Oval Cut Lab Grown Diamond Three Stone Ring with Round Sides and a Concealed Halo

Oval Cut Lab Grown Diamond Three Stone Ring with Round Sides and a Concealed Halo

An oval lab grown diamond in six claws with a round brilliant on each side, above a concealed halo that runs beneath the centre stone only. The shank is plain and slim, so the three stones sit as a single group with nothing beyond them.

Getting the side stone size right against an oval is a specific calculation rather than a matter of taste. An oval narrows continuously from its widest point toward each end, so at the place where a side stone touches it, the centre diamond has a particular width and the two shapes have to agree there. Choose a round that is too small and a wedge of daylight opens between the two stones where the oval's curve pulls away. Too large, and the round stands proud of the oval's shoulder and breaks the outline into three separate circles. The size that works is the one whose diameter matches the width of the oval at the point of contact, which for our proportions falls at roughly a third of the centre stone's width. Set to that number, the three stones form a single continuous outline that narrows and widens once, and the eye reads a shape rather than a row. The concealed halo is then deliberately restricted to the centre stone: extending it under the sides would thicken the two smaller heads and break the line the sizing was chosen to create.

Band details

The shank is slim, plain and rounded, stepping down immediately beyond the side stones. Leaving it undecorated is what allows the three stone group to read as one outline rather than as the start of a longer run.

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 claws mark the junctions between the three stones without interrupting them.

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, and we recalculate the side stone diameter for each centre stone weight.

Custom orders

We can change the carat weight, the length to width ratio of the oval, substitute pear or trillion sides, or extend the concealed halo. 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 is carbon in the same crystal structure as a mined diamond, with the same hardness and the same optical properties, 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.

How are the side stones sized
Their diameter is matched to the width of the oval at the point where the two stones touch, which is roughly a third of the centre stone's width. That is what closes the join and keeps the outline continuous.

Why does the concealed halo stop at the centre stone
Extending it under the side stones would thicken their heads and break the single outline the sizing was chosen to create.

What do the three stones represent
Traditionally the past, the present and the future, which is why three stone rings are chosen for anniversaries as often as for engagements.

Can this ring be resized
Yes. The shank is plain, so resizing is done in clean metal.

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

A lab grown diamond gives you a larger stone and a higher colour and clarity grade for the same budget, with a traceable origin and no mining. In a three stone ring it also means all three can be grown to the same colour, which is difficult and expensive to match with mined stones.
