Before wearing Panna stone, also known as Emerald, chanting the correct mantra is believed to activate its astrological power and connect it with Mercury (Budh Graha). The most commonly recommended mantra is “Om Bum Budhaya Namah,” chanted 108 times with devotion and focus. This sacred mantra helps energize the gemstone, remove negative vibrations, and attract Mercury’s blessings related to intelligence, communication, business growth, and mental clarity. Panna is usually worn on Wednesday morning after purification rituals. Following the proper mantra, finger, metal, and timing can enhance the gemstone’s spiritual and astrological benefits for the wearer.
