In order to pursue a sense of fashion, the surface is generally polished into a matte surface in the form of matte. There is also a nail sanding process, and a granular matte surface appears on the surface. These are all existing platinum processes. Another advantage of this process is that it can make the ring not easy to scratch-the smooth process is very shiny, but it is easy to see tiny scratches after careful study. At present, the top and most perfect technology is platinum PT950 inner arc ring. I saw this kind of ring on Tmall's GsunG jewelry. Considering the beauty and comfort of wearing the inner curvature ring, the thinking concept of ergonomics is added in the manufacture. In fact, online shopping can save money, and you need to look at the pictures carefully to see if it is a boutique inner arc ring. I have been in the jewelry industry for more than ten years. At present, I find that Seiko inner arc ring is the most worth popularizing.
