Our Custom Design Process

Designing a custom piece means you get to design your own jewelry to your exact taste and add personal details. For engagement rings, you can design one from scratch using a new diamond or we can design around an heirloom diamond that has been passed down through generations. Looking for something new to celebrate one of life's many milestones or just looking for something to celebrate YOU, we can redesign one of your current pieces or start from scratch to create your vision.


At VAS Bijoux, we offer a service and create a luxury experience, customized just for you. You will work one-on-one with Vittoria who, as a visionary, artist, engineer, and gemologist, can bring your vision to life. All of this can be done virtually, from the comfort of your own home, or by appointment only in our downtown San Francisco studio.

 "Vittoria is a masterful artist, designer, and jeweler. The meticulous detail she puts into every piece is astounding. She is probably the best custom fine jewelry designer I've encountered in my 15 years in this business. Trustworthy, personable, and honest, she's definitely the one who you want handling your fine jewels."

- Jacqueline S.




 We offer a 30-minute complimentary design consultation. This consultation is one-on-one with Vittoria to discuss the idea you had in mind for your custom piece of jewelry. The consultation can be held by phone or video chat.

Gemstone Selection

We will help you select your center diamond or gemstone through our vast network of suppliers. The diamonds we source are all GIA certified and can either be newbies to the diamond pipeline or post-consumer recycled estate diamonds. The colored gemstones are sourced from a vast network of suppliers all of whom are vetted to ensure that we only work with vendors adhering to sustainable practices and when possible, sourcing directly from artisanal miners. We are also more than happy to work with your heirloom diamonds or gems.

Design Your Jewelry

You will receive a hand-rendered, realistic sketch of the proposed piece. The drawings are detailed, realistic and show multiple views of the jewelry so there are no surprises when we move into the fabrications stage.

3D Printed Model

Prior to moving into the final fabrication stage, you are provided with a 3D printed model of your piece printed in a durable material which allows you to have a realistic understanding of what your piece will look like. This can be shipped to you directly to be tried on in the comfort of your own home. We can discuss any changes that need to be made over a video call. Once the model has been approved we will begin the final fabrication of the designs. 3D models are usually only provided for ring designs unless it is deemed necessary for other types of jewelry.
