Tennis Lab-Grown Diamond Necklace

Our lab-grown diamond tennis necklace is finished with a streamlined box clasp, designed for secure yet effortless everyday wear. The spring-tensioned tab clicks seamlessly into the box closure, making it easy to fasten and remove without compromising security.

The single-clasp design keeps the continuous line of diamonds uninterrupted, clean, elegant, intentional.

For an additional cost, we can add a dual safety box clasp for enhanced security. Note that dual clasps are more difficult to remove and not our recommendation, so consider your preference based on how you'll wear the piece.

Yes, we offer a complimentary sizing adjustment within the first 12 months after purchase. The standard length of this diamond tennis necklace is 45cm, which typically sits at the collarbone. For any substantial customisation queries, such as a significant change to the length, please make an appointment with us to discuss a bespoke piece.

Yes, while elegant and luxurious, our diamond tennis necklace is crafted for durability, with a safety-latch box clasp and reinforced link construction.

If you're layering it with other necklaces, wear your tennis necklace on top to prevent tangling and ensure the diamonds don't scratch your gold necklaces or softer gemstones.

Please ensure to take your necklace off when you get home each day, and before going to the gym, showering, swimming, or going to bed. When you aren't wearing your necklace, store it safely.

Our lab-grown diamond tennis necklace is available in 18k yellow and white gold. Both are luxurious and durable, it’s simply a matter of your personal preference. Yellow gold is classic and warm, contrasting beautifully with the lab-grown diamonds. White gold is timeless, cool-toned and versatile for styling alongside any other precious metals. To help you choose, consider the jewellery you usually wear, especially if you plan to layer your necklace with other pieces.

Selecting your carat weight is also key to making this piece reflect your personal style and feel perfect for you. 4.50 carat (shown in the images), offers noticeable yet wearable luxury for every day. 8.0 carat is a bolder expression, while 12.0 carat creates a glamorous statement piece. If you’d like help in selecting a tennis necklace tailored to your style, book an appointment with us in-studio or virtually.

The simplest rule for preserving your piece is to remove your fine jewellery at the end of each day, and before activities where your necklace could be knocked, snagged, scratched, or exposed to any harsh chemicals - such as going to the gym, swimming, or doing household cleaning. 

Clean your lab-grown diamond jewellery regularly with warm water and mild soap, and store your necklace safely while you’re not wearing it - ideally, keep it lying flat in a jewellery box or tray, as bunching or coiling may cause it to kink. View our full jewellery care guide here. 

Yes, our diamond tennis necklace is backed by a three-year warranty against manufacturing defects.

Each piece is accompanied by a Futurae Certificate of Authenticity, verifying the authenticity and craftsmanship of your necklace. Because diamonds in a necklace generally fall below the 0.5-carat threshold (for each diamond0, they don't qualify for individual IGI grading; our Certificate of Authenticity serves as your verification of quality.

For insurance purposes, we can arrange an external professional valuation for a small fee. If you'd like this service, please let us know when you select your necklace, and we'll coordinate this for you.

Lab-grown diamonds are optically, chemically and physically identical to mined diamonds, offering the same brilliance and durability. The difference is that they are created in a laboratory setting, rather than being mined from the Earth. At Futurae, we carefully source premium and ethical lab-grown diamonds.
