I love this collar for showcasing pendants that can sometimes get lost on other necklaces that hang lower.  With a width ranging from 2.5 to 3.5mm, this torque has presence, but is narrow enough for most pendant bails to fit nicely. The center of the necklace is the dip for perfect placement of a pendant within the zigzag. It's hard to capture on the photos (I tried) but the top of the torque is curved, while the bottom half that would lay against the body is flat.

This is a vintage piece and so has the expected tarnishing and a darker overall color than a new copper piece would.  It has not been cleaned or polished.

*Pendants in the photos not included, for reference only.  I didn't have a copper pendant so used an earring for one example.
