Black Hills Gold uses the alloys to make different colors of gold.

The process of making Black Hills Gold jewelry begins with pure 24 Karat gold. It is alloyed with exact percentages of other metals to achieve a more durable karat quality of 10K, 12K or 14K. The traditional pink and green color gold used for leaves and other details is made when copper or silver is combined with the pure gold.

The original design was gold vines with green gold leaves and pink gold fruit or flowers.
