This ring boasts a lab-grown 4.00 ct diamond as its extraordinary centerpiece, cut in an elongated cushion emerald style that showcases its clarity and brilliance. Precision has been a factor in its construction as it is available in 18K Solid Gold and can be upgraded to 18K Solid Gold if preferred. This beautiful design comes in three gorgeous gold hues: rose gold, yellow gold, and white gold. The subtle 1.50 mm width and thickness of the band add a sophisticated touch to the ring while drawing attention to the brilliant center stone. Our laboratory-grown diamonds are of the highest quality in terms of VVS-VS clarity and E-F color, so the diamond shines out with a fire comparable to the best natural diamond.
