Yes, they were. The necklaces mostly before the Viking Age proper, in the Vendel period, but there are still some pretty spectacular finds from the V.A itself. The bracelets were used both as decoration and as currency. The latter kind is very common, and many of those are torc styled. Run a google images search for Spillings hoard, and you should be able to find some good pictures of the various styles. Or you can look up the Cuerdale hoard - I think there were some torc style bracelets in it, too, but the research I'm doing with my research partner atm is about the Spillings bracelets. They were quite stylized in terms of patterns and shape, as you'll be able to see from the pics.
