This great pin's center pops out to insert a picture of that special person in your life. The window fits very firmly! The photo is then accented by half pearls. When viewing with a loop all pearls appear to be original except for one. They used an old pearl of great color match. The only reason I found it was the prong mounting. The pin & C clasp look to be original. We find no repairs. The backside is marked 9ct. gold as well as a makers mark. The makers mark was not as deep as the ct mark so is hard to read. It is 5 letters in a rectangle. It maybe CKYCO. Size is 1 1/4" in dia. & will hold an almost 1" in dia photo. Circa 1905. Please read ABOUT US & TERMS OF SALE.
