although old, mine could be a later date copy made by the Venetians.

hopefully we will get clarification from the bead conference.

here is a quote from Beads from Borneo

The Lukut Sekala, the most prized bead - $4,000, if you can find anyone to sell you one. Its price rose 10,000% in the quarter century since Southwell bought it.

Its origin is unknown, but perhaps early Islamic or Viking. I have not seen a parallel in such collections, but the technology fits.

Furness (1902) reported that Chinese merchants sent a Lukuk Sekala to Europe to be imitated. The Kayans weren't fooled.
