I have this orange / peach color pearl from a Victorian stick pin I acquired at a garage sale. I’ve seen a lot of pearls but this one almost looks translucent, it’s scratchy against the tooth like a normal pearl, but the color and iridescence have me wondering if it’s some kind of pearl I’ve never seen before. I took it out of the pin due to the pin causing discoloration / reaction on the pearl. Thanks for looking and any insight!
