925 silver refers to silver with 7.5% copper added during jewelry making. This alloy, containing 92.5% silver and 7.5% copper, is known internationally as standard silver and in the UK as Sterling silver.
Plain Silver
925 silver is plated with white rhodium (known in the industry as platinum) to minimize the yellowing and blackening of silver due to oxidation or sulfidation. 925 silver without the platinum plating is referred to in the industry as "plain silver," as plain silver oxidizes more easily in air.
Thai Silver
A specialty of Thailand, it also adheres to the 925 silver content standard. Handcrafted using the traditional silver blueing technique, this silver jewelry is extremely hard and resists deformation. Inlaid with natural gemstones, semi-precious stones, and animal teeth, horns, and claws, these pieces possess a strong sense of exotic culture. While generally priced higher than machine-made silver jewelry, they are still favored by consumers seeking individuality and uniqueness. Many small jewelry stores selling hairpins and clips also sell a type of imitation, aged synthetic metal from Zhejiang and other regions, also called Thai silver or Tibetan silver. This is actually just a lead-tin-plated synthetic metal, not genuine Tibetan or Thai silver.
In the industry, Thai silver refers to silver jewelry produced in Thailand with a silver content of at least 92.5%.
Miao Silver
The Miao people are a traditional group that favors silver jewelry. Silver jewelry is a favorite among the Miao, primarily used for women's adornment. Silver jewelry is diverse and can be found everywhere from head to toe, including headdresses, necklaces, shoulder ornaments, chest ornaments, waist ornaments, arm ornaments, and foot ornaments. These ornaments complement each other to create a perfect overall decorative effect. Among the Miao people, when a daughter is born, her parents begin preparing a dowry for her, and this dowry consists of silver jewelry.
According to historical records, Miao silver jewelry began to develop in southeastern Guizhou during the Ming Dynasty and has become a unique cultural feature of the Miao people. Visitors to Southeast Guizhou often buy a few pieces of Miao silver jewelry as gifts for friends and family. Miao silver jewelry is typically crafted by adding other alloys (such as copper) and 99% silver. The silver content is typically less than 15%. The silver content of Miao silver sold on the market has been steadily decreasing, with a Miao silver bracelet costing just a few yuan selling for as little as 50 yuan.
Tibetan silver
Generally containing no silver, it is a fancy name for white copper (a copper-nickel alloy). Traditionally, Tibetan silver is 30% silver and 70% copper. However, even this traditionally crafted "Tibetan silver" is no longer available on the market, with most products being made entirely of white copper.
Fake silver, often made from other metals with only a silver coating to deceive customers, can be easily misidentified as 999 or 925 silver because jewelry appraisal only examines the surface. Because jewelry appraisal only examines the surface, jewelry can easily be misidentified as 999 or 925 silver due to a thin coating of 999 or 925 silver. It is recommended that when inspecting silver jewelry, the most reasonable method is to cut a section of the silver jewelry from the middle and test the innermost part.
