Type of silver: [full silver] Silver with a silver content of not less than 990. Because it is too soft, it is not easy to be cast into a favorite jewelry shape, and it is easy to wear and oxidize and blacken. Very soft, so it is not suitable for jewelry making. [sterling silver] [925,950, 99 silver] â— 925 Silver: refers to silver containing 92.5% silver, which is recognized as a pure silver standard in international standards. 925 means that the silver content is not 100% because the hardness of the 7.5% alloy added in pure silver is enhanced. 925 silver plated white enamel (called platinum in the industry), can maximize the characteristics of yellowing and blackening under oxidation or vulcanization, and enhance brightness after polishing. In the industry, 925 silver without white gold plating is called “silver silverâ€, which remains silvery white. Because it is not specially processed, the surface of plain silver is easily oxidized in the air, but it is easy to clean. . . . â— Of course there are 950 silver. Between 925 and 990. â— 99 silver: 99 silver is a high-purity silver that has not been mixed with alloy. Many styles are not suitable. Unless it is brushed or small or large and thick, hand-made silver is more than 99 silver. Due to the complicated workmanship of the Miao silver ornaments, other places cannot be copied. The sterling silver jewelry on the market is generally finished with molds or 925 silver products. [Tibetan silver] In fact, it is an alloy. In Tibetans, Tibetan silver is actually white copper. Tibetan silver is the nickname of white copper (copper-nickel alloy). Traditionally, Tibetan silver is 30% silver plus 70% copper. Most of the silver jewelry on the market today is 30% silver plus 70% alloy. [Miao Yin] Also known as Yunnan silver, non-pure silver, is a kind of silver metal unique to the Miao. Its content is silver. White copper, etc., contains about 40% of silver, so the general price is relatively low. [Thai Silver] In fact, it is a special process. There are 925, there are 99. Also known as "Wuyin", it is a mixture of silver and sulfur on silver jewelry, and a cover layer is formed in a vitreous state. The black-silver cover layer is loose and black, which is in sharp contrast with the smooth silver of silver, resulting in special visual effects. Due to the special anti-old treatment, the black and silver jewelry not only does not change color for a long time, but also the surface hardness is greatly enhanced. The unique texture and color make this jewelry rough and simple. [raw silver] Since there is no further purification of raw silver, it still contains lead, copper and other metals, which are not high in purity and therefore very hard. Raw silver said that there is no processing. Actually, the silver material used is not further processed, and there are impurities. The "Heavenly Creations" contains the following steps: Because of the certain impurities in raw silver, I personally think that it should not be worn as jewelry, so as to avoid allergic reactions. [Old Silver] Old silver will only be a good sterling silver with a classic luster after years of testing. The former name is "foot silver" and "grain silver", and the purity is at least 90 or more. The so-called past technology is poor, the old silver silver is only 40% or 60% low, are some misunderstanding or dishonest business fabrication concept misleading purchase.
