An absolute investment-grade fine estate jewelry masterpiece for the serious luxury collector! This listing is for a breathtaking pair of true-vintage 15-year-old solid 18K white gold jumping dolphin leverback drop earrings. Masterfully handcrafted in Italy around 2011, the front bodies are heavily encrusted in a seamless, brilliant field of micro pavé-set white diamonds that catch the light with incredible prism fire. Each dolphin is detailed with a vibrant, bezel-set natural blue sapphire eye. The reverse showcases an exquisite open-work structural honeycomb under-gallery lattice backing common only to high-end luxury boutique jewelry houses. Fully hallmarked and authenticated on the inner post rails with: “18K" “750" (Solid 18-Karat Gold purity) Official Italian registration oval mark "★ 3082 AL" (proving boutique Alessandria, Italy manufacture). Condition: Pristine vintage estate condition! Never worn, but stored out of its original retail box for 15 years, so the metal may show ultra-light micro-handling scuffs upon close inspection from storage. Entirely clean, 100% complete gemstones with zero missing pieces, and perfectly firm, snappy leverback latches. An incredible, high-value 18K gold heirloom piece. From a clean, smoke-free home. Will be packed with extreme, white-glove protective padding and shipped securely with full signature tracking and insurance!
