Vintage Silver Faux Turquoise Stone Pin Brooch

For sale is a vintage silver faux turquoise pin or brooch. This is an older pin, with a pretty ornate setting which complements the middle of the pin nicely. The stones are slightly greener in color than they appear to be on my monitor. This pin, while attractive and unusual is made out of unidentified materials. The pin has three pretty of what may be some kind of hard plastic, or they might be actual turquoise stone. Whether actual stone or hard plastic, or some other substance is unknown, but they are a nice color, and do have a nice appearance, with a beautiful sheen t o them. They also appear to be manufactured for use as beads, as one of them shows a hole on each side of the stone, which looks like it could be used as a stringing hole. Please see the listing photographs for a visual of this. The pin is stamped Silver on the back. I do not believe this to be sterling silver, but it could be a lower grade of silver. The pin measures approximately 2 and 1/16 of an inch across, and 14/16 of an inch high. The pin bar is slightly bent. It is very slightly wavy along the length of it.
