Vintage Western Germany GIANT 1 1/2" Faceted Abstract Glass Open Back Loose Stones Destash Repurpose

Not quite sure what to call this shape? They are not a trapezoid shape. So I am just calling them abstract. I have had these stones for ever. The original box was labeled Western Germany. It is long gone. These very large stones are beyond gorgeous. The colors are superb. They seem to shift color when you move them. They have faceted backs that come to a slightly raised point in the center. View 2nd photo.

They measure 1 1/2" long. There are a couple of tiny nips on the edges one a few stones not worth mentioning. One has two scratches. See last photo. The paper you see underneath them is the original paper they came in. Not the easiest stones to photograph and show their beauty. Would make some stunning pendants.
