East West Elongated Cushion Lab Grown Diamond Ring with a Hidden Halo on a Cathedral Shank

East West Elongated Cushion Lab Grown Diamond Ring with a Hidden Halo on a Cathedral Shank

An elongated cushion cut lab grown diamond turned sideways across the finger, lifted on a cathedral shank, with a hidden halo of small diamonds wrapping the basket beneath it. The arms of the shank rise from the band in two curved arches and meet the setting at its base, the way the buttresses of a cathedral meet a wall, which is where the name comes from.

A cathedral shank is not just a shape. Those rising arms carry some of the load that would otherwise sit entirely on the claws, which matters when the centre stone is four or five carats. They also lift the stone clear of the finger so light can reach it from below, and they give the ring real height in profile without making the band itself any thicker. Turning the cushion east to west then does the opposite of what most settings do, spanning the width of the finger instead of running along it, which is what makes a large stone look wide rather than long.

Band details

The shank is a plain polished band through the base that divides into two arched arms at the shoulders, sweeping up to support the head. The inside is rounded and smooth, and because the arms carry the height rather than the band itself, the ring stays comfortable to wear.

Metal options

Choose from 925 sterling silver, or 10K, 14K and 18K gold in yellow, rose or white. Yellow gold is shown here and it makes the arch of the cathedral read clearly against the hand, which is the point of the profile. Rose gold gives a warmer, softer version. White gold and sterling silver make the whole structure recede so only the stone and the hidden halo register.

Frequently asked questions

What is a cathedral shank?
It is a band whose shoulders rise in two arches to meet the setting, rather than running flat into it. The arches support the head, lift the stone and give the ring height in profile.

Why set a cushion east to west?
Turned sideways the stone spans the width of the finger, which makes it look broader and gives the ring a modern, less conventional line. Set north to south the same stone lengthens the finger instead.

Does the cathedral setting make the ring less comfortable?
No. The band itself stays the same width and the inside is rounded. The height is carried by the arms above the finger, not by extra thickness against it.

What is a hidden halo?
A ring of small diamonds set around the basket beneath the centre stone. It cannot be seen from above, so the ring keeps a clean outline, but it adds brightness and shows as a surprise from the side.

Is a lab grown diamond a real diamond?
Yes. A lab grown diamond has the same carbon crystal structure, hardness, refractive index and fire as a mined diamond. The only difference is that it was grown in a controlled environment rather than pulled from the ground.

Will I receive a certificate?
Yes. An IGI certificate for the center stone is included with every order at no additional cost.

Will a wedding band sit flush against this ring?
A straight band will sit against the base of the arch with a small gap under the head. We can make a contoured band that follows the cathedral line if you want the two to sit flush.

Why buy a lab grown diamond

A lab grown diamond gives you the same optical and physical properties as a mined stone at a far better price for the size and quality. Because the growth conditions are controlled, high color and high clarity stones like the E VVS2 used here are available in large carat weights that would be rare and costly in mined goods. It is also a traceable choice, with a known origin and no mining footprint.
