This listing is for a green jade wrist mala/ bracelet for meditation.  There are 21 green jade beads on the wrist mala and each bead measures 7mm approximately.  The beads came from Nepal and strung it by myself in the US with love.  Prayer Mala or beads are usually used by Buddhists around the world especially in Tibet, Nepal and India and used for meditation, counting mantras, and prostration and those counters are especially for counting when you do prostration or in a retreat for counting mantras.  Malas are worn on the left wrist while not in use.   Please email me for more detail and i will be more than happy to assist you.
