What Is Sterling Silver?
Pure silver is relatively soft and malleable, and easily damaged—not well suited for jewelry. To defend against deformation or destruction, silver is combined with other metals to make it more durable. Sterling silver is the most common alloy mix found in jewelry. It must be at least 92.5% 순수한은, but the other 7.5% can be any metal. Typically, this alloy is copper. Centuries of experimentation have shown copper to be silver’s best companion, without affecting its beautiful color. The small amount of copper added to sterling has very little effect on the metal’s value. Instead, the price of sterling silver is affected by the labor involved in making the item, the skill of the craftsperson, and the intricacy of the design. Also, jewelry made with sterling silver is often plated with rhodium to give it a bright white finish that is a bit more resistant to scratching.

History And Hallmarks
Making jewelry and currency out of sterling silver has been a practice for a very long time—since around the 12th century to be more accurate. Silver coins from this era were referred to as “Easterlings,” especially in the cattle markets. Eventually, the name was shortened to “Sterling” which is now used to denote the highest grade of silver. Fondly referred to as “the metal of the moon,” because of its milky white and greyish color, sterling silver is commonly stamped with what’s known as a hallmark. The hallmark indicates the amount of pure silver content, and sometimes denotes the date of completion and country of origin. And under federal law, it must be accompanied by a maker’s mark or registered trademark. Acceptable quality marks for sterling silver include:
