Advice

Questions, answered

A few things couples usually ask before they visit Hatton Garden.

What makes Primo different from other jewellers?

Every Primo ring is designed and crafted in our Hatton Garden workshop with one-to-one gemmologist guidance. We combine traditional craftsmanship with certified lab-grown and natural diamonds, transparent pricing, and a calm, unhurried consultation experience.

Do you make engagement rings in-house?

Yes. Our goldsmiths, setters and designers work together under one roof in Hatton Garden. Each ring is made to order, which means tighter quality control and a piece that is truly made for you.

Can I visit your showroom or book a virtual appointment?

Absolutely. Book a private consultation at our Hatton Garden showroom to explore designs in person, try on settings and discuss bespoke options. We also offer virtual appointments if you cannot visit London.

Can I attend my engagement ring consultation with my partner?

Of course. Many couples visit together, and we also welcome private appointments if you prefer to choose a ring as a surprise. Our gemmologists adapt the consultation to whatever suits you best.

Where are you located?

Our showroom is at The Record Hall, 16-16A Baldwin's Gardens, London EC1N 7RJ — in the heart of London's jewellery quarter. We are a short walk from Chancery Lane and Farringdon stations.

How long does it take for a custom engagement ring to be made?

Most bespoke engagement rings are completed within 4–6 weeks from design approval, depending on the complexity of the setting and diamond sourcing. We will give you a clear timeline during your consultation.

Do you offer lab-grown diamonds for engagement rings?

Yes. We offer certified lab-grown and natural diamonds, each accompanied by a GIA or IGI report. Our gemmologists explain the differences in value, appearance and sustainability so you can choose with confidence.
