Sterling silver isn't 100% pure silver, but an alloy containing 92.5% silver and typically 7.5% copper, a combination specifically chosen to give it incredible strength and durability while maintaining its beautiful luster. This precise blend makes it far more robust than pure silver, which is too soft for everyday items, allowing it to be crafted into everything from intricate jewelry to elegant tableware that lasts for generations. Without that touch of copper, your favorite silver pieces would quickly lose their shape!
