This pint-size 200-square-foot Upper West Side boutique marks Gas Bijoux's second New York store. The Bijoux family has been hand-making its fashionable accessories for 40 years at their atelier in Marseille, France. Each piece is assembled, polished and enameled by hand by their own master craftsmen. Producing only limited series and unique pieces ensure you won't be seen with the same jewels as every one else. The shop stocks its signature gold-plated filigreed chandelier earrings ($165), silver-plated cobra bangles ($235), silver heart necklaces ($135) and charm bracelets in every color (from $55).
