PRECIOUS METAL TIME PIECES

Red Gold、Pink Gold、Rose Gold都是玫瑰金，究竟玫瑰金是甚麼？與其他材質又有何不同？玫瑰金跟黃金、白金一樣，都是透過不同材質與純金的混合所產生的貴金屬，不同比例所產生出來的貴金屬種類不同，色澤也不同。大致上的配方如下：

Be it 18k pink gold,yellow gold or white gold they are all gold the differences is the combination of metal within ....................pure gold is too soft to be made into a watch casing so only 18k gold is used

●18K玫瑰金(18k rose gold/pink gold)：75%純金(pure gold)＋25%銅(bronze)
●18K黃金(18k yellow gold)：75%純金(pure gold)＋15.5%銅(bronze)＋9.5%銀(silver)
●18K白金(18k white gold)：75%純金(pure gold)＋10%青銅(bronze) ＋15%銀(silver)
