The Process of Bespoke Jewellery Design

As unique as your other half, our approach to jewellery design gives you the opportunity to create a one-of-a-kind, distinctive piece you can treasure for life.

To start the process, we’ll need to know a bit more about what you are looking for – things like design ideas, metal choice and stone shape. If you’re not sure, check out the Getting Started and Inspiration sections below.

After we have discussed all the options and decided on what you want, we’ll source an exceptional selection of diamonds or gemstones and send you a few options in the form of a quote.

Once you have selected a preference and accepted the quote, we’ll start the design and manufacturing process. From this point to completion, it usually takes about 2–3 weeks. When the final product is finished, we safely package and send it to wherever you are in the world.
