This is a vintage strand of true marbled Bakelite prayer or worry beads strung on a simple gold tone chain. The colors within the beads are primarily dark green and sort of butterscotch which I believe is a combination called Creamed Spinach.
There are 14 oblong beads that measure 12mm x 10mm. At the end of the strand is a uniquely shaped bead.
From end to end, the item measures approx 11-1/2".
The beads smell strongly of formaldehyde when simply rubbed with my fingers.
