About Boutique of Diamonds, Your Luxury Diamond Jewellery Shop

Boutique of Diamonds is a premium destination for purchasing exquisite diamond jewellery online at an unbeatable price and with unbeatable service. With over 20 years of experience in the jewellery industry, our trusted experts in Antwerp and Italy carefully hand select every piece in our collection — from red string bracelets to diamond eternity rings and more — for its style, quality and brilliance. 

We believe there’s no better way to demonstrate your eternal love than by giving our treasure-forever diamond jewellery to that special someone on an anniversary, birthday or Valentine’s Day. As picking the perfect piece takes a lot of thought and care, we take the time to understand each of our items intimately so we can help you make the right choice — even if you’re simply looking to add to your own diamond jewellery collection! 

Contact our friendly team by calling +44 7498 203128 or emailing info@boutiqueofdiamonds.co.uk, and we’ll happily offer assistance during any part of the buying process, from providing free ring sizing to offering inspiration on how to style your piece to perfection. You can even book a viewing at our showroom in Mayfair, London, for a more bespoke shopping experience. 

However, these are just a few of the reasons our customers love buying from Boutique of Diamonds. We also offer free shipping to all UK addresses, next-day delivery (Monday to Friday) if you order before 1 pm, and a hassle-free 30-day money-back guarantee if you’re not 100% happy with your purchase.

Caring for Your Diamond Jewellery

Every piece of diamond jewellery in the Boutique of Diamonds collection is meticulously crafted and designed to be cherished, so you can enjoy wearing the items you buy from us as often as possible. However, there are few things you need to do to keep your jewellery bright and brilliant for longer. 

Firstly, although gold and diamond are both highly resistant to external factors, it’s wise to take off your jewellery before showering or bathing to prevent them from coming into contact with liquids and chemicals. We also suggest these items receive a professional clean at least once a year.

How We Can Help Keep Your Diamonds Sparkling

Boutique of Diamonds not only sells the finest diamond jewellery, but we also provide an outstanding customer experience. Listed below are a few of the additional services we provide.

Free Ring Resizing

If you buy one of our diamond rings for yourself or someone special and it doesn't fit beautifully, contact us, and we'll get an expert jeweller to resize it for free to ensure maximum comfort.

Free 30-Day Returns

If there's a problem with an item you buy from us, we'll happily give you an exchange or a refund. However, you'll need to return the jewellery in its original condition with its tag still on and within 30 days of receipt. We also need you to include proof of postage from the post office with any returns, and we recommend using a tracked shipping service. Sorry, but we can't be held responsible for any lost or damaged items in the post.
