so i agree for these sorts of beads the term "Neolithic" is always used rashly- it may only refer to the technology rather than any time period, up to C20th... and craftsmen and lapidary metal hand tools are known.
Maybe there will be even more convincing visible evidence one day that links the beads most specifically to one tradition, whatever the descriptive name may be.

i generally see Lantana beads as elongated shapes, of cornelian, and recognise many as the typical shapes from India.

meanwhile those pottery beads- i've been told several times that they are found in sealed
burial jars in Mali. etc. has anyone here seen them being made?
