Half natural, half etched Chung dZi.
The Tibetan I bought this from had only recently escaped over the border from Tibet and brought this bead with him. He called it a Goat's eye dZi. Only the left side has been etched, hence the graduated colour change. 16mm x 16mm. Extremely old, and covered with martik.
$150 approx. value.

2 pure dZi half beads.
Either of these beads if complete would have a value of several thousand dollars. The bead on the right is so worn that the striping of the agate shows through the etching. If either of these beads were complete they would be worth a minimum of $5000! I have seen similar broken beads sell on ebay for $400. My research leads me to believe these beads are at least 2500 years old, in spite of the "History of Beads" timeline stating they are from 700 AD! Further inspection of the catalogue numbers actually state the date as unknown.
