On the reverse side of the same case, we can see this display of three necklaces..., except the coral constructions are not really necklaces, but rather are headdress ornaments. (They don't hang around the neck, but from the elaborate head gear worn by married women). These nearly always include Mediterranean coral, black glass beads (local or imported, and less often green), and nice silver pieces (possibly from India as much as local products).
The necklace on the right is composed from large seedbeads, made into a netted construction. This is said to come from Baluchistan. Afghan women also make flat bibs, where the beads are worked similarly.
