Lab-Grown Diamonds · Made to Order · IGI Certified
A one-carat lab-grown diamond is the classic engagement-ring starting point — large enough to read clearly across a room, restrained enough to keep the eye on cut and proportion. Because every Sula ring is made to order, you choose your exact weight (we cut from 0.5 to 3 ct); at one carat, our centers are D–F color, VVS clarity, IGI certified, set in solid 18K gold or platinum. Lab-grown pricing also means a one-carat budget buys a higher color and clarity grade than the same spend would mined. Browse every shape and setting below, each available at one carat.
