Handmade in London ✦ Small-batch jewellery with soul

✨Details

Handmade in London, the Mamba Necklace is a powerful expression of contrast and emotion. This striking piece combines the grounding energy of natural black obsidian stones β€” sourced from Argentina and cut in assorted organic shapes β€” with the warmth and shine of a high-relief heart pendant in 18K gold-plated stainless steel.

At approximately 3 cm in length, the central pendant adds a sculptural focal point that evokes both boldness and romantic intensity. With a total length of around 50 cm, the necklace sits gracefully along the collarbone, making it ideal for statement wear, whether layered over a crisp shirt or styled with evening silhouettes.

This artisan jewellery piece is designed in small batches and hand-strung in our London studio, reflecting Lucy Andy’s dedication to craftsmanship, individuality, and timeless appeal. The Mamba Necklace is more than an accessory β€” it’s a story of texture, contrast, and emotion, wrapped in raw elegance.
