A look at what is currently available on eBay
How will I know if its a surgical steel, stainless steel or a sterling steel necklace?
I don't think there is any such thing as sterling steel, sterling silver but not steel. As for the other two, if the necklace is made from any of those materials they will want you to know about it because it's more expensive than plated copper to produce. It will say on the tag, or be stamped into the clasp.
