Bronze is an alloy made of copper and tin, has a beautiful warm golden tone, and is an affordable alternative to 10 or 14k gold.
Bronze does have one DRAWBACK, which is that the copper content can cause an oxidation reaction with your skin oils, creating a greenish layer of copper carbonate.
This layer is easily washed off, and you can minimize the oxidation by taking your jewelry off at night, and washing it regularly with soap and water.
