This brooch intrigued me! It is called a "Dutch Gold Brooch" and comes on it's original card. And the design is a beautiful monogram, in this case, the letter "N" (I think!). Please note that even though the card says "Dutch Gold." this is not true gold, but appears to be a metal with a gold finish. If you study the back of this piece, you will see that there is not a typical brooch clasp, but instead, little prongs that clip on. I am mystified as to how this was meant to be worn?? Attached to a lapel? Sewn on to something? I would love more information if anyone is familiar with this type of brooch. Beautiful monogram design!
