Cultured Pearl brooch, goldtone, excellent store condition.

Beautiful cultured Pearl brooch, kept in this Coro box . I actually don't see a Coro stamp on the piece, but my aunt was really good about keeping everything in the original boxes. Also when I did research on the Coro company, apparently when they started making jewelry under the name Corocraft around 1948, a lot of the pieces were unsigned. But, I can't guarantee it's Coro...
The box has the original price tag on it of $2! The box has a store gold accent to it, and is in pretty good condition considering it's age. There is a little bit of green on the underneath of the one flower petals, but depending on the light, you can't see it. Let me know if you have any questions, and feel free to make me an offer. Thank you for looking.
