🗣 SL提问: 怎么判断黄金手镯是不是真的

✍️ Ai批改: 要确定一个金饰是否为真，可以采取以下几种方法：

1、看证书：正规的珠宝店会提供鉴定书或购买发票。如果这些文件齐全且信息一致，则说明该饰品是经过专业机构认证过的。

2、观察颜色和光泽度: 真正纯金的颜色应该是淡黄色或者金色，并带有金属质感；而假货则可能呈现暗黄甚至发黑等异常现象。
3、检查重量与体积比值 : 一般来说,同样大小的情况下 , 实心黄金制品要比空心轻很多。可以通过称重来对比一下实际重量与其标示出来的理论重量是否有较大差异即可得出结论了；
4、用火烧：将首饰放在火上加热后冷却再触摸表面温度变化情况若发现其变凉较快那么就有可能不是真正的黄金因为高温下合金成分会发生氧化反应导致硬度降低从而使得手感变得柔软易碎等等特征出现相反的话则是正常表现形态不变证明它是由贵金属制成而非普通材料所构成;
5、使用酸液测试法（仅适用于专业人士）：
