Part of the fun of shopping for and sourcing vintage jewelry is learning the history and stories of brands. I especially love playing detective, with a newly acquired piece, and discovering a new brand and the story behind that particular designer or company. One of the best websites I have found to help learn and identify a mark is Researching Costume Jewelry. They have an extensive list of jewelry designers and manufacturers sorted in alphabetical order, so it is fairly easy to scroll through the list and locate the mark or name you are looking for. This also is really helpful if you are trying to date a piece of jewelry. For example, I was recently trying to date a Kenneth Jay Lane brooch and with the help of RCJ, I was able to quickly date this brooch to be from the 1960s to the 1970s.
I highly recommend Researching Costume Jewelry if you would like to learn more about a piece you own or are considering buying.
