I'm in the process of making steampunk jewelry: chokers, earrings, pendants.
Here's an example of chokers, earrings, and pendant I made:
Edit: just added four pendants I created
I'm strongly considering selling pieces like this online and locally. Chokers would have to be a custom thing since the ribbon would have to fit the neck, but can give examples online of the work and people can ask for them. Each would be unique due to the parts involved.
Of course I plan to keep a few pieces for myself to wear. :)
Naturally the thing to do next is show off the pieces and poll people as to what they'd think would be a reasonable cost for the item. I'm thinking the chokers could go from anywhere between $10-20 depending on the complexity.
