alexandrite

Alexandrite is known as one of the birthstones for June. Its main feature is its color-change effect, which means that its color changes depending on the light source. It was once mined in large quantities in Russia, but today its main production area is said to be Brazil. Since it is difficult to find large stones, the larger they are and the more obvious their color-change effect is, the more valuable they are.
