If you got tricked into thinking these beautiful blue gemstones were sapphires, then let us tell you - that's a common fallacy. Benitoite is a bright blue crystal discovered by James M Couch in 1907.
It was mistakenly thought to be blue sapphire due to the similarity in color. This stone derives its color due to the presence of barium titanium cyclosilicate, which forms in low temperature and high-pressure areas such as convergent plate boundaries that are commonly found in the oceanic crust of the earth. Benitoite is known as the state gem of California as it was originally found in San Benito river, California. The best quality Benitoites are found here, just as for these ones that we have featured today.
