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.
The birthstone for the month of January is the garnet. Some believe garnets provide safety during travels. Februaryâs birthstone is the amethyst, which is thought to make one courageous. If your birthday is in March, your birthstone is the aquamarine. Aquamarines have been associated with certain healing powers.
