Made for independent jewelers.
Built by people who know the work.
Caratwise was created to help independent jewelers sell custom with more confidence - by giving you the ability to design freely, price instantly, and deliver confidently.
Why Caratwise exists
Independent jewelers are being asked to deliver a more modern custom experience — faster, more visual, and easier to follow — without losing what makes them special. Caratwise was built to support that reality: help you guide the customer confidently, keep details organized, and move from approval into production with fewer handoffs.
It's not about replacing the jeweler. It's about helping jewelers thrive.
