When is iJewel3D the better choice?
- You want 3D viewers, ring and wedding band configurators and AR try-on on your web shop, under your own brand on their Professional plan.
- You sell a range built from a library of components, and want customers to configure a ring with prices set by your rules.
- Your developers want a web viewer SDK, or diamond rendering in Unity or PlayCanvas.
- You want a large catalogue rendered in batches by a desktop app (iJewel BatchX).
When is Jart a better fit than iJewel3D?
- You want path-traced stills and turntables of your own CAD file, made in the browser tab on your own graphics card, with no plan limit on renders.
- You want unreleased designs to stay in your browser until you choose to share them; a hosted viewer keeps the model on the host's servers.
- Facts and casting checks. Design Facts weighs the metal in each alloy, counts the stones with their carat and reads the ring size; the cast check (Pro) looks at wall thickness, prongs and seats.
- A record from approval to the shop. An approval keeps a SHA-256 fingerprint of the exact files; the caster pack carries the metal STL, the facts and a fingerprint of every file; a Piece Passport page records the finished piece; Copy for Shopify puts the facts on a product page (Pro).
- An API and MCP server. Scripts and AI assistants measure a file's metal weight, stones, ring size and cast check, and check whether it is the version a client approved (Developers, Pro).
Can you use Jart alongside iJewel3D?
They fit together: design, measure and get the approval in Jart, then show the finished piece on your shop with iJewel3D's viewer or configurator. If a 3D viewer of the approved file is all your shop needs, Jart's Copy for Shopify (Pro) makes a product CSV with the facts, a true-size GLB and USDZ for AR, and the embed.
