Pure gold is alloyed with metals such as silver, copper, nickel, and zinc to give it strength and durability. Karatage is expressed in 24ths and indicates how much of the metal mixture is in the gold. 24k is 100% gold.
The color of gold is determined by type of metal alloys included and the percentage of each metal alloy:
Natural gold and color-saturated alloys are what give yellow gold jewelry its rich shine. An expert mixture of copper, silver, and pure gold gives this precious metal its signature warmth.
Gold is mixed with metal alloys which are white in nature, and plated with rhodium. Rhodium can wear away over time, but replating to restore whiteness to white gold jewelry is a simple process.
BLACK RHODIUM/WHITE GOLD
Black rhodium is plated to white gold creating a black appearance. As with traditional white rhodium, black rhodium can wear away over time. Replating is simple and Molly's Jewelers can restore the black finish of rhodium jewelry.
The pink hue of rose gold jewelry is from a copper alloy mixture.
CARING FOR GOLD
To clean gold jewelry, use a mixture of warm water and detergent-free soap and clean jewelry with a soft bristled brush. To protect your jewelry, keep gold pieces in soft cloth bags or the original red Molly's box to protect them from dust, dirt, and daily exposure.
