Steuben prisms, I believe.

I believe these to be prisms made by Steuben. Those in the straw opalescent colour are five inches in length and the green ones are six inches. Notice the angle cut or bevel on the front of the prism surrounding the prism pin hole. Another of the detail images shows the profile on the edge of the prisms. I will look up the shape number tomorrow. I have run out of time now and bed calls and of course the dogs are giving me the look too. They won't go to bed until I do.
Good night. I will add the number tomorrow.
Sincerely,
Lisa
