Gold

Gold won't tarnish, rust, or corrode. Though gold is very strong, especially K-gold, it is also the most malleable of all metals.
黄金纯度

Purity

Pure gold is too soft to withstand the stresses of every-day wear, so it is alloyed with a mixture of metals like silver, copper, nickel, and zinc to give it strength and durability. Karatage, noted by a number followed by "k" indicates purity, or how much of the metal in a piece of jewelry is gold. Karatage is expressed in 24ths, making 24K-gold 100% gold.

Gold Care

Keep your gold jewelry away from harsh chemicals such as chlorine and cleaning fluids. This will reduce daily abrasions and prolong gold's luster. To clean gold jewelry, use a solution of warm water and detergent-free soap nd wash gold gently with a soft-bristled brush (a dull tooth brush works well). Store gold pieces separately in soft cloth bags or original boxes to protect them from the exposure to harsh daily elements.
