Loose stones and strings of faceted spinels, aquamarines, citrines, amethysts, rubies, emeralds, smoky and lemon topaz, peridots, pink and green tourmalines, and sapphires—all can be custom-crafted into one-of-a-kind necklaces, rings, bracelets, or pins in a few hours at Jaipur's legendary Gem Palace, presided over by jeweler Sanjay Kasliwal. It's an essential stop for travelers in search of the finest antique and modern jewelry. One highlight: a 22-karat gold bracelet by Parisian designer Marie-Hélène de Taillac that sparkles with rose-cut diamonds "floating" along its gold filaments ($8,000). M. I.
