Campus Sophisticate Collection 925 Pure Italian Silver NecklaceCampussophisticate 925 Italian Silver, also known as sterling silver, is the high end of a range of silver based products. Because pure silver is too malleable to use and scratches easily, sterling silver is composed of 92. 5 percent silver and 7. 5 metal. The metal, usually copper, nickel, or any other strong type, are strong minerals that make the end product stronger, shinier, and more durable.
