I have loved this 2 by 1 & 3/4 by 1/4 inches brooch a long time. This rustic scene of pathways and bridge over water, and a distant villa, is from the 19th century. It is unusual, to my eye, for its bold impressionist style. It might have been painted just like this by Van Gogh. It has been tested to be 14 karat gold and it has a modern safety clasp also 14 karat. So different from the more typical micro mosaic landscapes with sharp lines of demarcation between objects and colors. It has some very light scuffs on the black glass--they were extremely hard to capture with e scanner because they are practically invisible to the eye.
