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).
