1. Who is my point of contact? A good custom jewelry manufacturer assigns a single coordinator so you are not repeating instructions to different people or chasing updates across departments.

2. What does your process look like? Ask them to walk you through jewelry product development from sketch to finished piece, so you know what happens at each stage and when your input is needed.

3. How do you handle revisions? Confirm that you can review and adjust the 3D model before anything is produced, since changes are far easier at that point.

4. How do you keep a collection consistent? For multiple pieces, ask how they make sure each unit matches the approved design.

5. What happens after delivery? Ask about quality control and any warranty that covers maintenance or sizing down the line.

Getting clear answers upfront tells you a lot about how a studio works and whether the experience will feel organized or chaotic.
