The Cushion Pin
From clients
“Catherine is someone who not only works with morals, integrity and ethics, but she has amazing pricing and helped me find a unique loose diamond that beat the price of every quote I got from other retailers.”
“My fiancée wanted her ring unique, elegant, and to stand out without being flashy — and we hit all three. I couldn’t have found anything like this anywhere else. The blue diamond is going to blow her away.”
“The charms themselves are stunning — delicate, sparkly, and beautifully made. They catch the light in such a pretty, subtle way, and the different cuts give each one its own personality.”
A 1-carat cushion-cut lab diamond — DEF color, VS clarity — set in a sterling silver milgrain bezel with a traditional clutch back. It’s built to go where a pin naturally goes: a leather jacket lapel, a denim collar, a silk scarf, the strap of a bag you love. A fine-jewelry object that operates the way an enamel pin does — portable, personal, and unmistakably yours to move.
You approve the design mockup before we engrave the diamond.
Every monogram is reviewed by hand against the actual diamond dimensions. If letter spacing or overlap needs adjusting, we email you a revised mockup before any engraving happens. No surprises.
How it works
- Design your monogram. Pick a single initial, two-letter combination, or three-letter monogram — or no monogram at all — in serif, sans serif, or script. Preview in the customizer before adding to cart.
- Add to cart. One size, one material — solid sterling silver (.925).
- We hand-review your design. Within 3–5 business days of your order, we check letter spacing, overlap, and proportions against the diamond. If anything needs adjusting, we’ll reach out before proceeding.
- Your pin is engraved and shipped. 4–5 weeks from your final design approval, fully insured with signature required.
The Object
- Name: The Cushion Pin
- Silhouette: Cushion-cut bezel-set pin with traditional clutch back
- Edition: Made to order
- Collection: Monogram Diamond
- Inscription: Single initial, two-letter combination, or three-letter monogram — or no monogram, for a plain diamond bezel pin. Scripts: Serif, Sans Serif, or Script — preview in the customizer before ordering.
- On the preview: The monogram shown in the customizer is a digital approximation. Before your pin goes to inscription, every monogram is reviewed by hand — letter spacing, overlap, and overall balance checked against the actual diamond dimensions. If anything needs adjusting, we’ll reach out before proceeding.
The Stone
- Type: Lab-grown diamond
- Cut: Cushion (classic square cushion)
- Carat weight: approximately 1 ct (pictured piece is 1.01 ct; made-to-order stones fall within ±0.02 ct of that weight)
- Color: DEF (colorless — top three grades on the GIA scale, visually indistinguishable from one another)
- Clarity: VS (very slightly included — inclusions not visible to the naked eye)
- Dimensions: 5.57 × 5.48 × 3.82 mm (pictured piece; made-to-order stones will fall close to 5.5 × 5.5 mm)
- Accent stones: None
Specs describe the pictured piece. Made-to-order stones will match its weight, color grade, and clarity grade within the ±0.02 ct margin above.
The Metal
- Metal: Solid sterling silver (.925)
- Setting: Milgrain bezel
- Back: Traditional pin post with butterfly clutch
- Finish: High polish
Sterling silver tarnishes. This is what the material does when it oxidizes in contact with air and skin — it happens to every sterling piece regardless of quality. A polishing cloth removes it in under a minute. Sterling is not a lesser setting for this diamond. The stone is the piece. The silver holds it.
Measurements
- Stone dimensions: 5.57 × 5.48 × 3.82 mm
- Bezel diameter: Approximately 7 mm across (bezel walls add roughly 0.7 mm on each side of the stone)
Provenance & Certification
- Stone sourcing: Lab-grown, sourced to order
- Certification: IGI certified. Original certification ships with every pin.

Care
Sterling silver is durable and takes a polish beautifully; it will develop a soft patina over time and can tarnish with skin and air contact. A polishing cloth restores it in under a minute. When not being worn, store the pin flat in a soft pouch or lined box to slow tarnishing. Avoid direct contact with harsh chemicals including chlorine, bleach, and acidic cleaners. Complimentary cleaning, polishing, and inspection within the first year of purchase — see our Warranty & Repairs page for full coverage details.
Common questions
What if I don’t like the mockup you send me?
You can request adjustments to letter spacing, style, or size, and we’ll send a revised mockup. Nothing is engraved until you approve the final design. If after adjustments you want to cancel, email cp@catherinepeck.com and we’ll work through it.
How long does the whole process take?
Roughly 4–5 weeks from your final design approval: 3–5 business days for our design review, then 3–4 weeks for stone sourcing, engraving, and finishing.
Where can I wear this?
Anywhere a pin lands right. A leather jacket lapel, a denim collar, a silk scarf, the strap or flap of a bag, a hat brim. Traditional lapel or tie use works too — but the pin is deliberately built to feel modern, not stuffy.
Is the engraving visible when I wear it?
Yes. The monogram is laser-etched onto the table (top facet) of the diamond, so it reads clearly at close range and shimmers into the light at a distance. Signal, not shout.
What if I want more than three letters, or a symbol?
Three letters is our standard. For longer inscriptions, dates, or symbols, email cp@catherinepeck.com before ordering — we’ll confirm what’s possible on the stone dimensions and quote any custom work.
Do I get certification with the diamond?
Yes. IGI certification for the center stone ships with every pin.
