Our Custom Jewelry Creation Process

Creating your dream piece of custom jewelry at Diamond & Design is as easy as one, two,

Step 1: Collaborative Consultation

Creating a custom piece at Diamond & Design always begins with a consultation. You’ll come into the store, meet with one of our expert designers, and share what you’re looking for in terms
of your design aesthetics and desired feel. We can use any images, sketches, or other pieces of jewelry you find inspiring to narrow in on the details you want for your design. Then, our
designer will work with you to create a sketch of your custom design, keeping in mind both your aesthetic goals and budget.

Step 2: Fine Tuning Your Custom Jewelry Design

Once you approve your initial design sketch, we can start fine tuning your design. At this stage in the process, we will create a CAD rendering of your custom jewelry design. Then, we’ll meet
with you, receive your feedback, and tinker with the design as necessary. We want you to be completely happy with every detail of your design, so there is no limit on how many changes
you can make to the 3D model of your custom piece.

Step 3: Production & Inspection

After you’ve approved your CAD design, we’ll move into the final stage of the design process: production. First, we’ll make a wax model of your design. If you like, you can view your wax
model and check that its fit and look is to your liking. If no changes need to be made, we’ll then  end your design to our jewelry studio for casting and manufacturing. We do multiple quality checks during the manufacturing process, which can take anywhere from one to four weeks. Once your piece is finalized, we do a final inspection before finally presenting you with your
handcrafted, one-of-a-kind piece.
