The second paperweight is, as noted above, Murano. A nice gathering of tight pastel millefiori canes. Check the bottom for a faint 3 Fiori mark. Move it around in the light to catch the stamp, if it's there. It also looks like 3 Fiori-made to me. It could be marked, but the company didn't mark all of their paperweights.
The first weight seems new Czech or even new Polish. Maybe somewhere else in Eastern Europe. I'd go with European, but not the U.K. since the glassmakers in the U.K. are doing hyper-quality work, and although the swirl weight is colorful and pleasing to the eye, it's not up to the caliber of most new U.K. paperweights. I don't think it's Chinese; however.
