Coro Pin

Here's a Coro pin marked Coro Des. Pat. Pend. Missing at leaste one stone. Found an example here...http://www.emcity.com/royal.htm. Only difference is the end piece--either this piece was made with different stone combos or this one had the bottom stone replaced with the blue one. Looking at the example I found, it should be a red stone, not blue. Ah well, going into the "fix it" pile for now, but still a pretty piece.
