Black Onyx + Moonstone Heart Necklace
One-of-a-Kind Statement Necklace | Handmade in the USA
Subtle, striking, and deeply expressive—this heart necklace is a study in contrast, balance, and intention. At its center is a one-of-a-kind heart-shaped composite stone, handcrafted in the USA from genuine black onyx, soft calcite, and warm bronze. The palette is calm yet powerful, grounded by inky black and lightened with natural movement and depth.
The heart is elegantly bezel-set in sterling silver and accented with a sculptural sterling and bronze “cloud” detail, adding an artful, symbolic touch. A 4mm round moonstone, also hand bezel-set in silver, floats gently alongside—offering a quiet glow and a sense of balance and calm.
Finished with a sterling silver chain, this necklace feels modern, intentional, and effortlessly wearable. It’s a statement piece for the woman who loves meaning in her jewelry—where design, materials, and craftsmanship come together as one.
Handmade with care in our Sewickley, Pennsylvania studio, this necklace is truly one of a kind.
