Diamond Letter Signets

Men's Classic Square Lab-Grown Diamond Letter Signet Ring in 14K White Gold

$5,615.00

A clean square frame in 14k white gold, the heritage signet silhouette, refined to hold a single custom-cut diamond letter.

14K White Gold stays bright and neutral with the durability of a daily-wear metal.

The center is a single solid lab grown diamond, approximately 2 carats, faceted at the outer edge and left smooth across the center. The letter you choose reveals through the contrast of brilliant cut against unfaceted core. Not engraved. Not cut out. The letter is the stone itself.

Made entirely to order: select your initial in the cart. Each ring is cast specifically for your finger size, and each diamond is custom-cut to render the letter you choose.

Allow 8–12 business days from order to shipment.

Solid 14K white gold, made to last a lifetime.

Your diamond is custom-cut to this letter. Choose carefully; the initial cannot be changed once cutting begins.

The Signature Detail

The letter is not engraved. The letter is the diamond.

Most signet rings carry an initial carved into metal. This one carries an initial made of a single solid lab-grown diamond, cut in the shape of your letter and set into the face of the ring. Nothing is stamped, etched, or filled in.

1

One Diamond, One Letter

Each letter begins as a single lab-grown diamond of approximately two carats. It is custom-cut to the exact shape of the initial you choose, for this ring alone.

2

Faceted Edge, Smooth Core

The outer edge of the letter is brilliant-faceted so it catches light in motion. The center is left smooth, so the letterform reads clearly against the fire of the edge.

3

Cast for Your Finger

The ring itself is cast to your size in our Los Angeles atelier after you order. Diamond and mounting come together as one piece, made for one person.

Built for Every Day

A Signet That Works as Hard as You Do

Solid Metal

14K White Gold throughout. The color and structure run through the entire ring, so fine surface marks from daily wear polish out easily.

Diamond Hardness

Diamond is the hardest material worn as jewelry. A lab-grown diamond is diamond, with the same hardness and brilliance, so the letter holds its polish for a lifetime of handshakes.

Secure Setting

The letter diamond is seated into the face of the signet and secured in the mounting, checked by our quality control before the ring leaves the atelier.

We grow the diamond rough in a lab because that is the only honest way to cut a two carat letter without a six figure price. What you wear is diamond. What you save is the rarity premium of mined rough, which a letter cut does not need.

Questions, Answered

Before You Decide

Is the letter engraved into the ring?

No. The letter is a single solid lab-grown diamond, custom-cut in the shape of the initial you choose and set into the face of the ring. The outer edge of the letter is faceted to catch light and the center is left smooth, so the letterform reads clearly. Nothing is carved into the metal.

How do I choose my letter?

Select your initial from the menu above before adding the ring to your cart. Each diamond is custom-cut to render the letter you choose, so the initial cannot be changed after cutting begins. If you want a letter you do not see listed, talk to a jeweler and we will confirm what our cutters can do.

Is a lab-grown diamond a real diamond?

Yes. A lab-grown diamond is chemically, physically, and optically identical to a natural diamond: the same crystal, the same hardness, the same brilliance. Growing the rough in a lab is what makes a custom-cut letter of this size possible at this price.

What if the size is not right?

Resizing is complimentary within 60 days of delivery. Beyond that window, our atelier still handles resizing for you; talk to a jeweler and we will take care of it. If you are unsure of your size before ordering, start with our ring sizing guide.

How does white gold hold up to daily wear?

White gold is solid gold finished with a bright rhodium surface. With daily wear the rhodium softens over time, and a periodic replating restores the original brightness; it is a quick service our atelier performs. We recommend removing any ring for heavy lifting, but water, soap, and everyday life are not a concern.

How long does it take to make?

Every ring is made to order in our Los Angeles atelier. Allow 8 to 12 business days from order to shipment: the diamond is cut to your letter, the ring is cast to your size, and the finished piece passes quality control before it ships fully insured.

Personalized Guidance

Choosing between silhouettes? Talk to a gemologist.

Every silhouette carries the letter differently. If you are deciding between styles, sizes, or metals, or ordering a gift and unsure of a detail, one conversation settles it. Guidance is always complimentary.
