Round Cut Lab Grown Diamond Solitaire Ring, 1.78ct Total, Solid Gold

This round lab-grown diamond engagement ring with trillion side stones pairs a 1.33 ct, 7.20 mm IGI-certified center with two triangular trillion diamonds and 14 small round accents on a 2.00 mm band (1.78 CT TW). The trillions widen the look of the center and add a sharp, geometric sparkle that reads beautifully across the room. It is a strong choice for a proposal if you love the presence of a three-stone ring but still want the round diamond to be the clear star.
