Landau Jewelry

Do not purchase this jewelry. I had a severe allergic reaction to a ring I purchased from them in less than 24 hours of wearing it. My ring finger is still peeling and literally has a red rash on it still after 2 weeks. I asked them for a refund and they said all sales are final even though its clear that whatever they are using is garbage metal. They do not stand behind their jewelry whatsoever. Im disgusted and out over 100 dollars.
