**For the best care of your jewelry, do not shower with your items. If your items do turn, it can be caused by a metal-to-skin oil reaction. As each person's body oils make different metals react differently, it is not our responsibility to return or exchange your item. We apologize in advance. However, we do offer cleaning and repair services for a fee. Please contact our customer service team for further details at tangpeng@szyukun.work for an assessment and we will send you a free estimate.
