Oval Cut Lab Grown Diamond Ring with a Cathedral Setting and a Pave Gallery Arch

Oval Cut Lab Grown Diamond Ring with a Cathedral Setting and a Pave Gallery Arch

An oval cut lab grown diamond in four claws over a pavé set hidden halo, carried on cathedral shoulders that sweep up to meet the head, with a pavé set gallery arch spanning the space beneath the stone and a completely plain band.

A cathedral setting takes its name from the two arms of the shank rising in a curve to meet the head, the way a vaulted arch rises to meet a keystone. It is not only a shape. Those arms are structural, bracing the head from both sides and carrying the load into the shank instead of concentrating it at a single joint, which is why a cathedral is the sturdier way to mount a large stone. Rising also lifts the head slightly, which leaves clearance for a wedding band to sit flush underneath rather than knocking against the pavilion. Under the stone, spanning between those two rising arms, is a gallery arch, and it has been pavé set with small round diamonds rather than left as a plain bar of metal. That arch does the same job as a plain gallery wire, tying the two sides of the head together and stopping any flex at the claws, but it also catches light coming in from underneath and throws it up into the pavilion. Everything else is left alone. The band carries no pavé, no engraving and no milgrain, with only a shallow hollow worked into each shoulder to lighten it.

A plain polished shank whose two arms rise in a cathedral curve to meet the head, with a shallow hollow worked into each shoulder. No pavé, engraving or milgrain on the band. The interior is smooth and comfort rounded.

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 rising cathedral arms hold a long bright highlight that reads clearly against the small white stones in the arch.

We can change the carat weight, add pavé along the cathedral arms, leave the gallery arch plain, remove the hidden halo, or make a matching plain wedding band that sits flush beneath the head.

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 a cathedral setting
The two arms of the shank rise in a curve to meet the head, like a vault rising to a keystone. They brace the head from both sides and carry the load into the shank, which makes it the sturdier way to mount a large stone.

Will a wedding band sit flush against it
Yes. The cathedral rise lifts the head enough that a band sits underneath without hitting the pavilion, which is one of the main practical reasons for the design.

What does the pave gallery arch do
It ties the two sides of the head together and stops any flex at the claws, exactly as a plain gallery wire would, and because it is set with diamonds it also catches light coming in from beneath and returns it into the stone.

How is this different from your other gallery wire ring
Our other gallery wire design is on a knife thin band with half coverage scalloped pavé on the shank. This one is a cathedral with a pavé set arch and a completely plain band.

Why are the shoulders hollowed
A shallow hollow removes weight from the widest part of the shank without narrowing its visible width, so the ring keeps its presence while sitting lighter on the finger.

Can this ring be resized
Yes, comfortably. The band is plain and unset, so a sizing cut disturbs nothing.

Why buy a lab grown diamond

All of the detail in this ring is structural, in the arch and the collar, so the centre stone is what you actually look at. Lab grown material is how an E colour VVS2 oval of two to five carats with excellent cut and polish sits above a plain band at this price, with a traceable origin and no mining.
