Castafiore is the reference platform for luxury vintage jewelry, where serious collectors, independent resellers, and discerning buyers come together around pieces that carry history. In a market long dominated by auction houses and opaque pricing, Castafiore brings curation, transparency, and digital reach to heritage jewellery. Q1 2026 was its best quarter ever, recording €1M in GMV, up 50% year-on-year, with an average order value of €2,985 and pieces above €5,000 representing 56% of sales. With 795,000 unique visitors, 38% international GMV, and Printemps Haussmann discussions underway for an end-2026 boutique opening, Castafiore is building the global home for fine vintage jewellery.
