This ring is easy, peasy with the help of the nylon jaw ring pliers to round it out! Stamp a fun design on a circle blank and then shape it to match our rivetable ring and, voila! This ring is stunning AND comfortable. Keep in mind the rivetable rings come in sterling and plated, so if you want to match the metal color with the blank on top, use sterling or nickel silver with the sterling ring, or brass with the plated (so it will match the core of the rivet). We used copper with a plated ring so the brass looks like a design feature.
