One vote for the bangle. I think the motifs would be too busy with the clash's many facets and there would be too much softness with the 2 fabric cords plus the chain of the motif. The only thing really solid would be the clash, and that is visually broken up. Also, the motif chain might get snagged on the clash spikes (but not sure about that). The bangle would be a better contrast and help to anchor the visually softer/busier pieces (imo).
