It depends on whether you'd like a completely custom piece from scratch or customization of an existing piece. If you are interested in placing a completely custom order, we will require an initial $100 deposit (that will go towards the ring) to create the CAD to confirm or fine-tune your design as well as start the stone sourcing process. Once you approve the CAD, we will then ask for a 50% deposit before starting the production, with the remaining 50% due upon completion of the ring. If you want to customize an existing piece from our inventory, such as changing the number of prongs or the carat size of the gemstone - as an example, there will be no additional charge unless significantly more materials are required.
