Textural, powerful, and unmistakably modern, the John Hardy LoveStruck Heishi Pendant Necklace [NBP4303831BONLGD] redefines statement diamond jewellery through contrast—pairing a commanding 3.00 carat lab-grown diamond with the grounded intensity of natural black onyx.

This is not a traditional diamond pendant.
It is a composition of material, scale, and attitude.

At its centre, a freeform oval brilliant diamond is bezel-set in sterling silver—framing the stone in a clean, sculptural silhouette that emphasizes both its size and brilliance. The bezel setting enhances durability while reinforcing a contemporary aesthetic, allowing the diamond’s fire and presence to take full focus. 

With G colour and VS clarity, the diamond delivers exceptional brightness and refinement—ensuring that its substantial carat weight is matched by high optical performance. 

What sets this piece apart is the heishi bead construction, combining treated black onyx and hand-crafted sterling silver elements to create a rhythmic, tactile chain. The result is a striking interplay between matte and polished surfaces, light and shadow, refinement and edge.

The pendant itself measures approximately 13.3 × 12.3 mm, offering strong visual presence, while the 4MM gauge bead chain reinforces its bold, grounded aesthetic. 

The outcome is unmistakable: a necklace that blends the scale of high-carat diamond jewellery with the attitude of modern design.
