A play of contrasts, natural diamonds encircle a deep black onyx gemstone, framing light against shadow and giving the piece a striking, refined vintage charm.
Crafted in 18k gold, this necklace carries an effortless elegance. Styled simply, it becomes quietly powerful with a tailored suit and gracefully understated with a black dress. Feminine yet enduring.
It’s made to be loved for a lifetime, a modern heirloom meant to be passed down.

- When your jewellery is not being worn, keep them in a jewellery box or a soft pouch to prevent scratches and tangles.
- Avoid contact with harsh chemicals like bleach and chlorine, as they can be damaging to your jewellery.
- Take off your jewellery before exercising, going to beach, pool or any activity that could potentially scratch or dent it.
