Benitoite is the state gem of California due to its unique and striking blue color, as well as its rarity; it is found almost exclusively in San Benito County. Discovered in 1907, it was designated the state gem in 1985, symbolizing California's geological diversity. Its distinct characteristics, including its high birefringence and fluorescence under ultraviolet light, further contribute to its significance and appeal.
Benitoite is a rare mineral found only in California. It is typically blue in color and is sometimes referred to as the "California State Gemstone."
