What Are the Properties of Silver?

Pure silver is metallic silver with a content close to 100%. Silver is chemically inactive, but because silver has a special affinity for sulfur, it can slowly form silver sulfide in the air, making it black, making silver impure. Moreover, in nature, silver is easily mixed with metals such as platinum, so the "pure silver" in life generally refers to silver with a content of 99.99% or 925 silver with a content of 92.5%.

Due to the characteristics of silver itself, 100% silver is very soft and easy to scratch, and it is not suitable for more and more fine craftsmanship requirements, and the increasingly rich and exaggerated modeling requirements of modern popular jewelry. Coupled with the fact that 100% silver is easy to discolor and lose its luster, therefore, in 1851, Tiffany introduced the first set of 92.5% silver

Primary color,

925 silver: refers to silver containing 92.5% silver, which is recognized as a pure silver standard in international standards. 100% silver is softer, it cannot be formed during production, it is inconvenient to make silver jewelry, and it is easier to "oxidize", commonly known as "discoloration"

Plain silver: The industry refers to 925 silver that is not plated with platinum (that is, white rhodium, or platinum in the industry) as "plain silver". Prime silver is relatively easy to oxidize in the air. A large percentage of the 925 silver products on the market are plain silver in order to reduce the cost. After gold plating, it can delay the yellowing and blackening of silver in the case of oxidation or sulfuration.

Thai silver: Thai specialty, the standard is also 925 silver content. The appearance lacks brightness, and pursues an "ancient" and "old" "ancient silver" effect. Compared with 925 silver plated with platinum, because the public base is not broad enough, compared to 925 silver, the price is lower.

Tibetan silver: Generally, it does not contain silver. It is the name of white copper (copper-nickel alloy). Traditionally, Tibetan silver is 30% silver plus 70% copper. It is no longer visible, and most of them are replaced by completely white copper. ^[2]
