About this collection

Engagement rings with a 4 to 4.99 carat lab-grown center diamond. A 4 carat round measures about 10.2mm across, a true statement stone at a fraction of the cost of mined. Every center diamond is IGI certified and laser-inscribed, set by hand in our NYC Diamond District studio in 14K, 18K gold, or platinum.
