Colorado State Symbols - State Gemstone Aquamarine

If you watch Prospectors on the Weather Channel, you know that Colorado's state gemstone is aquamarine.  The largest aquamarine crystal ever found in North America was found on Mt. Antero by Steve Brancato.  It's now is the Denver Museum of Nature & Science. This photo of the crystal is from the Denver Post by C. Walker.
