This brooch is from about 30 years ago. It has the brand engraving "grosse" in the center of the back. I purchased it from the mail order service Sony Family Club at the time. I've forgotten the brand, but I believe it was probably Grosse, a German brand. However, it was purchased quite a while ago, so I do not guarantee the brand. Please make your judgment based on the photos. I took the photos several times, but I apologize that I couldn't capture the logo well. I remember repairing the adhesive on one of the pearls, as it was about to come off. It was inserted into the pin and glued, and it seems to have loosened over time. It's a straight-type brooch that's not often seen, and it's about 10 centimeters long. All the sparkling stones are present. I am selling it to organize my belongings. As this item is from about 30 years ago, please refrain from purchasing if you are concerned about minor scratches, scuffs, or stains due to storage. I will provide additional photos if you have any questions. Please purchase after you are satisfied.
