The showroom

In the heart of Mayfair

A few steps from Bond Street’s galleries, the Celviarn showroom is a quiet room for a loud decision — a place to compare stones in natural light, try pieces on at leisure and talk through a commission with someone who makes jewellery for a living.

London Showroom FAQs

How do appointments work?

Choose a time that suits you and a specialist will prepare a private viewing based on what you’re looking for. Appointments typically last forty-five minutes to an hour, with no obligation to purchase.

Do I need an appointment to visit?

No — walk-ins are welcome during opening hours. On weekends we recommend booking ahead so a specialist is free the moment you arrive.

Which pieces can I try on?

The full current collection is available to try on, alongside a rotating selection of one-of-a-kind stones. Tell us ahead of your visit if there is something particular you’d like set aside.

Can you redesign a piece I already own?

Yes. Our workshop regularly resets heirloom stones into new settings. Bring the piece to your appointment and a designer will talk through the possibilities with you.

Is there parking nearby?

There is metered street parking on the surrounding streets, and several public car parks within a five-minute walk of the showroom.

How many people can I bring?

Appointments are intimate by design, but you are welcome to bring up to three guests — many engagement appointments include a partner, parent or close friend.
