925 sterling silver plated with platinum. Compared with gold, silver is a relatively unstable metal that will turn yellow and black due to external factors. There is no way to stop this change internationally. Plating platinum (palladium and rhodium) on 925 silver can effectively isolate 925 silver from the outside air. This platinum effect can last for 4- 12 months according to the different protection procedures of jewelry.

925 pure silver contains 925%(92.5%) silver, which is different from traditional pure silver. In order to strengthen the hardness of silver ornaments, about 7.5% copper is added, so the silver color of 925 silver will appear gray instead of the silver color of traditional silver. Silver is an unstable metal. The oil on the surface of a healthy human body can keep its natural color. If it is worn for a long time and exposed to the air, it will turn yellow. When it comes to chemicals (such as hair gel and soap) that deposit toxins in the body or comes into contact with sulfur, it will suddenly turn black. Therefore, whether wearing silver ornaments can effectively maintain its true colors is also a manifestation of good health.

The higher the purity, the whiter the silver, and the surface of jewelry looks even, shiny and polished. If it contains lead, the jewelry will appear bluish gray; If it contains copper, the surface of jewelry will be rough and the color will not be moist.
