2 CT Elongated Cushion Lab Grown Diamond Ring vs 2 Carat Round Diamond Engagement Ring

Both are 2-carat lab-grown diamond rings with IGI certification and a four-prong setting. The Elongated Cushion (A) is the pick if you want a distinctive shape, a colorless DEF stone with VVS-VS clarity named up front, and a choice of 14K white, yellow or rose gold. The Round (B) is the pick if you want the classic brilliant cut, a lower basket setting that sits closer to the finger, and a broader choice of metal and stone size. Owners of B praise the sparkle and craftsmanship, and it holds a 4.9 rating from 38 buyers. A's cushion cut reads larger edge to edge but can look smaller than a round of the same weight.

• Choose the Elongated Cushion if you want a less common shape, a colorless VVS-VS stone spelled out on the certificate, and 14K solid gold in your choice of color.
• Choose the Round if you want the classic brilliant cut, a low basket setting for daily wear, and options like platinum, 18K gold, engraving and stone sizes from 0.50 to 3.00 CT.
