SKU (Stock Keeping Unit)
Also called stock keeping unit, product code
A SKU is a code that identifies one exact product variation in a store, down to the metal, the stone, and the size. Two rings of the same design in yellow and white gold are two SKUs, and each one needs its own set of images.
In other words, it is the internal product code for one precise version of an item, not for the design as a whole.
How SKUs multiply in jewelry
Jewelry ranges expand fast. One solitaire design offered in three metals, four stone sizes, and a run of finger sizes is already dozens of codes, and each of those codes is a row in your catalog that a shopper can land on directly.
That is a photography problem before it is a data problem. Shooting every variation means every variation has to physically exist first.
- Metal: rose, white, yellow gold
- Stone type, shape, and carat weight
- Setting style
- Finger or chain size
Why SKU imagery has to be consistent
A category page shows many SKUs side by side. If they were shot on different days, the backgrounds drift, the highlights sit differently, and the grid looks like it was assembled from several stores. Shoppers read that as low quality.
Renders are consistent by construction. The same lighting setup and the same camera angles apply to every file, so the fiftieth SKU matches the first exactly. Every piece comes back on a white background, ready to sit in a grid.
Covering metal variations without reshooting
One CAD file returns 9 HD images and 3 videos in rose, white, and yellow gold. That is three metal SKUs covered from a single file, at one flat price of $15 per file (regular $30, a launch offer).
For a catalog build, send the files in batches. Standard turnaround is 24 to 48 hours per file, with two revision rounds included, and an NDA is signed before your files are opened.
Questions about SKU
Do I need separate images for every jewelry SKU?
Yes, if the variation is visible. Metal colour and stone shape both change what the shopper sees, so each of those needs its own image set. One CAD file rendered with us covers the three gold colours.
How much does it cost to render a full catalog?
It is $15 per CAD file (regular $30, a launch offer), and each file returns 9 HD images and 3 videos. So the cost scales with the number of designs, not the number of SKU codes.
Will renders of different SKUs match each other?
Yes. Every file goes through the same lighting and camera setup, so a category grid stays consistent no matter how many pieces you add later.
