There are two birthstones for the month of June. Alexandrite was the traditional birthstone for June, but due to its scarcity and cost, pearl has become June's common birthstone. The alexandrite was named after Czar Alexander II and is one of the most desired gems. Its color changes with the lighting surrounding the stone, which is called its phenomena.
Peridot is the birthstone for August. While peridot is available in a wide range of colors from yellow-green to brown, the light green or lime green variety is the one most commonly associated with August. A symbol of strength, peridot is also said to protect the wearer from nightmares.
