Why you'll love it
You pay for the stone, not the chain
Buying direct from the trade means the same stone and the same craft without the high-street markup.
Independently graded
Certified stones arrive with their IGI report, so the colour, clarity and carat are verified by the lab rather than by us.
What our clients say
Real customers, verified on Judge.me and eBay — read what arrived for them before you decide.

FAQ
Frequently asked questions
Here are answers to some of the most common questions. If you can't find what you're looking for, our client care team is always here to help.
Where is this made?
Designed in Hatton Garden and set by hand in our own workshop, then finished and hallmarked by the Assay Office London before it ships — British made, not imported jewellery with a London stamp added later.
Why is Amada less than the high street?
We cut out the wholesale chain. You buy from the workshop that makes it, so the money goes on the diamond and the setting rather than a succession of markups. That is how we put a better stone in front of you for the same budget.
Can I return it?
Yes — 30 days from delivery, unworn and undamaged, in its original packaging. Email sales@amadadiamonds.com and we will confirm the return, then send it back insured and signed-for or drop it into our Hatton Garden showroom. Made-to-order, engraved and already-resized pieces cannot be returned.
Is delivery insured?
Every order ships fully insured and needs a signature. If anything happens between Hatton Garden and your door, it is our problem, not yours. Certified pieces arrive with their report, which most insurers accept for cover; ask us if you need a separate written valuation.
How long will my order take?
Ready-to-ship pieces dispatch within 1–3 working days. Made-to-order is finished in Hatton Garden in about 2–3 weeks.
Can I see it before I buy?
Yes. Book a short appointment at Hatton Garden — bring a photo, a budget, or nothing at all. No pressure to buy on the day.
Will it come with a certificate?
Yes. This listing is independently certified — GIA for natural diamonds, IGI for lab-grown where the piece carries one. Colour, clarity and carat are verified by the lab, not by us, and the matching report ships with the piece.
How many engagement rings do you actually hold?
Thousands of settings and certified stones, from solitaires to hidden halos, in the workshop rather than on a render. If the one on this page is close but not quite, we will find the one that is.
How do I find her ring size without asking?
Borrow a ring she already wears on that finger and message us the inside measurement, or visit our Hatton Garden showroom for a complimentary finger measurement. If it is still not right, the first resize is complimentary.
What if I get the ring size wrong?
The first resize is complimentary. Send it back within 30 days and we will adjust it for you.
Book appointment
See this piece before you commit to it.
