Double Layer Tennis & Box Chain Necklace

Exuding a high-fashion, layered aesthetic with a sophisticated contemporary edge, this premium double-strand chain necklace set is masterfully engineered to target the high-demand layered and multi-chain segments within the European and North American B2B fashion jewelry markets. Referencing the detailed specifications provided in the technical schematic, the avant-garde design showcases a beautifully pre-layered combination of two distinct, complementary chains that create a perfect dimensional harmony. The inner strand features a glittering, classic tennis-style chain precisely micro-paved with a continuous row of custom-cut clear zircon stones measuring a delicate 1.6mm in thickness width, while the outer strand presents a modern box chain punctuated with evenly spaced, polished gold satellite beads measuring 2.9mm in width.

The meticulously proportioned lengths are optimized to ensure a flawless drape along the neckline without tangling, with the inner tennis chain measuring a base length of 45cm plus a 5cm extender and the outer satellite chain measuring a base length of 47cm plus a matching 5cm extender. Masterfully forged from genuine medical-grade 316L stainless steel, this pre-layered necklace delivers exceptional structural solidness, guaranteeing that each component remains entirely anti-deformation, rust-proof, and highly scratch-resistant compared to traditional brass or softer precious silver alternatives. Utilizing state-of-the-art physical vapor deposition vacuum PVD 18K gold plating technology, the opulent golden mirror-polish finish is molecularly bonded to the steel base to guarantee a tarnish-free, waterproof, and fade-resistant longevity that withstands daily cosmetics, sweat, and perfume without leaving green residue or causing skin discoloration. Weighing a perfectly balanced 5.6 grams, the set provides a premium, substantial texture and high-perceived retail value on display while remaining completely comfortable and lightweight for extended day-to-night wear.

Built in absolute compliance with strict Western consumer health and environmental safety protocols, this entire hypoallergenic necklace is 100% lead-free, nickel-free, and cadmium-free, meeting all stringent European Union REACH regulations and United States California Proposition 65 consumer protection standards for sensitive skin types.
