Intro

Coro jewelry is one of my favorites and I often find myself needing to research pieces.     Realizing that I hop all over to remember all the links, I thought it might be helpful to consolidate them all in one page.    Many thanks to all the wonderful websites shown below that have helpful info for researching Coro!!!  

Please, if you know of other links that we can add, or find a link that is no longer working ,etc, let me know!  I have also included some "basic" tips.  If you disagree with them, or have better info, please don't hesitate to let me know!    The more I learn, the more I know that I don't know!

Basic Tips:

Copyright Symbol:  If your piece shows the copyright symbol in addition to the Coro mark, it generally means that the piece dates to after 1955.   Many jewelry manufacturers switched from patents to copyrights at about time.  So, it also means that if there is a copyright symbol, it is not as likely that you will find a patent.  Although I believe there is some overlap during the 1954/55 time frame.

Signature / Mark Style:  The Illusion Jewels website has a terrific page with the Coro marks here.  Keep in mind that marks were often used for a number of years.   For example the commonly seen mark of the name Coro in script, was used for many years.  So although it is indentified as 1919, it was used throughout much of the history of the company.

Finding your piece in a vintage adverstisement is a great way to establish a date.   Generally, jewelry styles changed quickly, so ads are a good snapshot of what was selling at the time of the ad.   Once in a while a style would be repeated in other years, but this seems to be fairly uncommon.  

Listed below are some terrific sites with Coro ads.    I've only included links that go directly to a page with Coro ads.  There are some other sites listed on our "Lots o' Links" page that include Coro ads among a general grouping of ads.   So, check there for more places to look.

Design patents are also a great way to date your piece.  Below are some links of sites with Coro patents.  Some also have examples of pieces that match the patent which is very cool!
