The Dual Byzantine weave, made using strong and beautiful bronze. Along with stainless steel, bronze is one of the hardest of the heavy metals I work with. The price is therefore slightly higher than the same thing in aluminum, brass, or copper. But the bracelet is more durable as well. Bronze is a copper-tin alloy, and because of this, it will oxidize over time like a penny and become darker. Some people enjoy this feature of the metal, but it can also be cleaned to bring bring back its shine. This bracelet is held closed with a copper-colored buckle clasp.
