While the term "handmade jewelry" is used a lot to describe products, there's very specific guidelines in place by the FTC for the processes one can and can't use to be able to stake claim to this description.
Wikipedia has a good description:
"According to the guidelines of the FTC, in order to be stamped or called "handmade" the work must be made solely by hand power or hand guidance. This means that jewelry may be made using drills, lathes, or other machinery, but it must be guided by the human hand. This precludes the use of punch presses, CNC machinery, and casting, to name a few processes the use of which would make the jewelry not qualify as "handmade".
That's right, even if a piece is cast from a model carved by hand, since it is then produced by casting and not formed by raw materials (ie: metal wire and sheet) from hand it doesn't count. A piece of jewelry is automatically disqualified from "handmade" status if just one step isn't guided by hand, even if every other step of its process is.
All of our products that say "handmade" follow these guidelines.
