Why 18K for diamond jewelry
It is harder than 21K, holds stones securely and suits fine designs. It can also be alloyed white (with palladium or nickel) or rose (with copper).
18 karat gold is 75% pure with the "750" hallmark, the standard for diamond jewelry, international brands and watches, available in yellow, white and rose.
