Gold jewelry is jewelry made by adding other metals (such as silver and copper) to the gold material, also known as "opening gold" and "molding gold". Due to the different amount of other gold ornaments, different kinds of gold ornaments have been formed.
Among gold jewelry, pure gold jewelry is soft in texture, with teeth marks, easy to bend, golden in color, pure and soft, and heavy in touch. K-gold jewelry is hard and toothless, and its color is yellow with white, and with the decrease of gold number, the white gradually increases and the yellow gradually becomes lighter. The handle of gold jewelry is not as heavy as pure gold jewelry. In addition, both pure gold and K have seals, and the seals on gold ornaments are represented by the word "gold" and the English letter "one". Marked with the corresponding K number, in addition, there are seals on the jewelry, indicating the origin of different manufacturers.
Gold-plated jewelry is a layer of gold plated on the surface of other metal jewelry by electroplating. The color is similar to that of real gold jewelry, golden and bright, and it is not easy to identify when it is new. However, gold jewelry is light in touch, hard in texture, and easy to fade after being used for a long time. Some gold jewelry with bad electrical construction is either red, white or flowers.
Gold-coated jewelry refers to 24k or 22K gold foil wrapped on the surface of other gold carvings. For example, the gold box has high pressure, low pressure and poor flexibility. Bao Jinshou's appearance is similar to real gold jewelry, glittering, not easy to fade, and it is difficult to distinguish between true and false. However, careful observation of dents, included angles, backs, etc. of jewelry reveals that gold foil is uneven and peeling. For example, if there is a broken section on the jewelry, it can be seen that the broken business of the gold bureau material is yellow outside and white inside. In addition, the gold-plated jewelry feels lighter, the texture is harder than pure gold jewelry, the teeth bite the seal, it is not easy to bend, and it is easy to peel off when wearing gold foil for a long time.
Whether it is gold jewelry, gold-plated jewelry or copper jewelry, there is generally no seal similar to gold jewelry. Or stamps are different from gold jewelry, for example, some jewelry is engraved with the English letter "GK", which means "gilded". Or the signature is vague and crooked.
