The piece
About this design
Equal sides, softly rounded corners, and a plain band underneath: this is the most architectural ring in the range and the least fussy. A square cushion sits squarely on the finger rather than stretching along it, so it reads as balanced and considered rather than showy — and with no texture or pavé anywhere, that geometry is the whole point. It also stacks beautifully, because a straight shank and a symmetrical stone never sit at an angle.

Before you order
Questions about this piece
The things customers ask us most about this exact design.
A standard cushion is slightly longer than it is wide; a square cushion has equal sides. If you like the soft vintage warmth of a cushion but want a cleaner, more geometric outline, this is the one.
One of the best here. The plain straight shank sits perfectly flat and the symmetrical stone will not tilt, so wedding bands and stacking rings line up cleanly on both sides with no gaps.
No. They are rounded rather than pointed and every one sits under a prong, which is the most protected position on any stone. This is a shape made for constant wear.
Chemically and optically identical, IGI certified. Because we cut out the middlemen and make each ring to order ourselves, the same spend buys a distinctly larger stone.
It does the reverse. With nothing else on the ring, the stone carries it entirely — which is why plain-band solitaires are what most people picture when they think of a serious diamond ring.
Every piece is made to order in our own workshop — solid 10K, 14K or 18K gold, 925 sterling silver or platinum, never plated — and set with IGI certified lab grown diamonds. Because we sell directly with no middlemen, you get true fine-jewelry quality at a fair price, backed by free worldwide shipping and easy 30-day returns.

Proof, not promises
Everything here can be checked
Anyone can call a diamond certified. What matters is whether you can go and confirm it somewhere that is not us — so every claim below is one you can test yourself.
A lab grown diamond over 1.00 carat ships with its own IGI report. Accent stones and moissanite are not certified.
-
01
The centre stone is graded by someone other than us
A lab grown diamond over 1.00 carat goes to IGI — an independent gemological laboratory — and is graded there, and its report ships with the piece. Below that weight the accent stones are not individually certified; nobody in the trade certifies melee. We would rather tell you that here than let you open the box expecting paperwork that was never coming.
-
02
Check the report against IGI's own database
If your piece came with a report, type its number into IGI's site. It will show you the same stone, graded on the same date. If it does not match what arrived, you did not get what you paid for — and you have thirty days to send it back.

03
Grown, not mined — and we say so everywhere
A lab grown diamond is a diamond: same carbon lattice, same hardness, same fire, and it passes a diamond tester exactly like a mined stone. The only difference is where it formed. You will never find that fact buried in the small print here.
-
04
Solid metal, all the way through
10K, 14K or 18K gold, 925 sterling silver or platinum — solid, never plated over brass. Plating wears through in months and takes the colour with it. Weigh it, test it, or send it to a jeweller.

05
Cut, set and finished at our own bench
Every ring is made to order at our own bench, not bought in finished and relabelled. That is why we can move a stone, change a shank profile or cut a size we do not list — a reseller could not.

Thirty minutes on a call, free, no obligation to buy. Bring a screenshot of something you saw elsewhere and we will tell you honestly whether ours is the better stone.

In their words
What customers say
Unedited, and left by people who actually paid for the piece.
No one has reviewed this exact piece yet
It is made to order, so it is new to the catalogue. Rather than fill this space with reviews written about other pieces, we have left it honest — the photographs on this page were all sent in by customers, and our reviews page has what buyers have said about Driona itself.
-
Verified purchases
Requests go out to the order after it ships, so a review means someone was actually sent the piece.
-
The bad ones stay up
We do not delete low ratings. If something went wrong you should be able to read about it here before you order.

Photos welcome
A photo on a real hand in real light tells you more about a stone than any of our studio shots can.
