This set of five cut glasses and matching decanter was likely produced around the mid 20th Century, but that is really just a guess on my part. The label on it reads that it was made in Czechoslovakia so that dates the set to the early 1990s at the latest.
The photos do not do this set justice. It was very difficult to capture the true colours.
The glass is an amber or topaz with a red stain. The flowers and foliage are cut to the amber. The red has darker undertones, it is not crimson or scarlet. You can see the amber in the neck and in the stopper. There are lots of gilt/gold decorations on both the decanter and the tumblers. It truly is a lovely set.
I saw something similar online attributed as Egermann Glass, but I have no idea if this is Egermann or even Egermann style.
