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.

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.

Where do I begin with a bespoke commission?

With a conversation. The consultation is complimentary and without obligation — in person, or by Zoom, phone, or email. You can book directly on the Bespoke page at stephanievanzwam.com.

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. All other pieces come in a branded card box. Every order is packaged with care.

Can I return my piece?

As every piece is made to order, collection purchases and customised pieces cannot be returned or exchanged. For bespoke commissions, a deposit is required to begin. This covers materials sourced specifically for your piece and cannot be refunded once the commission is underway. Everything is discussed openly before any commitment is made.

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.

Manhattan Round Brilliant-cut Diamond Engagement Ring

Manhattan Round Brilliant-cut Diamond Engagement Ring

CHF 3'900

Ring size guide

Manhattan in the 1920s. Vertical ambition, geometric rigour, gold catching the light between glass and stone.

This ring takes its name and its structure from that moment. The band is triple knife-edge, three parallel ridges drawn to a fine point, precise and architectural. The lines converge toward a round brilliant-cut diamond at the centre, held as if the whole structure was built around it. Which, of course, it was.

Description Description

18k white or yellow gold. 18k rose gold on request.

Round brilliant-cut diamond from 1.00 carat, F colour or above, VS+ clarity.

All diamonds are lab-grown, GIA or IGI certified. Other carat weights are available. Get in touch to discuss the stone that's right for you — s@stephanievanzwam.com
