Round Cut Lab Grown Diamond Cluster Ring, 3.87ct Total, Solid Gold

This 3.5 carat round lab-grown diamond engagement ring is built around a 10.00 mm, 3.50 ct center stone with its IGI certificate, finished with two marquise and two small round diamonds for 3.87 CT TW on a 1.97 mm band. The slim band and small side accents keep the focus on the large round center, which is the real show here. It is a ring for a once-in-a-lifetime proposal or a major anniversary, and lab-grown makes a center this size far more attainable.
