Pietra Dura Pansy Brooch, Victorian

I feel in love with this piece immediately. I love pansies, and the sentiment expressed by them. The colors in this piece are lovely and it is in excellent condition. What I find most unusual, though, is the wide, 9 carat, brooch frame, with the flowers around. Normally pietra dura pieces just have a plain, round frame. This lovely brooch is circa 1870, and it measures 1 and 1/4 inches North to South, and 1 and 1/2 inches East to West. The back of the piece is all original. I am not usually that great a fan of Pietra Dura, but this one really tempts me. I may have to keep it!
