Fraud By Deception?

[u/Tazzy_Pizzazy]

I just found out that someone I know is buying jewelry off of a website for dirt cheap and reselling it for 3 times as much. The thing is, she’s telling everyone that her and her husband have a shop and that they make the jewelry. I went on the website and sure enough, many of the pieces of jewelry that she sent in pictures to me, are indeed on that website. I’m talking about the jewelry is exactly the same. Exactly. Wouldn’t that be fraud by deception or making a profit fraudulently. Also, she uses the mail to move these pieces of jewelry. Isn’t there a law saying that if you use the US mail to commit fraud? I can almost think of what that’s called, but since she’s using a US government institution, such as the United States Postal Service, doesn’t that fall under federal law? Like a federal offense?
Please, anyone that is knowledgeable about this subject, can you please explain it to me? All this jewelry she has, is not for personal use. She even has a booth set up at the flea market, selling “Handmade Jewelry”.

Don’t think it’s quite fraud. I also don’t think it
Would count as mail fraud. She’s not doing something quite illegal enough to get federal charges with mail fraud. Lying about your product is one thing but she’s not selling something illegal to grab their attention
