Round Cut Lab Grown Diamond Ring with an Asymmetric Marquise Crown Halo

Round Cut Lab Grown Diamond Ring with an Asymmetric Marquise Crown Halo

A round brilliant lab grown diamond inside a close halo of round accents, with a crown of marquise cut diamonds fanning outward from one side only, on a fine plain band.

Almost every halo ring is symmetrical, and symmetry is what makes most of them interchangeable. Setting the outer row on one side only turns the head into a shape rather than a circle, and gives the ring a direction on the finger. The marquise stones are laid with their points facing outward and stepped in length so the fan rises to a peak and falls away, which is a construction borrowed from tiara work of the early twentieth century. Because the crown sits on one flank, a wedding band can sit flush against the open side, which a full double halo makes impossible. It also means the ring photographs and reads completely differently depending on which way it is turned, and the wearer can rotate it so the fan points along the finger or across it.

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 marquise crown reads as a spray of light against the skin.

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, mirror the crown to the other side, make it symmetrical on both sides, or remove it entirely. 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 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.

Why is the crown on one side only
It gives the ring a direction and a silhouette rather than a circle, and it leaves the other side open so a wedding band can sit flush.

Can the crown be set on the other side
Yes. Tell us which way you would like it to face and we will make it that way at no extra cost.

Are marquise accent stones fragile
Their points are the thin part, which is why each is set with metal folded over the tip rather than a plain bead.

Can this ring be resized
Yes. The band is plain and carries no stones.

How long does the ring take to make
Each ring is made to order. The graded marquise crown is slow work, so allow sixteen to twenty working days before dispatch.

Why buy a lab grown diamond

A design like this needs marquise accents and round accents to match a large centre stone in colour, which is difficult with mined goods. Lab grown material lets us hold one grade across every stone, with a traceable origin and no mining.
