Fine polished double-sided blank butterfly tail plate

Jiaye resurrects Victorian craftsmanship through precision jewelry findings - double-sided butterfly tail plates engineered for vintage jewelry replication and duping jewelry excellence. Forged from museum-grade 304L stainless steel, these reversible blanks feature electrochemical mirror polishing  on both surfaces - enabling artisans to etch authentic scrollwork/ivy patterns perfect for vintage jewelry restorations. The patent-pending interlocking clasp mechanism replicates 19th-century friction-fit security while incorporating modern hypoallergenic safety .

For duping jewelry specialists, these jewelry findings solve key frustrations:
✓ Reversible Authenticity: Dual 0.08Ra sides accept period-accurate engraving
✓ Duping Security: Internal spring tension matches 1890s patent blueprints 
✓ Tarnish Resistance: Titanium PVD barrier prevents patina corruption during aging treatments
✓ Production Efficiency: Magnetic alignment grooves accelerate assembly by 40%

Unlike single-sided vintage jewelry findings, Jiaye's blanks maintain waterproof integrity through laser-sealed seams - crucial for duping maritime-era heirlooms. Each plate includes a certificate of metallurgical authenticity matching 1880-1920 alloys.
