LAB GROWN OVAL CUT DIAMONDS

An oval is a round brilliant pulled long. It keeps the same faceting, so it keeps the sparkle, but the weight spreads down a longer outline and it reads bigger than a round of the same carat. We make all 32 designs, rings, bridal sets, pendants and studs, every one of them lab grown, in 14K or 18K white, yellow, or rose gold, or platinum, with prices ranging as low as $850.99

THE DETAILS

Buying a Lab Grown Oval Cut

An oval buys apparent size. Here is what that's worth, and the one thing to look for before you commit.

Yes, and noticeably, at the same carat weight. A circle packs the weight under the middle of the stone; an oval lays it out along the length, so more diamond faces up. That's most of the reason people choose it.

A dark band across the waist of the stone, caused by the way light bends in an elongated shape. Every oval has one to some degree. A well cut oval keeps it faint, and we don't buy the stones where it takes over the face.

Between 1.35 and 1.45 times as long as it is wide is the classic oval, and it's what most people picture. Under 1.30 it starts to look like a round that didn't quite make it. Over 1.50 it reads narrow, which is exactly what some people want on a long finger.

It is diamond, graded on the same color and clarity scales as a mined stone and identical to one under a loupe. What changes is where it grew and what you pay: it's well below a mined oval of the same specification. Lab grown diamonds of 1.00ct and above come with an IGI certificate.

Better, arguably. A pendant hangs with the long axis pointing down, which is the orientation an oval wants anyway, and you're not looking at a pendant from six inches away, so the bow tie has nowhere to announce itself. There are oval pendants and oval studs on this shelf, not only rings.

About Our Lab Grown Oval Cut Jewelry

An oval trades depth for spread. The weight sits along the length of the stone rather than under the middle of it, so more of the diamond faces the room and less of it hides in the setting. On a hand it lengthens the finger, which is a real effect and not a sales line.

All 32 designs here are made to order in our own US factory, in 14K or 18K white, yellow or rose gold, or in platinum, around the center weight you choose.

Rings lead the shelf, and they aren't all of it: bridal sets, solitaire pendants and stud earrings sit alongside them. The stones run every one of them lab grown, a few of the bridal sets are set with fancy blue, pink and yellow diamonds, and prices range as low as $850.99.

Every piece carries a Lifetime Limited Labor Warranty on the setting work, ships free inside the US, and comes back within 30 days of the ship date if it isn't right. Every order includes a PrimeStyle Jewelry Report with the metal, the diamond specifications and the value for insurance.
