Oval Cut Lab Grown Diamond Three Stone Ring with Emerald Cut Side Stones

Oval Cut Lab Grown Diamond Three Stone Ring with Emerald Cut Side Stones

An oval cut lab grown diamond in six claws with a rectangular emerald cut diamond claw set on each side, laid east to west across the finger, on a plain tapered band.

Pairing a brilliant cut centre with step cut sides is the most architectural way to build a three stone ring, and it works because the two cuts do completely different things with light. The oval is a brilliant, faceted into dozens of small triangles and kites that scatter light into rapid flashes. The emerald cuts beside it are step cuts, faceted into long parallel planes that behave like mirrors, returning broad slow flashes of white and dark rather than sparkle. Set next to each other, the sides read as calm rectangles of light framing a bright centre, which makes the oval look livelier than it would flanked by two more brilliants. The sides are set east to west, their long axes crossing the finger rather than running along it, so their straight edges square off against the curve of the oval and give the whole head a clean architectural outline. Step cuts are also the least forgiving cut in jewellery. With no facet noise to hide behind, any inclusion or tint sits in plain sight, which is why side stones like these are usually the most expensive part of a mined three stone ring.

Metal options

Choose 925 sterling silver, or 10K, 14K or 18K gold in yellow, rose or white. Every metal is fully hallmarked. White gold is shown in the photographs, where the neutral metal keeps the step cut sides looking cold and clean.

Ring size

The ring is made to your finger size. Select your size at checkout. If you are unsure, we will send you a printable size guide before we begin work.

Custom orders

We can change the carat weight, set the emerald cuts north to south instead, substitute tapered baguettes or trapezoids, add a hidden halo, or set pave along the shank. Write to us through https://mapplegems.com/pages/contact and our workshop will prepare a quotation and a rendering before any metal is cut.

Frequently asked questions

Is a lab grown diamond a real diamond
Yes. It has the same carbon crystal structure, the same hardness of 10 on the Mohs scale and the same optical behaviour as a mined diamond, and it is graded on the same scales by the same laboratories.

Does the ring come with a certificate
Yes. An IGI certificate for the center stone is included at no extra charge.

What is the difference between a brilliant cut and a step cut
A brilliant is cut into many small triangular and kite facets that scatter light into fast sparkle. A step cut has long parallel facets that act like mirrors, giving broad slow flashes. The oval here is brilliant, the sides are step cut.

Why pair the two
Contrast. Calm rectangular sides make the brilliant centre look livelier, and the straight edges of the emerald cuts square off against the curve of the oval so the head has a defined outline.

Why are the side stones set east to west
So their long axes cross the finger. It widens the head, gives the design its architectural look and stops the three stones reading as one long line.

Do step cut diamonds show inclusions more
Yes, considerably. There is no facet pattern to hide behind, which is why we select the sides eye clean rather than simply to a clarity grade.

Does this ring sit flush with a wedding band
Yes. The shank is straight and unset, so a plain or pave band meets it cleanly on both sides.

How long does the ring take to make
The three stones are matched for colour and the step cut sides are aligned by hand so their facet lines run parallel, so allow eighteen to twenty two working days before dispatch.

Why buy a lab grown diamond

Step cut side stones matched to a large brilliant centre are among the hardest things to source in mined goods, because any tint or inclusion shows through the open facets. Lab grown material lets us cut all three stones to one grade from the same run, with a traceable origin and no mining.
