Clearly the main business of this museum is to sell amber, but they do have a nice exhibit of different kinds of amber. I can now assure you that there are probably more types than you ever expected. Our Vilnius resident tour guide directed us to this establishment. We learned about every possible test to determine if a product was pure amber. If your main interest is just to learn more about amber you can do so without any pressure to buy. If you want to buy they have a wide range of items for purchase. My wife purchased two pairs of earrings for relatives. Our trip took us north through Lithuania, Latvia, Estonia, and St. Petersburg. A general shopping tip -- my wife did buy one other amber item -- she said if she had known the prices were noticeably higher as we went north she would have purchased more at the amber museum.
