Gold alloy compositions formed by environmentally friendly process

摘要

Rose-color and yellow-color gold alloys are formed from a gold-base alloy containing silver and copper. Mining these elements is usually highly detrimental to the environmental. Environmentally friendly alloys are obtained through the use of recycled elements and elements recovered from mines utilizing specific guidelines. Jewelry manufactured from these environmentally friendly alloys may be more receptive to a consumer, resulting in a competitive advantage.
