Late 19th Century Graduated Green Agate Beaded Necklace - Possibly Moss Agate

Beautiful Late 19th Century Graduated Green Agate Beaded Necklace.  This may possibly be Moss Agate but I couldn't quite make up my mind on this one.  It has natural imperfections in the stones and inclusions from its formation.  The beads range from 10mm at their largest down to 6mm at the smallest.  Along the bead line there are also gold coloured metal beads.  It has a hook and loop to fasten.  Its a lovely piece with some weight to it.
