Kin
The two sides of this ring are represented as opposites - one being an organic and smooth shape and the other being a sharp, geometric form. These two ends might seem like an unlikely pair, however, this ring brings them together in a way in which it is impossible to tell where the contrasting forms turn from one into the other.
