A great alternative to traditional diamonds, black diamonds are known for their elegant and exotic look. Trios of black diamond tube and rondelle beads are hand wrapped with recycled 18K gold wire into a sparkling and shimmering necklace. Each trio measures approximately 3/4" spaced apart and is available on a 16" or 18" with a hook and eye closure. The approximate total carat weight is 5.1. All diamonds are conflict free.
