In the 20th century, beautiful ancient stone beads from Afghanistan became available to collectors.

Afghanistan was, however, the source of the tabular and lenticular beads, which showcase the beauty of the stones, many of which are translucent.

The coveted long bicone beads, as well as leech beads, also came from Afghanistan.

Occasionally the beads are further embellished with spots, circles, or equatorial bands.
