Illuzion Glass Galleries is home to some of the most extravagant and expensive glass pipes in the world, including a $35,000 alien throne and a $30,000 glass pirate ship. The shop also carries worked tubes and pipes from local and nationally known artists that range from $100 all the way up to several thousand dollars. Illuzion has been working on bringing in-house pipes to the people of Denver through their glass studio in the back of the store. There are also plenty of affordable pieces here, but taking a tour through the shop is worth the visit alone.
