This is a decorative item I received from a high-ranking monk at the Potala Palace when I visited Tibet with my father about 30 years ago. I believe it is a valuable item. The yellow part is quite heavy, and I am unsure whether it is agate or glass. If it is agate, it may have the following meanings: ~Quote~ Agate has long been treasured as a talisman and amulet in Asia, including the Tibetan Buddhist sphere. Tibetan agate, which has eye-like patterns, is also called "sky eye stone" and is regarded as the eye of God, becoming an object of faith, and is a natural stone of great importance to Buddhists. The Importance of Agate in Tibetan Buddhism Role as a talisman and amulet: Agate has been used as a talisman and amulet since ancient times in Japan, India, Tibet, and other places, and was especially treasured in the Tibetan Buddhist sphere. Faith as a sky eye stone: There is a type of Tibetan agate called "sky eye stone" that has a pattern that looks like an eye. This was discovered on the surface rather than underground, and has been regarded as the eye of God and has been an object of faith. Relationship with Buddhist art and culture: In Tibetan Buddhism, the symbol of the Buddha's eye is sometimes used. The eye-like pattern of agate is thought to have such Buddhist meaning. In this way, agate is not just a decorative item, but is positioned as an important natural stone with spiritual meaning in the faith and culture of Tibetan Buddhism.
