My brother gave this set to me and it's gorgeous but I have no idea where it's from or who manufactured it. I've attached some pictures of the set and decorated box it came in, as well as the mark on the bottom of the glassware. If anyone can help me figure out information about these pieces, or at least point me in the right direction, that would be great! Thank you!

This is the mark I'm trying to identify (it looks newer than everything else in the set):

This is the box the set came in:

This is what the set looks like all together (all of the glassware says "Freiburg" on it):

Again, any help would be appreciated! Thank you!
