3 ctw Oval Lab Grown Diamond Solitaire Ring vs Pompeii3 3.40Ct Lab Grown Diamond Engagement Ring

Pick the oval solitaire (A) if you want one clean, large center stone in 18K gold and a certified F/VS2 diamond. Pick the round pave ring (B) if you want more total sparkle across the band and a slightly larger overall look in 14K gold. A is the purer solitaire with finer metal and tighter color and clarity grading; B spreads its carat weight over 27 stones, so the center is smaller than the 3.40 total suggests. Owners of both styles praise the brilliance, but expect B's SI1 accent stones to show more variation than A's single VS2 stone.

• Choose the oval solitaire if you want one big certified center stone, 18K gold, and a classic single-stone look.
• Choose the round pave ring if you want extra sparkle down the band and a round brilliant cut with ideal proportions.
