Pompeii3 3Ct Cushion Lab Diamond Solitaire Ring vs Pompeii3 2Ct Lab Grown Solitaire Engagement Ring

Both are 14k white gold solitaire lab-grown diamond rings from Pompeii3, size 8, made in the USA. The 3Ct Cushion is the bigger statement stone with a softer, more unusual shape; the 2Ct Round Cathedral is the classic look with a brighter, better-graded cut and a resizable band. Reviewers of Pompeii3 solitaires praise the sparkle and craftsmanship but note lab diamonds and thin prong settings need care. Pick the cushion for size and a distinctive shape, the round for timeless brilliance and easier resizing.

  • Choose the Pompeii3 3Ct Cushion if you want the larger stone and a softer, less common cushion shape.
  • Choose the Pompeii3 2Ct Round Cathedral if you want the classic round brilliant look with a resizable band and a well-graded cut.

Questions and answers

Which looks bigger, the 3 ct cushion or the 2 ct round?
The 3 ct cushion faces up larger, but a cushion spreads its weight differently than a round, so the visual gap is smaller than the carat gap suggests. The round looks brighter for its size.
Which is better for everyday wear?
The 2 ct round cathedral sits lower and is resizable, which suits daily wear. The 3 ct cushion is taller and its size makes it more prone to knocks.
Does cut quality matter more than carat size?
Yes for sparkle. The round's excellent cut grade will outperform a larger stone with no stated cut grade. The cushion wins on size, the round on brilliance.
Is the 3 ct cushion worth stepping up to?
Step up if size and a distinctive shape matter most. If you want the brightest, most classic stone and a band that can be resized, the 2 ct round is the safer choice.
Are both rings lab-grown diamonds?
Yes. Both use lab-grown diamonds in 14k white gold, made by Pompeii3 in the USA.
Can the 3 ct cushion be resized?
The listing does not confirm resizing for the cushion. The 2 ct round is listed as resizable, so confirm sizing with the seller before ordering the cushion.
