Jewelry Custom Design & Manufacturing

Let our design experts help create your fantasy piece from drawing to completion in as little as two weeks. Our experienced team will assist you through the custom design process beginning with collaboration on design ideas to a beautifully finished keepsake piece. With our state-of-the-art wax making and casting capabilities, we can ensure quality and fast delivery. All jewelry custom design work is done on-site and you will be involved with every step of the process.

Phase 1 Consultation & Quote

Every custom design and jewelry restyling begins with a conversation. During the consultation process, you will share your ideas and expectations with our jewelry designers. You will receive a complimentary quote based on the design, metal, and gemstones of your choice.

Jewelry Custom Design: CAD Design and Drawings

Phase 2 Drawings & CAD

Our in-house design studio will work with you to create an initial design concept. We either create a sketch on paper or generate the design using a CAD program (computer aided jewelry design). These CAD drawings are multi-angled renderings of your piece.  Designs can be modified during this process based on your feedback.

Phase 3 Wax Models

Once the design has been approved we create a wax model via our 3D printer.  In some cases, the model is created by hand cutting the wax.  These wax models will be presented to you to approve or request modifications before the process moves forward.  You will be able to see the design and have an understanding of how the finished product will look.

Phase 4 Approval & Casting

Once the wax model is approved by you, it is now set for casting – a process in which the wax model is placed inside plaster, melted out of the mold to form a cavity and molten metal of your choice is poured into to create your piece.

Phase 5 Finish & Detailing

Diamonds or gemstones will be set during this step. Your crafted piece is then polished resulting in a beautifully finished creation. Before delivering to you, your custom designed jewelry is thoroughly inspected by our Quality Control Department. We make sure the design is well executed and is as perfect as it can be.

Depending on the design, your personal creation normally takes anywhere from 2 to 4 weeks from consultation to completion. However, we can always accomdate rush orders and work with your schedule to make it convenient for you.
