Best AI tool for accurate jewellery mockups? (Most distort design — need suggestions)

Hi all,

I’m trying to create AI jewellery mockups (with and without models), but most tools end up changing the jewellery’s size, shape, or design — especially in on-model shots.

The only tool that has worked well so far is NanoBanana Pro — pretty accurate, but it requires uploading multiple models + mockup references each time. However this is really good with the nano banana pro version.

Any recommendations for AI tools that can:

Keep exact jewellery dimensions/design

Generate product-only + on-model mockups

Ideally support high-res and batch exports

Would really appreciate recommendations from people who’ve tried this in a jewellery workflow. Thanks! 🙏
