Birth Stones

According to old and new myths, birth stones bring good luck to the person born under its month.
Each birth stone has its own unique characteristics.
The Ayurveda astrological system notes that gems are related to the various planets and produce a balancing effect to counter specific diseases. Please take a look at the Ayurveda Healing Stones section
