I have hung on to these gold & rose gold filled cufflinks for 20 years. I always loved them but they just weren’t in pristine condition so I could never bring myself to use them. I finally decided not a one of us is perfect, and this piece didn’t have to be either! These are circa 1870’s and wouldn’t it be wonderful if they could talk to us about their previous life!? I believe the monogrammed ones are glass that has been overlayed with black, then carved through. The cameo piece most likely is glass. Monograms were so fancy, so I can make out the “P” & “S” but not sure if the other two are “H” or “HF” or maybe something else all together. Whatever they may be, they are fascinating and to think almost 150 years old!
