Advice

Frequently asked questions

A few things couples usually ask before choosing an engagement ring at Primo Diamonds.

How long does a ring take to make?

Most engagement rings are handcrafted to order in 2–4 weeks. Ready-to-ship designs can arrive within 5 working days.

Are your diamonds certified?

Yes. Every centre stone is independently graded by GIA or IGI, and the certificate is supplied with your ring.

Can I choose lab-grown or natural diamonds?

Absolutely. We offer both — our gemmologists can talk you through the differences in value, sustainability and appearance.

Can I see rings before I buy?

Yes. Book a free appointment at our Hatton Garden showroom and we will have a selection ready for you to try on — in-store or over video call.

What if I need help choosing a size?
