The shoe is has a beaded edge which was fashionable during the mid to late 1800’s. It is signed by the silver maker, though hard to read. It is hallmarked in Chester, England in what appears to be the date letter for 1892.
It closes with a simple C clasp and a pin which extends beyond the brooch, both signs of a 19th c pin (or earlier). The C clasp has been rather crudely replaced with cold solder, as these brooches are very difficult to repair - they tend to melt under the heat of a traditional solder. I’m sure that’s why this one is repaired this way. A modern fix would involve a laser solder. But it is on the back, so does not detract from the beauty of this little gem.
