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.
I lived in Asbury Park, NJ in the '60s and stayed in a boarding house run by a Jewish woman who had survived the camps. She said some stayed alive by working for the Germans, searching body cavities of the recently gassed for anything of value that might have been hidden there. I wondered at how strong was the sense of survival that you would do such things.
