An enduring element found naturally in a distinct yellow color. Gold has an extraordinary heritage with unique qualities. Gold is resistant to rust, tarnish, and corrosion. Although gold is very strong, it's also the most malleable of all precious metals. Pure gold is too soft for everyday wear, so it is alloyed with a mixture of metals like silver, copper, nickel, and zinc to give it strength and durability.
Relatively soft, very malleable. Pure silver, also called fine silver, is commonly combined with other metals to produce a more durable product. The most popular of these alloys is sterling silver, which consists of 92.5 percent silver and 7.5 percent copper. Although any metal can make up the 7.5 percent non-silver portion of sterling, centuries of experimentation have shown copper to be its best companion, improving the metal's hardness and durability without affecting its beautiful color.
