Why is it valuable?

This work of art is valuable because the skill, time, and effort it takes for him to create these massive works of blown glass. They are extremely intricate and catch the eye of everyone around. Not many people can do what Chihuly does with glass because it is such a fragile and tempermental medium. I also like to create 3-dimensional art but it pales extremely in comparison to the beauty of Chihuly's work.
