Navratna necklace

Navratnais the Sanskrit word which means "nine gems". Jewelry in this style has been used for thousands of years in Eastern religions.
A bow and a mantra in bronze or crystal complete the nine stones
The nine gems concern astrology, numerology, crystal therapy, chromotherapy, mineral nutrition and mental balance. With the Navratna necklace all gems are worn at the same time and the subtle effects work gradually and forcefully, producing the subtlest, yet most complete balance of the chakras.
