My Sweet Find

These beautiful pieces are one of my recent finds, and I'm familiar with the patterns and the different colors they come in, but when searching for the clear, I am unable to find anything but the Vaseline and other colors. I know that the pattern is wreath and shell and that it is opalescent. I'm not sure if the first two open vases are actually vases or if they are supposed to have lids. I'm also not sure who made this beautiful glass piece.
I would appreciate help with any or all the information on this please.

Thank you for everyone's help...
