Specs: Gemstone: Opal Setting:Prong Setting Main Material: Copper Alloy Style: Romantic Copper Durability Part of the allure of copper is its extreme durability. Pure copper is not very strong but it is tough and pliable. When it is combined with other metals such as zinc and tin, the resulting alloy is very strong. There are many alloys made of copper, including bronze, brass and sterling silver. Because of its pliability and durability, many jeweler’s prefer crafting their designs out of copper. With reasonable care, copper can last several generations. REASONABLE CARE includes washing your ring with soap and water. The ring May oxidize with your skin which is why care is required.
