State Gemstone

Blue chalcedony, commonly called the blue agate, was named the state gemstone by legislative action in 1967. A pale stone, the blue agate sometimes has a dark internal form with bands of blue and white and often has a colorless streak. Blue agates are used to make jewelry. The blue agate can be found in northwestern Nebraska, where it formed in wind-blown silt and claystone.
