Jewelry catalog production: consistent renders for every SKU

Consistency is part of the product

Shoppers compare pieces side by side. When one ring is lit warmly from the left and the next is cool and flat, the catalog feels like a market stall rather than a brand. Consistency also saves time: once your look is defined, every new SKU becomes a repeatable task instead of a creative decision.

Renders make consistency far easier than photography. There is no changing daylight, no reflection of the photographer and no setup that drifts between sessions. Lighting, camera and background are presets you pick by name, and the same choices give the same result every time. Your job is to choose them once, write them down and reuse them.

Step 1: Write a shot list per category

Decide which images every product page needs before you render anything. A shot list stops you from rendering twenty angles of one ring and two of the next.

In RenderMyJewels, 40 one-click poses cover standard views such as lay flat, stand up and three-quarter angles. Save any custom angle as a pose so the next SKU uses the same camera angle. The poses and camera page shows the full set.

Step 2: Fix your sizes and aspect ratios once

Every channel wants a different shape. Decide which ones you need and export each shape straight from the studio instead of cropping later:

• Square 1:1 for marketplaces and most shop grids.
• Portrait 4:5 for Instagram feed posts.
• Vertical 9:16 for Reels, Stories and Shorts.
• Wide 16:9 for website banners and YouTube.

The studio offers eight aspect presets with export sizes from 1K up to 8K, plus custom sizes when a channel needs exact pixels. Each export uses one shape and size, and you can export several saved poses of the open model together as a ZIP, so one pass per shape covers the whole angle set. Our marketplace image size guide lists common requirements, and the render resolution calculator helps you pick pixel sizes for print and web.

Step 3: Name and organize files before upload

File names become your filing system. A pattern that starts with the SKU keeps everything searchable later:

SKU_ShortName.ext, for example RG-1042_Solitaire.glb or ER-0301_Halo-Studs.3dm.

When you bulk upload, RenderMyJewels can read the SKU from the start of each file name and use the rest as the model name. Inside the library you can filter by jewelry type, group pieces into collections such as a season or a client, and search by name, SKU or tag. Model library and bulk upload explains the options.

Check layer names inside your CAD files too. Layers or meshes named Diamond, Gem, Stone, Ruby, Pavé or Halo are treated as stones automatically, and everything else starts as metal. Clean names mean fewer clicks per SKU.

Step 4: Lock a house look

Choose one combination and write it down:

• Lighting: one metal lighting environment and one gem lighting environment. The studio keeps the two separate, so diamonds can stay lively without washing out the metal.
• Background: one of the 28 backgrounds, usually pure white or a soft neutral such as light gray or cream for product pages.
• Ground: one of the 10 ground styles, for example a soft contact shadow for a grounded look, or no ground when you want the piece to sit cleanly on plain white, which also suits a background remover later.
• Camera: your saved poses from step 1.

Record these choices in a simple style sheet. When a new team member or a freelancer joins, they can reproduce your look in minutes.

Step 5: Handle colorways with variants

If a design comes in yellow, white and rose gold, render it once and switch materials rather than staging the scene again. Save each colorway as a variant so angles, lighting and background stay identical. Name exports with the variant, for example RG-1042_Solitaire_YG_hero.png and RG-1042_Solitaire_WG_hero.png.

Step 6: Produce in batches

A weekly rhythm works better than rendering whenever a file arrives:

1. Monday: collect approved CAD files and check layer names.
2. Tuesday: bulk upload, then assign jewelry types and collections.
3. Wednesday and Thursday: export the shot list for each SKU and each variant.
4. Friday: quality check, rename and deliver to the shop or marketplace team.

Batching keeps your attention on one task at a time, and that focus is where most of the speed comes from.

Step 7: Name exports so anyone can find them

Use one predictable export pattern:

RG-1042_Solitaire_YG_side_2000.jpg tells everyone exactly what the file is without opening it.

Quality control before you publish

Review every batch against a short checklist:

1. Metal color matches the variant name.
2. Stones look lively but not blown out.
3. The piece sits at the same scale and position as the rest of the category.
4. No stray layers, construction lines or hidden parts are visible.
5. Shadows and backgrounds match the house look.
6. File names follow the pattern.
7. File sizes suit the channel, with large masters stored and web versions compressed.

Keep masters and web versions apart

Export once at the largest size any channel needs and treat those files as masters. Store them in a folder structure that mirrors your catalog, for example by collection and SKU. From the masters, create the smaller web versions each channel needs. When a marketplace changes its requirements or you redesign your store, you resize from the masters instead of rendering everything again.

A practical folder layout:

• masters for the full-size PNG or JPEG exports, one folder per SKU.
• web for compressed JPEG files, or WebP copies converted from the masters, at around 2000 pixels on the long side.
• social for 4:5, 1:1 and 9:16 versions for posts and Reels.
• video for the WebM turntables and multi-angle clips, with MP4 copies made in any free converter for platforms that do not accept WebM.

Working with designers, freelancers and retailers

Catalog production often involves several people. A CAD designer delivers files, someone renders, and a store manager or wholesale buyer uses the images. Make every handover painless:

• Share the style sheet and naming pattern with everyone who touches the files.
• Agree that CAD files arrive with stone layers named and construction geometry hidden.
• Send retailers and wholesale partners images in the sizes they ask for, named with your SKU so they can match them to your price list.
• For new designs that need sign-off, send a share link so buyers can rotate the piece in 3D before you produce images in every format.

When designs change

Designs evolve. When a piece is updated, upload the new file with the same SKU and a version note in the name or tags, export the shot list again and replace the old images everywhere. Move the outdated model to the trash rather than keeping two versions in your library. Deleted models stay restorable for 30 days in case you need the old version back.

Adding AI imagery at scale

Once the core renders are done, AI images add context without a photoshoot. The AI photoshoot places a render on a model's hand, ear or neck, and AI product scenes put it on marble, velvet or a setting you describe. Premium includes 150 AI images and 5 AI videos each month, enough to add on-model shots to your best sellers first and work through the rest over time.

Treat AI images as lifestyle and context. They are generated from your render and keep the design close to it, but check each one against the render before it goes live. Keep your clean renders as the reference images that show the exact design.

Keep the system alive

A catalog system only stays consistent if it is written down. Keep the style sheet, the shot list and the naming pattern in one shared document, and update it when you change your look. When you refresh the whole catalog, for example for a rebrand, update the style sheet first, then open each model, apply the new look and export the shot list again, so every piece changes in the same way. Our page on catalog production shows how the studio supports this at scale.
