The term "Navratnas" refers to a group of nine extraordinary jewels or gems, often associated with the royal courts of ancient India. In a historical context, these nine individuals were renowned for their exceptional skills and contributions in various fields, including literature, music, and administration. The most famous example is the Mughal Emperor Akbar, who had a council of nine advisors known as the Navratnas. In astrology, "Navratnas" also refers to nine precious gemstones that are believed to have specific astrological significance. Each gemstone corresponds to a planet in Hindu astrology, such as Ruby for the Sun and Emerald for Mercury. Wearing these stones is thought to bring good fortune and balance to an individual's life.
