Looks like a German couple (rings on the right hand...)
You noticed the bride wears a wedding band and a diamond ring. I was born and raised in Germany and when I grew up the bride wore the same band that she got from the groom when they got engaged.
So maybe it's something new. I haven't been back to Germany since 1979 when my husband was transferred back to the States and he retired from the Army after 21 years, 11 month and 7 days of service. Plus two tours in Vietnam for which he both volunteered. BTW we married in Germany
