Questions customers ask

Are your diamonds certified?

Yes. Every diamond we sell is IGI or GIA certified, and every piece over 1 carat comes with its own IGI or GIA certificate.

Can you make a design for me?

Yes. Many of our pieces are made to order, and our Bespoke service can help you create a piece of your own. Write to info@johngems.com with your idea.

How long does delivery take?

Many of our pieces are made to order, so orders are usually prepared within 15–30 business days. After dispatch, UK orders usually arrive in 3–7 business days and international orders in 7–10 business days.

Can I return my order?

Yes. You can cancel an eligible online order within 14 days from the day after you receive it, in line with UK consumer law. The piece must be unworn, with all tags and certificates. Write to info@johngems.com to arrange the return.
