Bvlgari BV Classic Spring Necklace

A timeless and versatile classic design, this exceptional piece features an exclusive reverse-engineered spring structure unavailable anywhere else online. It is the only true-to-original version on the market—no compromises. Constructed with double vacuum technology and five-layer thickened real gold plating, it boasts a proprietary reverse spring mechanism and deeply engraved original logo imprint. The lobster clasp features authentic corrosion-treated curvature matching the original, along with a three-loop extension chain just like the official retail version. Measuring 40 + 3 + 3 cm, it adheres precisely to standard boutique dimensions. Still purchasing those off-spec, bulky, oversized imitations flooding the market? [Smirk][Smirk] Customers unfamiliar with authenticity are encouraged to compare at official boutiques before buying. Once our product launches, it instantly outshines everything online—so superior that it sells out within minutes without extensive promotion.
