Tibetan 3 Vajra Dzi Bead 三金刚杵天珠珊瑚手串
3 Vajra Dzi Bead’s 3.5cm coral Bracelet
天珠，又称“天眼珠”，主要产地在西藏、藏东、不丹、锡金、拉答克等喜马拉雅山域，是一种稀有宝石。天珠质地为石页岩，含有玉质及玛瑙成份，为藏密七宝之 一，史书记载为 “眼石天珠”。
西藏人至今仍认为天珠是天降石。其历史可溯及五千年前，当时西藏人发现此矿具有强大的磁场，乃 开采此矿并研磨成杵、圆板等形状，由于当时之工程技术并不发达，故仅能取得颜色灰白、无明显纹路之浅层矿石，因此西藏人绘制各种吉祥图案于上（如宝瓶， 莲 花， 虎纹， 眼纹， 金刚杵，线条等），经高温处理使颜料深入矿石内，若再经大修行者加持，更可拥有不可思议的神奇力量。非福报深厚者，实无缘得此天降圣石。
Tibentan Dzi bead is a bead stone of mysterious origin worn as part of a necklace and sometimes as a bracelet. In several Asian cultures, including that of Tbet, the bead is considered to provide positive spiritual benefit. These beads are generally prized as protective amulets and are sometimes ground up into a powder to be used in traditional Tibetan medicine. Beads subject to this process have small “dig marks” where a portion of the bead has been scraped or shaved away to be ground into the medicine.
The most highly prized dzi beads are made of natural agate and were apparently manufactured in ancient times by an unknown people. There are also new dzi which gain popularity amongst Tibetans.
