Steampunk jewelry, often misspelled as "steampunk jewelery", is a pretty broad topic. It can range from necklaces and rings to watches, earrings and more. Given that gears and mechanical parts play such a large role in steampunk jewelry, I've decided to include listings for various parts at the left as well. So if you are creating any victorian/steampunk jewelry, you'll be sure to find what you need to craft it.
The key to the steampunk aesthetic is the combination of metal and other materials. In the case of jewelry, this is often brass or silver and some sort of fabric or leather. If you are creating this from scratch, don't be overwhelmed. There are a vast number of jewelry crafting resources online and many can help you with the difficult bits of joining metal to fabric or leather.
