Here is a place where you don't expect to see so many beautiful turquoise necklaces - The Smithsonian Museum. I was pleasantly surprised to find amazing turquoise jewelry collection at the great Smithsonian Institution. The museum's online store has unique selection of elegant turquoise necklaces, rings, bracelets and earrings in many styles and price ranges. Usually museums carry only few turquoise necklaces, so I was very excited to see such wide variety of turquoise jewelry at The Smithsonian. I definitely recommend to visit their "online store":http://www.smithsonianstore.com/home.jsp. Here are some of my favorites:
