Finest4Cs FAQ’s
How does the bespoke process work?
Every piece we create begins with a private consultation at our Hatton Garden showroom. During your appointment, our diamond experts will guide you through diamond selection, ring design, metal choice and setting style. Once your design is confirmed, our master craftsmen create your piece to order. We keep you informed at every stage.
How do I book a consultation?
Simply book online via our Book a Consultation page , send us a WhatsApp message, or email us at info@finest4cs.com. Consultations are available at our showroom at Unit G.1, Treasure House, 19-21 Hatton Garden, London EC1N 8BA. We offer both weekday and weekend appointments.
How long does a bespoke piece take to create?
Most bespoke engagement rings are ready within 2–4 weeks of your design being confirmed. We will give you a precise timeline at your consultation. If you have a specific deadline — a proposal date, anniversary or birthday — let us know and we will do everything we can to accommodate it.
Do you offer both natural and lab-grown diamonds?
Yes. We offer a curated selection of both natural and lab-grown diamonds, all certified by GIA or IGI. Both are chemically, physically and optically identical — the difference is origin and price. Lab-grown diamonds typically cost 60–80% less than natural diamonds of equivalent quality. We are happy to walk you through both options at your consultation.
Where are you located?
Our showroom is at Unit G.1, Ground Floor, Treasure House, 19-21 Hatton Garden, London EC1N 8BA — in the heart of London's jewellery quarter. We are open Monday to Friday 10am–6pm and Saturday 10:30am–5:30pm. The nearest tube stations are Chancery Lane (Central line) and Farringdon (Elizabeth, Circle and Metropolitan lines).
