Shop Lab Grown Diamond Necklace

A diamond necklace is more than just an accessory—it’s a symbol of elegance, strength, and personal style. Our collection of lab-grown diamond necklaces is thoughtfully designed to offer beauty with a conscience. Whether it’s a solitaire pendant that captures the essence of simplicity, a classic tennis necklace that commands attention, or a dainty bezel-set chain that layers effortlessly, you’ll find something for every mood and moment.

We craft each piece using 100% solid 14K & 18K gold, available in white, yellow, or rose finishes. The diamonds are lab-grown, created through advanced technology that replicates the natural growth process. They are chemically and optically identical to mined diamonds, offering the same sparkle, durability, and timeless appeal without the environmental harm or ethical concerns.

Each necklace features IGI-certified diamonds, hand-selected for brilliance and set with care by our skilled artisans. From everyday essentials to occasion-worthy pieces, our necklaces are perfect for gifting—or treating yourself to something meaningful.

Lab-grown diamond necklaces have become increasingly popular in the UK for their ethical sourcing and approachable luxury. They offer a sustainable way to shine, aligning with modern values while honouring timeless style.

When you shop with The Karat Store, you’re choosing handcrafted excellence, verified quality, and jewellery that’s made to be worn, loved, and passed on.
