About this collection
Engagement rings with a 3 to 3.99 carat lab-grown center diamond, our most popular size. A 3 carat round measures about 9.3mm across; ovals, radiants and elongated cushions face up even larger. Every center diamond is IGI certified and laser-inscribed, set by hand in our NYC Diamond District studio in 14K, 18K gold, or platinum.
