what I see here is a fairly typical Moroccan necklace with the strange tinted modelled clay-like composition "coral" barrels, those small metal beads made out of a coil of wire, and these big amber colour beads which are made (in Morocco) from softened synthetic resin otherwise known as real plastic and you can see the squidge marks! I have some which even have discernible fingerprints of the maker.
By coincidence I've just written a short couple of paragraphs for the next Bead Soc. of Great Britain newsletter about imitations of Amber which includes this stuff.
