1880s Ambrotype Portrait Cufflinks

Very Rare cufflink set from the 1880s with Ambrotype portraits. (Ambrotypes (or collodoin positives) were a type of photograph where an image was created under clear glass. The proccess is intriquing. If you are interested you can read about it on Wickipedia.) I see brooches like this from time to time but this is the first cuff link set I have ever found of it's kind. The cuff links are rose gold in color and I am assuming they are plated because I see no hallmarks to indicate other wise. The photographed portraits are of two different young women and judging by the hairstyles I am placing the date in the early 1880s. I believe the women were sisters, that is what the original owner told me. Each portrait is circled in a decorative wire frame. They measure just about 1" across and have a fixed back closure. If you are a cufflink collector these beauties would be a wondeful antique addition for you but they are also perfectly funtional and could be worn by a man or a woman.
