→ ktan:工廠是圖樣,店家是字 現在比較需要看到三角N,其它其實是其次05/11 17:25
推 elfinching:請問樓上 三角N是代表什麼意思呢 我的白金手鍊剛好有@@05/11 18:45
推 stupidboyu:有繳錢給檢驗局，有認證成份及格的05/11 18:48
因為以前大家回收黃金的提煉技術有好有壞 成色標示的標準也不一樣
造成很多糾紛 所以才推動這個三角N的標示logo
廠商如果想用這個logo 要繳交20萬元保證金
而且公會每月會進行分區抽查 如果被抓到或被檢舉偷工減料屬實
廠商就會被要求原價賠償給消費者而且沒收20萬保證金 同時取消logo使用資格
黃金製品的成分誤差值是不能超過0.03%的 不然就會視為偷工減料
然後有些術語大概要了解一下 就是足金跟純金的差別最容易起爭議
純金講的是金含量99.50%以上的24K
足金講的是金含量99.00%以上
22K金是金含量91.60%以上
18K金是金含量75.00%以上
只有24K才算純金 其它都應該視為金合金
