4Ct Oval Solitaire Lab Grown Diamond Ring vs Pompeii3 2Ct Lab Grown Solitaire Engagement Ring

Buy the 4 ct oval if the size of the stone is the point and you want a warm-toned solitaire in yellow or rose gold. Buy the Pompeii3 2 ct round if you want a brighter, better-cut stone in white gold with a cathedral setting that sits lower and feels sturdier. The 4 ct wins on presence; the Pompeii3 wins on cut grade, resizability and US-made construction. Owners of both report happy engagements, but the 4 ct's G-H/VS-SI range is wider, so ask for the certificate before you commit.

• Choose the 4 ct oval solitaire if you want maximum finger coverage and a classic single-stone look in 14k yellow, white or rose gold.
• Choose the Pompeii3 2 ct round if you prefer a precisely cut round brilliant in white gold, a cathedral setting and a ring that can be resized.
