What is the true birthstone for June?

The traditional birthstone for June is the pearl. However, in 1912, the American National Association of Jewelers created a modern birthstone list, which includes three options for June: pearl, alexandrite, and moonstone. Alexandrite is a relatively rare gemstone that changes color depending on the lighting conditions, while moonstone has a unique sheen and is typically pale blue or gray with a hint of rainbow-like colors.
