One, two or three? The center engagement ring says I'M REALLY ENGAGED with a 1 1/2 carat oval diamond. Turning off the gem function on our CAD design let the metal on the center ring show off this center. The matching rose gold bead set wedding bands really accentuate the engagement ring, saying I'M MARRIED!!! Prices for the center ring start at $ 2100.00 without the center.
