Sterling Silver. Represents the purity of silver. It's 92.5% silver plus 7.5% alloy, which is the low purity of silverware, just like the purity of 999. Because silver is too soft and prone to oxidation. Silver is an active metal that easily reacts chemically with sulfur in the air, causing silverware to turn black. Therefore, when wearing it, try to minimize contact with air and avoid wearing it in places with high concentrations of chemical gases. After coming into contact with sulfur soap, wipe it dry. Due to the nature of silver itself, the silver floor is very soft and easy to scratch, and it is not suitable for the increasingly sophisticated craftsmanship requirements, as well as the increasingly rich and exaggerated styling requirements of modern popular jewelry. In addition, silver is prone to discoloration and loss of luster, so a 7.5% alloy was added to give silver ideal hardness, brightness, luster, and oxidation resistance And it can be inlaid with various types of jade and precious stones, making silver jewelry a new generation in the fashion industry with its bright color, unique style, exquisite craftsmanship, and mid-range fashion taste. Pure silver plated with platinum Silver is an unstable metal that turns yellow and black due to external factors, and there is currently no way in the world to prevent its change. Silver coated with platinum (palladium, rhodium) can effectively isolate silver from contact with the outside air. This platinum effect, depending on the degree of protection of the jewelry, can generally last for 4-12 months before turning into the silver effect itself. Pure silver (Thai silver) In order to conceal the color changing property of silver, another method is to directly sulfide it, making it impossible for it to turn yellow or black. The vulcanized silver presents a primitive and antique effect. This method originated in Thailand and is also known as "Thai silver". Usually, this Thai silver is used for men's jewelry. Silver (Plain Silver) The alloy of 92.5% silver and 7.5% copper is the standard for pure silver, usually plated with platinum (rhodium) to prevent yellowing or blackening due to oxidation or sulfurization. Silver without platinum plating is called "plain silver". Wearing precautions According to the principles described above, the following points should be noted when wearing silver jewelry: 1.
