This souvenir market just across the Alameda from the base of Cerro Santa Lucía has some indigenous and locally made crafts, including some (not the finest quality) lapis lazuli items. Get your ears or navel pierced as well. It's open daily 10–7. As in all crowded and touristy areas, keep an eye on valuables.
