Czech Decor - A mystery decor

Here is a decor that is a real mystery; I own in many colors in this decor (although none of these pieces are mine). Focusing on the pink decor you can see a white opal base color with streaks of pink covering the surface like granite. If they were seen together I do think they would display well. Here are my observations for each piece:

1. This shape could be Welz because of its shape and the black applied finial
2. This shape is most likely Kralik or Ruckl- They both did this shape
3. This shape looks looks like the pieces produced by German glass company Jean Beck although I haven't made any size comparisons
4. These taller pieces look like Rindscopf but I am uncertain because of the shape

Other colors seen:
gray, violet, light blue,yellow, gold, green and brown
