Big Round Banded Agate Bead from China-Tibet
Big Chinese agate bead of dark brown colour. This type of bead can be found in the Himalayan regions, like this one, but also in the Persian area. Ancient, very fine usage patina, it presents signs of age that could not reproduced artificially, and some small dig marks. The shape is flat round. We suppose it dates to the Tang Dynasty (from 618CE to 907CE), supported by the picture visible in “Sparkling Splendors – The Thaoshi Zhai collection”, pages 218, picture 230

Ancient and antique agate beads, that are diffused from the Mesopotamia (4000BCE) to Himalayan regions and beyond until 19th century, often are not decorated, however various methods were used in antiquity to alter the colour of the stone. These treatments made the crystalline layers or banding more prominent and thus enhanced the appereance of eyes and stripes. This in turn made the beads and the stone more desirable for personal adornment and for their use as amulets.This bead seems to has been treated as dZi beads for the dark colour, but without any decoration like “eyes” or “stripes”.
