What is the state gemstone of Arizona?

The state gemstone of Arizona is turquoise. Arizona has a long history of turquoise mining and is one of the leading producers of this precious stone. The vibrant blue-green gemstone has been used for thousands of years, both for jewelry and as a cultural symbol among Native American tribes in the region. Arizona’s copper-rich soil and dry climate are ideal for the formation of turquoise deposits, particularly in the southwestern parts of the state. The gemstone was officially designated as the state gemstone in 1974, reflecting its cultural and economic significance.
