Oval Cut Lab Grown Diamond Swirl Bypass Engagement Ring with Pave in Silver, 10K, 14K and 18K Gold

An oval laboratory grown diamond set across the finger, with the band dividing beneath it into two arms that cross: one left plain and polished, the other set with small round diamonds. The two sweep past each other in a swirl rather than meeting.

One plain arm, one set

The two halves of the band are deliberately different. One is polished metal, wide enough to read as a clean curve. The other carries a line of pave that follows the same sweep. Because they are not matched, the ring has a direction: the eye follows the bright arm around and the plain one back.

The oval turned sideways

Set across the finger rather than along it, the oval lies in the same plane as the swirl and becomes part of the curve rather than an object sitting on top of it. It also sits flatter and wider on the hand, and it is far less likely to catch than a north to south stone.

Why an oval reads larger

An oval brilliant carries most of its weight in spread rather than depth, so at a given carat weight it covers more finger than a round. Set east west that extra length runs across the hand, where it is most visible.

What laboratory grown means here

A laboratory grown diamond is a diamond. It is crystallised carbon with the same cubic structure, the same 10 on the Mohs scale, the same refractive index of 2.42 and the same dispersion as a mined stone. Ours are grown by chemical vapour deposition and high pressure high temperature methods, then cut and polished by hand. This is not moissanite, not cubic zirconia and not a simulant. A gemmologist testing it will read diamond, because it is diamond.

Metals

Choose 925 sterling silver, or 10K, 14K or 18K gold in yellow, rose or white. Rose gold is photographed here, and warm metal on the plain arm against colourless pave on the other is exactly the contrast the design depends on. White gold is rhodium plated and will want replating every one to two years.

Every centre stone arrives IGI certified

The centre diamond is graded by IGI, the International Gemological Institute, and the certificate comes with the ring at no extra charge. It states the carat weight, the E colour grade, the VVS2 clarity grade, the measurements and the girdle inscription, and confirms in writing that the stone is laboratory grown. The pave diamonds are matched to the same E and VVS2 grade.

About the bow tie

Every oval has the potential for a bow tie, a dark band across the middle caused by the proportions of the cut rather than by colour or clarity. No certificate grades it. We check each oval by eye and reject the ones that show it.

Made to order in our own workshop

Mapple Gems is a family run workshop in Surat, India, where most of the world's diamonds are cut and polished. The crossover is formed to your finger size so the two arms meet at the right point under the stone, which cannot be adjusted afterwards. Allow two to three weeks for making, plus shipping.

Looking after it

Warm water, mild washing up liquid and a soft toothbrush. Work the brush into the crossing point under the stone and along the pave arm. Take it off for the gym, gardening and swimming.

Questions we are asked

What colour and clarity is the diamond? Every centre stone is E colour and VVS2 clarity, on every metal and every carat weight. The pave stones are matched to the same grade.

Does the carat weight include the pave? No. The 2, 3, 4 and 5 carat options refer to the centre oval. The pave is in addition.

Is the certificate really free? Yes. The IGI report for the centre stone is included in the price on every variant.

Will a wedding band sit flush against it? No, not flat. The crossover means the shank is at a different height on each side, so this ring is designed to be worn alone.

Can it be resized? Only slightly, since resizing changes where the two arms cross. Please measure carefully and we will build to your size.
