Jewelry inlay is a high-tech skill. Jewel setting is a kind of processing technology in which precious stones (including natural precious stones, semi-precious stones and artificial gem) are fixed on supports (pendants, earrings, chains and other jewelry used for setting precious stones) by various appropriate methods. Jewelry inlay processing began in the west, and its technical difficulty is more delicate and complicated than traditional oriental jade carving. It pays attention to design texture and exquisite craftsmanship. In jewelry modeling, we can highlight the material characteristics of jewelry, and the combination and contrast of various materials make the whole jewelry more fashionable and decorative.
