Hi Rosanna,
I wouldn't have thought Hebron, but either Akosu/Akoso or perhaps Bodom. Just my thoughts! Lynne

Hi Rosanne,
I don't think this is a hebron bead. Color, lustre and eyes don't look right to me.
Can you show us the perforation from both sides?
A krobo bead is an interesting thought.

Hi Hans & Lynne -
Here are the photos. It looks like the core is black (sorry about the piece of raffia sticking in there) so yes Krobo is possible. I'm not used to seeing any green Krobo particularly small, shiny ones so let me know what you think! Thanks for your comments!

Hi Rosanna,
It is a unique one. IÕve never seen such a bead.
But the color green occurs in beads from the Krobo area. Also the use of small beads as eyes as one of the eyes in your bead. There are also green Akoso beads. The shiny surface occurs too when the heat of the furnace is high enough and no grinding afterwards is used.
Added are two photographs of beads collected in Benin with a black core and shiny surface and just about the same size as yours. The only examples I have. But were in Africa they were made is an enigma to me.

Pity you did not call Amsterdam on your last trip, Hans

PS these two beads are also in the collection of the Picards on internet

the odd thing is, I have found these in association with Ghana powder glass beads and with Mauritanian powder glass beads......any light?
Sorry for the phone image

The air bubbles/impurities in Rosanna's bead appear to follow a circular pattern, around the centre of the bead. To me, this would indicate it is a wound bead, and not a powder glass bead.

I don't know much about beads outside the European trade bead era, but I wondered if this was an ancient stratified eye bead or a very small Hebron.

I don't see any evidence of the granular structure of most powder glass beads.

BTW it was found on a mixed strand of African trade beads.
