moonstone

Moonstone is the birthstone of June. It is a gemstone with an impressive appearance, exhibiting the "Schiller effect" in which the light stands out. In addition to white, it comes in various colors such as orange, green, and black. "Blue Moonstone", which indicates blue Syrah, was once produced in Sri Lanka, but now it is rarely produced and rarely appears on the market. Therefore, minerals that belong to the same Feldspar group, such as peristerite, labradorite, andesine labradorite, are commonly sold as "Blue Moonstone."
