This genuine Marquise Black Onyx Necklace, available in 18k gold plated sterling silver or 925 sterling silver, features a hand-cut, moon-charged onyx crystal known for its powerful protection, grounding and inner strength. Designed by Jewel Sisters, it blends sleek, modern style with meaningful crystal intention.

Black onyx carries a deep, steadying vibration, helping you stay centred and confident throughout busy days. The marquise-cut gemstone creates a bold, elongated silhouette, while your metal choice offers either a warm gold finish or a cool, timeless silver shine.

Perfect for everyday wear, this necklace supports energetic boundaries, focus and resilience from the moment you put it on.
