Hi Anne,
As promised, some pics of 'Ambers' from North Africa

I am no expert, but can offer the following info.
Copal ( Milked plant based resin is used to make) beads which are sold to tourists as amber. This is made in the Souss region in the South and I am sure in other areas too.
Resin beads are made in Marrakech and are generally referred to as Saharan Amber
There are cross drilled beads on offer in Morocco which are usually said to hail from other west African countries such as Mali and Mauritania.
There are also Saffron dyed horn beads which are offered in many Tourist areas as amber.

I give this information based only on the production of beads which I have seen and the selection of beads which been offered in Morocco within the past 5 years.
I know that there is much more to learn, and shall endeavour to expand my knowledge on each and every trip.
