Are those wedding rings?
They sure look like wedding rings.
Yes. The NAZI Gestapo confiscated all their belongs when they captured them and transported them to concentration camps.
As is true with much of what was seen in Schindler's List the scene which showed eyeglasses...hair...religious symbols...and gold teeth being inventoried it seems highly likely that wedding rings and other types of jewelry were also collected,melted down and the proceeds found their way into Goering's Swiss account.
