Pink gold.

It is generally called pink gold that is made up of 750‰ of gold in total, and among the rest, copper with 80% and silver with 20% in the case of K18. (Sometimes palladium is added, and the mixing ratio may be different.) The color tone is close to silver but it is affected by copper and comes out slightly pinkish color.
It is the hardest, elegant and exclusive atmosphere among K18.


K18の場合、金が750‰、残りのうち、銅が80%、その残りが銀の合金を一般的にピンクゴールドと言う。(パラジウムを加えることがある。また、混合率が異なる場合もある。)色合いは銀に近く、わずかに銅の赤みが出て、ピンクがかった色となる。
K18のなかで、一番硬く、上品で高級な雰囲気を醸す。
