Elongated Radiant Cut Lab Grown Diamond Ring in Yellow Gold with a Mitred Concealed Halo

Elongated Radiant Cut Lab Grown Diamond Ring in Yellow Gold with a Mitred Concealed Halo

An elongated radiant cut lab grown diamond in four claws, with a concealed halo running along all four walls of the basket, on a fine yellow gold shank set with a single row of pave.

A concealed halo under a round or an oval is a simple job, because the basket is a continuous curve and the small stones can be seeded around it at even spacing until they meet. Under a rectangle it is a different problem. The wall consists of four straight runs meeting at four corners, and at every corner the setter has to decide whether to mitre the two runs together, leave a gap, or drop a stone into the corner itself at an angle. This ring mitres. Each straight run is set to within one stone of the corner, and the corner then takes a single smaller diamond seated at forty five degrees so its girdle meets both runs squarely. It is the only arrangement in which the halo reads as continuous from every side rather than as four separate rows that happen to be near each other, and it is the reason the profile of a rectangular stone rarely looks as resolved as this one.

Band details

The shank is fine and slightly domed, with pave on the top face only and the lower half left plain. Keeping the band narrow is deliberate, since an elongated centre stone looks longest when the metal beneath it is at its thinnest.

Metal options

Choose 925 sterling silver, or 10K, 14K or 18K gold in yellow, rose or white. Every metal is fully hallmarked. Yellow gold is shown in the photographs, where the warm basket gives the concealed halo a distinctly golden edge in profile.

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.

We can change the carat weight, alter the length to width ratio of the radiant, remove the concealed halo, or leave the shank plain. 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, hardness and optical behaviour as a mined diamond and is graded on the same scales.

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

What does mitred mean here
The four straight runs of the concealed halo meet at the corners through a single stone seated at forty five degrees, so the halo reads as one continuous line rather than four separate rows.

What is an elongated radiant
A radiant cut with a longer length to width ratio than the standard, which makes the finger look longer and gives a larger face up spread.

Does a radiant sparkle like a round
Close to it. A radiant uses brilliant style faceting inside a rectangular outline, so it is far livelier than an emerald cut of the same shape.

Can this ring be resized
Yes. The lower half of the shank is plain, so resizing does not disturb the pave.

How long does the ring take to make
Each ring is made to order. Production usually takes twelve to sixteen working days before dispatch.

Why buy a lab grown diamond

Elongated shapes are cut from rough that a round would waste, and lab grown material lets that be done without paying a scarcity premium. You get a larger stone and a higher colour and clarity grade for the same budget, with a traceable origin and no mining.
