BLUE GLASS DECANTERS

Im searching for info on this pair of matching blue glass wine decanters or carafes. They stand at 10.5" from bottom to lip and 13" from bottom to peak of dome on stoppers. Both stoppers have corks completely intact and bottles seem to be unused. There is a seam along the side starting from the bottom and ending right before the lip as well as a seam on the side of the domes. There is no pontil marking. The embossing on the front is a raised circle with 4 circles indented (kinda like 4s on dice). There are 3 raised rings around the neck. The embossing pattern matches with other glass that I've seen by Holmegaard, but without the Viking face or Fleur de Lis in the middle. There are some small bubbles throughtout both decanters. Any help would be greatly appreciated. Thank you.
