The beads are made of natural Baoshan South Red Agate, which is a gemstone that is said to have a number of healing properties. The beads are smooth and polished, making them comfortable to wear. The necklace is made of a strong silk thread or cord, and it is adjustable to fit any neck size.It is said that the 108 beads represent the 108 delusions that humans are said to have. By reciting the Buddhist mantra "Om mani padme hum" while wearing the necklace, it is believed that one can overcome these delusions and achieve enlightenment. I would highly recommend this necklace to anyone who is looking for a beautiful and meaningful piece of jewelry that can also help them to connect with their spiritual side.
