Five carats, shaped long and graceful. Each 5 carat oval lab-grown diamond ring comes complete, oval secured in its prongs and paid for in the listed price. Pick white, yellow or rose gold, or platinum, on the product page. The settings stay simple so the stone carries the ring: a plain solitaire, pavé shoulders, or a hidden halo beneath the oval.

Reading a five-carat oval
A 5-carat oval measures about 13 x 9 mm and reaches a long way down the finger. Ovals cut slimmer look longer; fuller ones look wider and brighter. Either way, the shape shows more face per carat than a round, so it reads as a very large stone.
Framing five carats
- Solitaire: a rounded shank with nothing between you and the oval.
- Pavé shoulders: rows of small lab-grown diamonds lead toward the center.
- Hidden halo: a band of small stones below the oval, seen from the side.
Metal under a big stone
Platinum holds its prongs firmly and wears well, a sensible base for five carats. White gold gives nearly the same look for less. Yellow and rose gold add a warm frame that makes the oval's white face stand out. Bands run about 1.8–2.5 mm.
Day-to-day with a five-carat ring
A stone of this height is exposed, so leave the ring in its box during workouts, yard work or moving furniture. Look at the tip prongs every couple of months and ask a jeweler to retighten any that feel loose. A weekly wash in warm water with gentle soap and a soft-bristled brush keeps the oval clear.
5 Carat Oval Lab-Grown Diamond Rings: Common Questions
How much does a 5 carat oval diamond ring cost?
From about $3,350 in this collection, with most rings between about $3,500 and $3,650. That price covers the ring and its 5-carat oval lab-grown center in the lowest-priced metal; platinum and pavé raise it. A mined oval of equal weight would cost many times as much, though lab-grown stones keep little resale value.
