Diamond Personalizer for Custom Jewelry: Stone Swatches, Upgrade Pricing and Honest Disclosure

What a diamond personalizer needs to do

Four jobs, in this order.

1. Make origin unmissable. Natural and lab-grown look the same to the eye and price very differently. The choice has to be explicit and the label has to be right.
2. Limit choices to stock you can get. Every shape and carat you list is a promise. Don't show a 2 ct marquise if your supplier can't deliver one in your turnaround time.
3. Price each upgrade clearly. The customer should see the base price with your smallest stone, then each upgrade as its own amount.
4. Save every choice on the order. Your setter needs origin, shape, carat band and any grade or report choice in writing, on the line item.

Stone choices as swatches

Swatches beat dropdowns for stones because shape is visual. Most buyers can't picture "cushion" or "radiant" from the word alone.

Origin. Two swatches: "Natural diamond" and "Lab-grown diamond". Use the same photo style for both, and put the label on the swatch itself, not only in a tooltip.

Shape. Offer the shapes your settings actually hold. A common set for solitaires is round, oval, princess, cushion, emerald, pear and marquise. Use a clean top-down image of each cut as the swatch.

Carat band. A dropdown works here: 0.25 ct, 0.50 ct, 0.75 ct, 1.00 ct, 1.50 ct, 2.00 ct. Bands are easier to source and price than exact weights. Say "approximate carat weight" if you ship within a range.

Quality tier (optional). If you buy stones in grades, offer two or three named tiers that map to real colour and clarity ranges, and list those ranges in the description.

Accent stones on a halo or band are usually not a choice. Describe them in the product copy, with total carat weight, and keep the personalizer for the centre stone.

Fields to offer, with pricing logic

Diamond prices move with the market and with your supplier, so the table shows the pricing method rather than fixed numbers. Set every amount from your cost plus your margin, and review it at least monthly.

The big decision is the carat list per origin. A lab-grown 1.00 ct and a natural 1.00 ct can be priced far apart, so one carat dropdown with one price list will be wrong for one of them. On the Pro plan ($13.99/mo), conditional logic shows a different carat dropdown depending on which origin swatch is picked, each with its own add-on prices.

Keep the base price honest. If the product photo shows a 1 ct look but the base price is for 0.25 ct, say "from" on the price and "shown with 1.00 ct" under the photo.

What the preview should show

PIMW shows a live 2D preview on your own product photo. For diamond jewelry, that preview is most useful for the parts that change visibly in 2D: the metal colour and any engraving text.

It doesn't render diamonds in 3D or change a stone's size on the photo, and we don't suggest faking that. The FTC Jewelry Guides include a section on misleading illustrations, and a photo that shows a bigger or different stone than the one ordered is exactly that risk.

What works in practice:

• Use a shape swatch image for each cut, so the customer sees the shape they picked.
• Photograph the setting with each shape you sell if you can, and name the photo by shape.
• Put a line under the photo: "Shown with a 1.00 ct round. Your stone matches your selections."
• Show the engraving on the band or pendant back in the font they picked.

Disclosure and certification wording

This is where diamond stores get into trouble, so be precise.

Lab-grown wording. Under the FTC Jewelry Guides, the approved qualifiers are "laboratory-grown", "laboratory-created" and "[company name]-created". The qualifier should sit immediately before the word "diamond" and be as prominent as the rest of the description. "Synthetic" was removed from the approved terms in the 2018 revision. FTC warning letters to lab-grown sellers also flagged ads where the disclosure was missing or buried.

In your personalizer that means:

• Swatch label: "Lab-grown diamond", never "diamond" alone.
• Cart and order: the line-item property reads "Stone: Lab-grown diamond, oval, 1.00 ct".
• Never call a lab-grown stone "real", "genuine", "natural" or "mined", and don't let "Diamond" stand alone in a title for a lab-grown piece.
• If you sell moissanite or cubic zirconia, name them as what they are. They are not diamonds of any kind.

Certification wording. Name the lab and the report type, and only promise what ships.

• GIA, natural diamonds. Full colour, clarity and cut grading.
• GIA, lab-grown diamonds. Since October 1, 2025, GIA issues a Laboratory-Grown Diamond Quality Assessment that describes qualifying stones as "Premium" or "Standard" rather than using the D-to-Z and clarity scales. Stones are laser-inscribed "Laboratory-Grown" with the assessment number, and the minimum submission size is 0.15 ct.
• IGI. Widely used for lab-grown stones and issues reports with colour and clarity grades.

So "GIA-graded G VS1" is right for a natural stone and wrong for a lab-grown stone graded after October 2025. Write the swatch or tier descriptions to match the report you actually ship.

How to set it up in PIMW

1. Install PIMW Product Personalizer. The Free plan covers your first product.
2. Add the app block to your diamond product template in the theme editor.
3. Create the origin swatch with two options and clear labels.
4. Add the shape swatch with one image per cut you can set.
5. Add a carat dropdown for each origin, with add-on prices per option.
6. On Pro, set conditional logic so each carat list shows only for its origin.
7. Add metal swatches and the optional engraving field with a character limit.
8. Write the "shown with" line and the report wording in your product description.
9. Place a test order and confirm the order shows origin, shape, carat, metal and engraving as separate line-item properties.

Add-on fees appear as their own cart line, and there's no per-sale fee, which matters when a single order runs into four figures.

Common mistakes

• "Diamond" with no qualifier on a lab-grown piece. Put "Lab-grown" on the swatch, the title and the order line.
• One carat price list for both origins. Use separate lists so neither is mispriced.
• Listing stones you can't source. Remove shapes and carats your supplier can't deliver on time.
• Photos that oversell. A 2 ct photo on a 0.25 ct base price needs a "from" price and a "shown with" line.
• Promising GIA colour and clarity grades on new lab-grown reports. Match your wording to the report.
• Eco claims you can't back. The FTC has objected to unsupported "eco-friendly" and "sustainable" claims on lab-grown stones.
