羊城晚报讯 记者帅鹏坤、通讯员赵建勇报道:近日,广州黎小姐向省消委会投诉称购买的邮票金上“生锈”了,怀疑买到假货。专家表示,生锈是正常现象。
2010年,广州的黎小姐购买了广州保税区创艺贸易有限公司(广天藏品)的一套邮票金,每件5克一共12件。今年2月,她发现邮票金出现红斑等生锈现象。经销商称金子生锈是正常现象,且纯度越高越容易生锈。
在省消委会介入调查后,广天藏品回复称广东省珠宝玉石及贵金属检测中心已于2013年5月3日对 黄金 “生锈”现象作出了说明,黄金出现红斑或是白斑,为黄金饰品、工艺品的常见现象,属于制作过程中,生产车间或是模具上有灰尘,压印之后就容易在成品上出现红斑。且黄金表面处理越来越复杂,其表面不平更容易藏污纳垢,黄金存放的环境比较潮湿等客观因素,都会使黄金出现“生锈”现象。因此,他们自称无过错,并不需要对消费者作出赔偿,可为客户提供免费的专业清洗服务,使货品恢复原貌。
上述说法也得到了省消委专家的认同。专家表示,低纯度金饰品表面的“生斑、生锈”是比较容易理解的老问题,但近两年,高纯度千足金饰品表面“生斑、生锈”引发新的关注,而目前无此方面的相关标准。但经科研发现,这些“锈斑”,其实是纳米级的生产污染物,后期与空气接触后在产品表面形成的薄膜,“锈斑”的有无与千足金的纯度无关,建议保存时注意清洁保养。
