银手镯变黑属于正常现象，跟银的质量关系不大，银在空气中容易氧化，如果变黑的话，可以用牙膏牙刷，刷洗，很快就会变得白亮。
纯银饰会发黑是因为氧化，而氧化的原因会有很多，比如空气，汗水，酸性侵蚀，洗澡时佩戴等，并不是有毒素，只是体质偏酸的可能，属正常现象。意建议经常清洁擦拭，或者到专业银饰店清洗抛光，不佩戴时需隔绝空气保存。
保养方法：
一、用牙刷沾一点牙膏反复清洗，这种方法适合表面平整光洁的银饰，如果是工艺复杂的银饰品，如果镂空、雕花的用这种方法效果可能不太好。
二、苏打溶液中加入一些铝片，然后把发黑的银饰放在里面一起加热，能去除黑色，镶嵌宝石的银饰除外。
三、用热的肥皂水清洗后再用硫代硫酸钠溶液浸润银首饰，然后再用牙刷或纤维布擦试。
四、对于发黑严重的银饰品，可用盐酸清洗后用清水漂干净，同样镶嵌宝石的银饰除外，否则会造成宝石损坏。
五、当银饰不佩戴时，取下来，如果容易出汗，那么必须将银饰晾干后放回袋子中，密封好放回盒子。
银手镯上产生黑斑的原因有以下3种：
1、氧化，银手镯遇上氧气后会发生氧化反应，产生黑斑。
2、纯度，银手镯上的黑斑会受到纯度影响有所差异，纯度越高越明显。
3、汗液，人体汗液油脂会与银手镯之间产生化学反应，出现黑斑。
银手镯上出现黑色斑点可以用以下方式擦掉：
1.使用牙膏。一般银手镯变黑我们可以使用牙膏来去除，将牙膏少量涂抹于黑色斑点处，然后使用牙刷对其反复使劲刷洗，直到斑点处呈现银色即可。
2.使用可乐。将有黑色斑点的银手镯寖泡的少许可乐中，需要可乐完全寖泡住手镯，等待5-10分钟，取出银手镯再用干净的毛巾将其擦洗干净即可。
3.使用擦银布。使用专门的擦银色布，缠绕银手镯反复搓擦，银手镯上的黑色斑点就会慢慢消失了。
4.使用食用醋。醋属于酸性的，可以起到腐蚀的作用，将布用醋水寖湿，然后擦洗银手镯黑色斑点处，也可以有效去掉银手镯的斑点。
5.茶水，茶水属于弱软性，对去除银手镯上的斑点也会有很好的作用，可以将有黑色斑点的银手镯寖泡的茶水中，经过一段时间后取出，使用棉布擦干净就可以了。
以上回复说是镀银的人是没有生活常识的 作为一个从事银饰销售行业13年的人来告诉你 银饰在佩戴以后出现小黑点都属于正常现象 银饰是活性金属 在遇到氧气以后会发生氧化反映 而且也会根据个人的体质情况发生颜色的变化 有的人佩戴银饰很亮很白 但是有的人佩戴银饰颜色会偏暗 银饰 也会根据自己最近身体的状况而发生颜色的变化 所以银饰又有身体晴雨表之说 在银饰发生氧化反映也就是变黄变黑之后 我们可以用牙膏来清洗 对于氧化较严重的银饰我们可以用专门的洗银水来清洗 一般我们在店面里购买的银饰都不会有假 首先银饰的成本本来就不是很大没有必要造价 市面上常见的假银饰主要是白铜 白铜泛金属颜色 而银色比较偏白 所以是很好辨别的 不能因为它变黑了就能判别出来他是假的
你买的是度银的吧
