Why you'll love it
You pay for the piece, not the markup
Buying direct from the trade means the same stone and the same craft without the high-street markup.
Matched along the line
Each diamond is chosen to the same colour and clarity grade, so the necklace catches the light evenly rather than in patches.

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 10 days.
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.
Are the diamonds matched along the necklace?
Each diamond is selected to the same colour and clarity grade, so the necklace catches the light evenly rather than in patches. Independent GIA or IGI reports are listed on the necklaces that carry them.
How wide is the necklace collection?
Tennis necklaces and lines across carat weights and metals, held in the workshop. Close but not quite is a conversation, not a dead end.
Can I change the chain length?
Yes — tell us the length you want when you order and we will make it to that measurement. If you are unsure, message us and we will talk you through where each length sits.
