Is Copper is Entirely Proper?

I have a pile of these antiqued copper findings lying about, so I decided to do something with them. I may need to get a proper bail for this necklace though. I don't like just using a jump ring when the chain is intended to slide freely. Would it be better if the necklace used a gear ring like that on the earrings, or do you think the necklace is acceptable if it uses a different design?

I also had these chandelier earring pendants that needed to be put to some use or other. Here are my solutions. On the left, I took advantage of the contrast between antique copper and shiny gold. I like the effect, but since I don't intend to wear it, I need input from those who might. On the right, I made something simpler with clock hands made of stamped metal. The patina is fairly consistant despite the varied sources.

The next earrings use more of the bright copper in my previous posts and a 10mm amethyst bead along with my usual clockwork embellishment.

And last, one of these things may not be like the others. A bracelet with silver-colored findings, the last of my rhinestone spacers, and a handful of dyed druzy agate beads. Much less strampunk. I am also not so sure about lobster claw clasps. Magnets or toggle clasps may be easier to use. What do you think?

As usual with these posts, I must apologize for any photography incompetence.
