This listing is for a yak bone or conch shell pendant with brass cover. There are four choices of pendants which are dark yak bone, conch shell, Turquoise and coral, and Yak bone. Please let me know with any other questions. The script is the mantra of Avalokteshwara the Buddha of compasstion and it means "hail to the jewel in the lotus". Mani means jewel and pema means lotus. OM includes three letters which are AH, O and MA and it is also Om Ah and the last letter HUM together makes the word OM AH HUM. This word is a blessing word, because whenever we bless something whether we are blessing the earth or food or whatever Tibetan people say OM AH HUM. After that you visualize that it is purified. So this mantra is very powerful mantra. There is no Tibetan people who don't know OM MANI PADME HUM mantra. We say this mantra every time when you see a dead being, sick person or animal. We visualize that this mantra will help the being. That is why Tibetan people wear wrist malas with these designs. Please let me know with any questions.
