AOA Circlet Research - Part 2

Here are two more images of circular jewerly from Gotland.

This one is from the same reproduction supplier as the first one posted

And this one is from an actual grave find... From the Polotsk National Historical Cultural Museum and Reserve (http://polotsk.museum.by/en/node/129)

Twisted ring from island of Gotland. 11th century. Gold 900*, filegreed. D-25,0.
Excavations by V. Bulkhin.
Upper Castle, Polotsk, 1978.

All of what I am finding looks like a large gauge metal wire with a smaller wire or multiple wires twisted with it. More specifically two small gauge wires twisted with one another, and then that new created twist then twisted with a larger gauge wire. The terminals all seem to either be animal head or tendril like scrolls… More research on actual grave finds is needed, but I think this has me going the right direction
