"Bioband" con Rodolite Cabochon tanzanite The gem appears slightly included"Biobands" are rings that mimic the shapes found almost everywhere in nature when evolution expressed the need to create resistant but at the same time light structures. From sea sponges to inside bones it is everywhere; it is literally the structure that supports nature. This is a ring (also chosen by many as a wedding ring) that is unique, irregular, comfortable and light.
