鉴别千足银手镯
要想精准知道是否千足银首饰，一是通过仪器扫描，这种检测是无损的，可以不损害首饰达到测定目的，不过这种仪器价格昂贵，一般只有专门的检测机构才有。
还有就是通过化学滴定（银可以用硝酸溶解后再滴定），这种方法检测银就反应掉了，没了。
另外鉴别真假银饰品的方法非常简单，只需要用磁铁与饰品相对，能相吸的就是仿银饰品
在对不同的仿银饰品进行磁铁吸引实验时，有的银饰品吸得很慢，而有的则瞬间就吸上了，这里面有两个原因，第一，吸引力与仿银首饰当中镍的含量高低有关系；第二，在合金钢镀镍材质当中，除了有镍的成分存在之外，还有铁的存在，所以加大了吸引力。
通过实验发现，磁铁的确可以辨别真假银饰，但是还是要提醒大家，最专业最科学的方法还是到专业的检测机构，用专业仪器来鉴定所买的银饰到底是不是真的。
千足银和它的保养方法，千足银是指采用先进的滤化工艺，提取出纯度和密度均高达99.9%的银质品。在国际市场，千足银的稀有度和价值略低于黄金，是普通的纯银3倍左右。其银白光泽自然天成，质地细腻光滑。千足银属中档贵金属，具有理想的硬度、亮度及光泽，及抗氧化性，而且能够牢固镶嵌各种宝石，非常适合高品质的饰品制作。千足银工艺原产于韩国，购买千足银，请认准925sv标志。
925sv在韩国、新加坡、香港、马来西亚等设有专卖店，目前，中国大陆仅采用韩国直送的方式购买。每件产品均独立附带唯一识别码，可直接在韩国官方同步认证商品真伪。
擦拭干净后再收起来
千足银饰品长时间不配戴，一定要用软布擦拭干净，免得汗渍留在饰品上造成腐蚀，然后放进密封袋或是包装盒内，好隔离空气避免千足银氧化变黄变黑。
不要碰到这些东西
泡温泉、在海边玩水千万不要配戴千足银饰品，也要避免接触到化学溶液，否则会起化学反应让您的千足银饰品变黑。
恢复光亮色泽
您可以使用擦银布擦拭千足银饰品的光滑面，雕花或是不规则表面，您可以使用软毛牙刷沾上少许牙膏轻轻刷洗，刷洗后让泡沫附着在千足银饰品上约一分钟，再用清水冲洗干净，用软布擦干。
千足银又称999银
925s又称925银
