3 Carat Oval Engagement Rings

A 3 carat oval engagement ring has a long, bold outline that looks larger than a round diamond of the same weight. Every ring on this page is made in 18K or 14K solid gold, with a lab-grown or natural diamond.

Prices

• 18K gold, lab-grown diamond: $2,050 to $3,050
• 18K gold, natural diamond: $32,000 to $61,000

The carat weight in each ring's name is the total diamond weight. A solitaire carries all of it in the center stone. Rings with side stones split it across several diamonds, so they cost less at the same total weight.

How big a 3 carat oval looks

A 3 carat oval measures about 10.5 × 7.5mm. A 3 carat round measures about 9.3mm across. The longer outline makes the finger look slimmer.

Setting styles

This page has solitaire and side-stone rings. A solitaire puts all the attention on the center stone.
