Full diamond disc earrings, made of 925 sterling silver, with appraisal certificate, sterling silver platinum. 1 Why choose this sterling silver material? The advantage of sterling silver electroplating platinum is that it is highly wear-resistant. Even if the bottom of the ring is bumped, the inside will be white. However, it should be noted that sterling silver will oxidize. For example, this ring has oxidized. When maintaining it, wipe it clean with an alcohol cotton swab. 2 The diamond setting process is hand-made, and each diamond is very shiny. The diamond setting nail position is installed manually one by one. So it is very stable. If there is dirt inside the diamond nail position, just brush it clean with a toothbrush.
