them are cracks on the surface of the agate made by direct high-temperature burning.
4, shape and patina: shape, common olive, round, pumpkin, slice, and multi-faceted beads (6 ribs, 8 ribs, 12 ribs, etc.) and a variety of carvings, and The main fakes in the market are olives and round beads. Also, note that the old beads are worn with other beads in the hundreds of years of use, so both ends of the punching area will have the same wear and tear as the cut surface; On the pulp, it is now found that the real beads are also dry, but it is by no means the obvious polished surface of the new imitation beads or new beads. The old beads are always oily and natural, (all old agate, chalcedony) .
5, punching and hole: South red agate punching is very characteristic, it may be double-sided drilling and then beading (the hole will not be small), after a long time of use. Therefore, because of the hole The wear is very smooth. If there is a clear spiral in the hole and there is a white powder, it can be judged that there is new work or dyed Nanhong.
In summary, it is Nan Hong's identification method. I believe it will be helpful to everyone. For more details, please pay attention to China Jewelry Merchants.com .
