Here we’re sharing the answers to some of our most frequently asked questions. Please do feel free to get in touch with any other questions. Thank you!


Where are you based?

Our office is located in Hatton Garden, London, UK. 

Do you have a shop I can visit?

Currently we are an online retailer only, however we do take in-person appointments in London. Please contact us to enquire. 

Is it possible to try the rings on?

If you're in the London area, it is possible to make an in-person appointment. Otherwise, we recommend ordering a ring sizer if you’re unsure of the size you require. The cost of the ring sizer is redeemable against any purchase. We can also provide any additional photos, videos or details about any item if you’re unsure before ordering. (Please just send us an email to enquire.) If you order a ring and it doesn’t satisfy you in any way, we also offer a full Refund Policy; please read for further details.

Can you size the ring I order?

Yes! We are able to size almost any of our items, free of charge, not including our Sterling Silver collection. Please note your size in the Notes section upon ordering and allow up to two extra weeks for delivery if sizing is required. If you’re unsure of your size, we welcome you to order our ring sizer in advance, especially when ordering one of our custom eternity bands. 

Do you ship internationally?

Yes! We offer free tracked and insured delivery within the UK, and fast tracked and insured internationally. Please see all details regarding our fully tracked and insured shipping practices here. Please also note that all local import charges and taxes are the responsibility of the buyer. 

Is there someone I can talk to?

Of course! Katherine and the team are always delighted to speak more about the jewellery and advise you on any further details. Please see our other contact details here.

May I pay over the phone?

Yes! Please contact us at 0800 878 6789, or we welcome you to email us to arrange a time to pay over the phone which will suit you best.

What can I do if I order something and it doesn’t suit me?

Don’t worry. We want you to fall in love with every item in your jewellery collection and welcome you to return or exchange it, if not. Please see all the details of our Refund Policy here.
