Rune Necklace Celtic Abstract Bead Vintage Moroccan Astrological VTG BeadRage

So this piece came out of my original 1990 opening line at the Excalibur hotel - I have a couple left in 3 colors color.  Not entirely sure but could be Moroccan. I have no clue what the material is made of.  The big beads are 12mm in size. Perhaps Islamic? Astrological signs? 15" in size.  Choose your color - Red - Black and white or multi-color
