Copper is a very beautiful and versatile metal. In its natural state, copper has a warm, earthy, orange-ish hue. Genuine copper clasps pair extremely well with blues and look dramatic yet earthy with green. Antique copper is a plate, usually applied to a base metal such as pewter, that has an old world look and feel. Use antique copper clasps in beaded designs where you are using gemstones, particularly turquoise.
