Lab-Grown Diamond Stud Earrings. A beautiful cornerstone for any fine jewelry collection, these timeless studs feature a pair of perfectly matched round brilliant-cut lab-grown diamonds. With a total diamond weight (TDW) of 0.50 carats. 14K white gold, the minimalist settings are designed to emphasize the pure beauty of the stones. Each diamond is cradled in a secure four-prong basket setting, intentionally engineered to elevate the stone and allow maximum light to pass through the facets for optimal fire and scintillation. The diamonds boast an excellent VS-SI clarity range and a brilliant, near-colorless F/G/H color.
