How to identify platinum jewelry The platinum content in platinum jewelry is marked on the jewelry. We use a magnifying glass on the back of the jewelry, such as the buckle of the necklace, the inner ring of the ring, and we will observe the mark of platinum (pt 990, pt 950, pt 900). pt is the mark of platinum, and pt900 represents platinum jewelry with a pure platinum content of 90%. Usually full platinum is not used to make jewelry, but pt950, pt900 are used, and pt900 is used for inlaid diamonds or other gemstones. Because pt900 is mixed with other high-hardness metals, it increases the firmness of inlaid gemstones.
