This is my latest necklace where I used my only gear that isn't gold in color. I was really happy to find that gear because I love the look of gears in jewelry, but I don't wear gold/bronze/copper jewelry.
The beads have a metallic sheen that changes colors as it moves in the light, and it's the only color in this piece.
This one will be up for sale soon.
EDIT: Didn't sell.
