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.
Amazonite Natural Birthstone. Amazonite which is turquoise in color is one of the natural birthstones of those born as spring begins (20 March to 19 April). Turquoise crystals bring you discovery and balance. Their vibrations help you find yourself and return to equilibrium.
