Advice
Frequently asked questions
A few things couples usually ask before they visit Hatton Garden.
How long does an engagement ring take to make?
Most rings are handcrafted to order in 4–6 weeks. Ready-to-ship designs can arrive within a few 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.
