Every piece is made to order, what does that mean?

Every piece in the collection is made specifically for you when you order. Please allow 6 to 8 weeks before it reaches you. If you need a piece by a specific date, get in touch at s@stephanievanzwam.com. Stephanie will always do her best to accommodate.

Can I customise an existing design?

Most pieces in the collection can be personalised: gold colour, diamond size, stone shape, the details that matter to you. Get in touch and Stephanie will let you know what's possible for the piece you have in mind.

Can I have something engraved?

Engraving is available on select pieces: a name, a date, or a message known only to the person who wears it. Get in touch to discuss what is possible for your piece.

How long does a bespoke commission take?

The design phase moves at your pace, refined until it feels entirely right. Once you are happy with the design, production takes six to eight weeks depending on the complexity of the piece.

Can I bring my own stone?

Yes. Working with a stone that already belongs to you, whether inherited or simply loved, is something Stephanie approaches with great care. The history it carries becomes part of the design. Bring it to the consultation and she will advise on the best way to work with it.

With a free, no-obligation consultation, in person in Nyon, by video call, by phone or by email. Send your enquiry from the Bespoke page and we'll arrange it together.

How does the deposit work?

Once you approve the final design, a deposit confirms your commission. The deposit becomes non-refundable once you approve the final design and pay it, because we buy your stones and materials specifically for your piece.

Are your diamonds certified?

Every diamond comes with its own independent certificate from the GIA or IGI, confirming exactly what the stone is. Small accent stones are not individually certified.

Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds are physically, chemically and optically identical to mined stones. The difference is origin. They are grown from a diamond seed under precisely recreated conditions rather than formed in the earth over millions of years.

How do I find my ring size?

A complimentary ring sizer is available on request. Rings are available in EU, UK and US sizes, including half sizes. If you are between sizes, Stephanie will advise on the best fit for the style you have chosen. One complimentary resize is included with every ring, one size up or down.

Is resizing available?

Resizing is available for all Stephanie Van Zwam pieces and takes approximately two weeks. The cost varies depending on the complexity of the ring. Get in touch to discuss.

What payment methods do you accept?

Payment is accepted by credit and debit card, PayPal, and bank transfer. All transactions are processed securely through Shopify Payments.

Do you work with international clients?

Yes. Stephanie works with clients across Switzerland and internationally. Consultations are available by Zoom, phone, or email, and the full process can be completed from anywhere. All pieces ship worldwide.

How will my piece arrive?

Engagement rings arrive in a lacquered wooden box, the kind you keep. All other pieces come in a branded card box. Shipping is free wherever we deliver, always insured with DHL Express.

Can I return my piece?

Every piece is made to order for you, so we cannot accept returns if you change your mind. If you change your mind just after ordering, write to us straight away: if we haven't started your piece, we cancel and refund you in full. Faulty pieces are covered for 2 years, and every ring includes one free resize. Full details are in our Returns policy.

What if my piece arrives with a fault?

If a piece arrives with a fault, please get in touch at s@stephanievanzwam.com within two years of receiving it. Faulty pieces will be repaired, exchanged, or refunded. Each situation is assessed individually and handled with care.

How do you use my personal data?
