The above lists the cultural and social impact of the pearl cuff links

At present, the domestic only Tonglushan, malachite can be used as a seal material loss. Cufflinks processing generally rough directly chamfering, coarse grinding (of angle), nest beads, polishing, drilling can be. Ring surface: Malachite is an opaque gem, so often cufflinks processed into convex type gem. Pattern changing, the band and banded malachite raw materials, in the cufflinks processing, in order to fully demonstrate the pattern of the changing characteristics, can be parallel, perpendicular, oblique laminae cut out the ring surface ornamentation. The integrity of the performance stripes gem cufflinks processing more lenient. According to statistics, in 2007, the sales of pearl cufflinks reached 50 billion yuan.  The design also make banded stripes with convex-type gem consistent with the long axis of the center of the concentric streaks on the convex gem at the top center position.
Perpendicular to fiber direction must be processed in the cufflinks for the radial structure of the raw materials (commonly known as fiber-type "malachite, stone visible flicker) Cutting, cufflinks processing of the cat's eye gemstone malachite. Fiber orientation and aspect direction perpendicular to the orientation is relatively easy. In recent years, the number of cufflinksin these industries continues to rise and industries have been expanding. Malachite hardness, wear cufflinks processing faster, modeling processes in silicon carbide grinding wheel on the 180 #, 180 # and 400 # emery cloth coarse grinding and fine grinding using agate powder or diatomaceous earth polishing powder in woolen. Malachite brittle, cufflinks processing to avoid the machine mechanical vibrations should also be kept cool continuous, interrupted cooling is likely to make the precious stones were fractured or cracks, especially when the polishing of the skin plate Note fever.
Malachite is a hydrated carbonate minerals react with acids, cufflinks processing to avoid contact with any acid. The chemical composition of amber is the petrochemical natural plant resin, resin acids and volatile oil, a variety of organic composition. Different plant species of different secretion resin, the formula can be broadly expressed as C10H16O, containing a certain amount of H2S. Slightly transparent; resin gloss; color yellow to brown, light red, sometimes green or light blue;The original stones of amber body amber with insect inclusions Amber cufflinks value of the processing of amber, the market a lot of amber ornaments is with the shaped cufflinks processing string system. Chunk or amber containing insects xenoliths can be used to make the carved pieces of the original block to save the smaller degree of cufflinks processing cabochon gemstones, beads necklace, faceted necklace with shaped diamond necklace ( figure). Zhejiang as the world’s largest origin of cufflinks in the past two decades extends the industry to all parts of the country. Precious stones arc generally Cutting width.
Hanging with the shaped amber variety of cufflinks cut amber jewelry. Amber hardness generally can be cut with a knife made of type. Cabochon amber gem with 240 # and 400 # of quartz sand paper for rough grinding and fine grinding. Amber gem polishing with chromium oxide, alumina, or diatomaceous earth polishing agent in the cloth disk, leather disk, or felt disc polishing can get a good polishing effect. Corals are marine life coral secretions. Aragonite composition of reef-building corals build coral animals in the warm shallow waters at depths of more than 100 m. The loose texture only for ornamental stones. The above lists the cultural and social impact of the pearl cuff links. Your corals by calcite is by living in the seabed in the deep waters of the coral animals build a smaller branching groups of corals. Is an important gem material.
