天珠藏语叫（si ， 斯）汉语译为“斯”或“瑟”，又称“天降石”。在《藏汉大辞典》里天珠的解释为：“亚玛瑙，猫睛石，一种宝石，俗称九眼珠。入药能治脑溢血” 。最早的天珠为象雄天珠，象雄天珠诞生于古代横跨中亚及青藏高原最强大的文明古国--古象雄王国，它是雍仲本教的圣物，是藏族七宝之首”

象雄天珠由大成就者和高僧大德供奉加持装藏供佛或者伏藏传世而来，现存世(老)天珠皆为古人遗存，无比珍稀罕见。象雄天珠是目前有实物见证的最古老、至纯的天珠，是极为稀有难得的珍宝。 象雄天珠是古象雄文明时期的产物，从医学的角度而言：天珠是治病救命的良药，有着不可思议的神奇功效。

此天珠为一眼天珠，规格：长43mm，直径12.5mm，重12.4g。一眼天珠代表，光明之珠、增长福慧、清明舒畅、达成愿力。可使心绪清明、心情愉悦，促进智能增长。单眼天珠，数量非常少。

天珠的矿岩成份中含玛瑙及玉质，属半宝石，且纯正的老天珠的存世量十分稀少，因此物稀为贵。在藏人眼里，天珠相当于钻石，多半是串成项链，戴在妇女身上当饰物，出席盛会的时候拿来炫耀地位，并不是宗教法器.在配戴的设计上除了实用之外，美观大方也是设计的重点。

因为老天珠的数量 非常罕有，不像其它的珠宝可以开矿挖掘，也因为天珠不可思议的磁场感应及灵性，加上历代持有者的修持、配戴，促使其价值的提升，物稀为贵，故成了有心人争相收集典藏之珍宝。
