Yes, many of our necklaces feature adjustable chains, allowing you to wear them at different lengths for layering or comfort. Product descriptions list the available adjustments so you can choose the style that works best for you.
Our necklaces are crafted from high-quality, recycled precious metals including sterling silver, 18K gold vermeil, solid 18K gold, and platinum. Each product description details the metal used, so you know exactly what you’re buying.
Our chains are designed to be durable and long-lasting, made with high-quality precious metals. But like all delicate fine jewellery, they should be treated with care - avoid pulling or snagging on clothing to keep your necklace secure for years to come.
Yes, our necklaces are fitted with strong and reliable clasps, designed to hold your jewellery safely in place during daily wear. Many of our designs use spring-ring or lobster clasps, known for their durability and ease of use. When putting your piece on, always double check the clasp is securely closed, to avoid losing it.
We offer necklaces in a variety of lengths, from short, delicate chains to long pendants. Standard lengths are usually 16–18 inches, but exact measurements are listed on each product page. Adjustable chains allow for even more flexibility in length. Please reach out to our customer services (https://www.thediamondstore.co.uk/pages/contact-us) with any questions you may have about the length of the necklace you’re interested in.
Yes, we offer a selection of replacement necklace chains in sterling silver, gold, and platinum. If you need to replace or upgrade your chain, you can choose from a variety of styles and lengths to match your pendant. If you’d like to purchase a replacement chain for a pendant necklace, please get in touch with our customer services who can advise you further (https://www.thediamondstore.co.uk/pages/contact-us).
We want you to feel completely confident when you shop with us. That’s why we offer FREE 30-day returns for refunds and 60-day exchanges across the UK and Northern Ireland.
If you’ve ordered a ring smaller than a size J or larger than a size Q, don’t worry — these are custom sizes, but we’re still happy to offer a free exchange or resizing if the fit isn’t quite right.
Changed your mind? No problem — you can cancel your order anytime before it’s been dispatched.
Just reach out to our friendly team via Live Chat, by email at customerservice@thediamondstore.com, or give us a call on 0345 084 1200 (or +44 345 084 1200 if calling from outside the UK). Please have your order number handy to help us assist you as quickly as possible.
Please note that for rings smaller than size J or larger than size Q, the width may vary slightly (up to 10%) due to the crafting process. If you need any adjustments, we’re happy to help.
If your item arrives damaged or defective, we’ll make it right — fast. We’ll either repair or replace it at no cost to you, or provide a refund once it’s been assessed by our head jeweller.
Our standard returns policy is 30 days to return, and 60 days to exchange.
We stand by the quality of our jewellery. That’s why all our pieces come with a 5-year warranty against defects in materials or craftsmanship. Every item is also fully hallmarked according to UK legislation, confirming its authenticity and origin.
Once we’ve received and inspected your returned jewellery, we’ll process your refund right away and email you to confirm. Depending on your bank or payment provider, it may take 3 to 5 working days to show up on your statement.
We’ll always refund you via the same method you used to make your purchase — whether that was credit or debit card, PayPal, Pay4Later Finance, bank transfer, or another option.
To avoid delays, make sure to include the returns label print-out with your parcel. This helps us identify your return quickly.
We’re proud to say that all our diamonds are conflict-free and fully compliant with United Nations regulations. When you buy from us, you’re choosing ethical beauty.
