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.
February birthstone, amethyst Amethyst is the birthstone for February. The amethystâs purple tones range from deep, dark violet, to the less coveted pale lavender. The gemâs rich color is associated with royalty and nobility.
