Antique Kurdish Necklace with Coins from the Ottoman Era

A very unusual most likely Kurdish necklace, from southeastern Anatolia or Iraqi-Kurdistan.  The central pendant is a carved blue stone (maybe blue agate) and has three chain dangles with metal discs and a faceted carnelian. The hand made chain is decorated with blue and coral colored plastic beads. From the chain  dangle 26 one kurush silver coins minted under sultan Abdul Hamid II, the last Sultan of the Ottoman Empire.  The coins date the necklace to the early part of the twentieth century. The color combination of blue and red and the composition of the necklace is very pleasing. In very good antique condition missing only two orange dangles. The necklace is not silver with the exception of the ottoman coins which are above 80% pure silver.

• Length is 46 cm (18")
• The central pendant is 2.5 x 3 cm  ( 1 x 1 1/4") without the bale or dangles
• Weight is 82.8 g

My thanks to the esteemed collector Jean-Marie Criel for helping me narrow down the origin of this necklace.
