Is White Gold The Same As Platinum?

白金或鉑金都是 Platinum. 相反 White Gold 是 "K 白金" 或 "白K 金".

Platinum 學名為"鉑", 化學元素符號為 "Pt". 白金首飾一般都會打上 "Pt" 字樣, 例如 "Pt900", 表示這件首飾是用千分之九百的純白金製造. 常見的純白金有 "Pt950, Pt900, Pt850" 等分別.

White gold is an alloy of gold and some white metals such as silver and palladium. White gold can be 18kt, 14kt, 9kt or any karat. The natural color of White Gold is actually light grey. With Rhodium plating, White Gold will look more white than it should be. The color difference between Platinum and Rhodium plated White Gold is not noticeable. However, Rhodium does wear away eventually. Therefore, re-Rhodium plating is needed for White Gold by about every 12 to 18 months.

K 白金, 或稱 白K 金, 是黃金與其他金屬的合金. 因加入其他金屬的比例不同, 使其顏色像是純白金.但其價格比純白金便宜許多. K 代表黃金的純度, 如 14K 白金 和 18K 白金. 市場以 14K白金較為流行.

In general, a platinum ring will be approximately twice the price of an 18kt White Gold ring.
