A standard list of acceptable birthstones is used today, but those gemstones were arbitrarily selected many years ago. People originally chose which gemstone to wear based on its color and the magical or healing powers associated with that color. You have the choice of selecting a birthstones for the day you were born, the birth time, the birth month, zodiac sign as well as by the color if you choose a synthetic stone.

Humanity is beginning to rediscover the almost forgotten healing arts based on earth energies that is thought to be inherent in several different stones. Crystals and minerals were the first thought to contain the necessary power used in healing many types of sickness. Next came the gemstones themselves and the clearer and more perfect, the more power they contained.
