Benitoite Crystals
Benitoite crystals are only found in California near the San Benito River. A local mineral prospector was looking for mercury and copper and came across this rare blue crystal. He thought he found a Sapphire but the University of California determined they had found a new mineral
Since Benitoite is only found in California, it’s very rare and therefore quite valuable. Due to its high brilliance and dispersion, Benitoite is very popular among collectors.
Mine production is on the low to nonexistent side which means the value of these crystals continues to increase in price.
Crystals over one carat are very rare and the largest one ever found was 9 carats.
