From the Anna5 Core Series
​Grounded contrast, bound in gold.
​The Onyx Cross is an exploration of deep tonal contrast, geometric symmetry, and liquid shine. This design anchors the neckline with a prominent, stylized cross motif featuring a rich, deep black stone inlay. The iconic silhouette is framed by an intricate, raised border of high-polish gold beading that captures a vintage, architectural heirloom aesthetic. The focal piece is seamlessly integrated into our signature flat snake chain, allowing a continuous, mirror-like reflection to encircle the collarbone.
​The Onyx Cross: A historic silhouette, sharpened for the modern wardrobe.
​This is a piece for the deliberate minimalist. It strips away the delicate to lean into bold, graphic lines and sophisticated, high-contrast textures. Designed to rest flush against the skin, its fluid snake chain construction allows it to drape like a liquid metallic ribbon. It commands a powerful standalone presence when framing a sharp, open-collar black blazer or layers effortlessly into an understated evening edit.
​The Anatomy of the Piece
​Engineering: Precision-forged from 316L Surgical-Grade Stainless Steel. Renowned for its exceptional strength and biocompatibility, this is the industry gold standard for long-term, irritation-free wear.
​The Finish: Our signature Molecular Fusion gold-bonding process. Unlike traditional surface plating, our gold is bonded at a structural level to the 316L core, creating a finish that is remarkably tarnish-resistant and fade-proof.
​Architecture: Integrated flat-weave premium snake chain featuring a fixed central cross medallion with a deep black stone inlay and a beaded perimeter frame.
​Durability: Naturally hypoallergenic, sweat-proof, and designed to withstand the humidity of daily life without compromising its structural integrity.
​Design Detail: Features an engineered lobster clasp with a flexible extender chain and a stamped "S.STEEL" signature tag for easy, adjustable sizing.
​The Anna5 Standard
​Most jewelry relies on surface-level plating that fades with time. We reject that standard. By bonding precious materials at a molecular level to a 316L steel core, we create jewelry that is built to stay, not just shine.
