Made from yak bone. The color is brown. I think the first and third photos best represent the actual color. The beads are about 0.9 cm in diameter, with the master bead being a smaller diameter. The rosary is about 48 cm long when laid flat. Each bead is hand-carved, so the expressions vary. By the way, the skulls this time have deep carvings and clear expressions. It is said that skull rosaries are favored and used mainly by esoteric practitioners among Tibetan Buddhists. A yak is a bovine animal that lives in grasslands, tundra, and rocky areas at altitudes of 4,000-6,000 meters, mainly on the Tibetan Plateau. The outer, tough, long hair is used as material for tents and ropes, and its milk is processed into butter. They also carry heavy loads on their backs, and their meat is eaten as a valuable source of protein. Their bones are also processed into rosaries, making them a versatile animal that can be used in many ways.
