The name to know is DRAGHI. And bring American dollars! Located about 1.5 hours outside the city center of Buenos Aires in a charming town called San Antonio de Areco, Draghi preserves the traditions of Argentine silverwork. The town itself reminded me of a smaller, South American Santa Fe for its town square and all the art galleries & shops. The building is part museum where you're able to browse a priceless collection of items from the 19th century including knives, belts, and jewelry. You can also watch the artisans at work. The shop was my favorite part and a group of us browsed rugs, blankets, necklaces, and rings.
I spotted the ring I wanted and discovered it would be $120 on my credit card, but $50 if I paid American cash. Why? American dollars have a high black market value and are highly coveted by Argentines so BRING more dollars than you think you'll need. This article explains it well - apparently President Cristina (whom every single person I talked to HATED) has put some insane limits on foreign exchange, and the peso is the world's worst performing currency. I don't completely understand, but know I got my ring for a great deal!
