Amethyst? Natural Stone Brooch/Objet d'art

This is a gold-tone brooch featuring a large natural stone. It measures approximately 14cm wide and 8.5cm tall. While it's a brooch, it would also look lovely as a room decoration.Please check the photos as the brooch pin is slightly bent. Otherwise, I haven't found any dirt or scratches, but I've listed it as slightly damaged or soiled because it's a vintage item and has been stored at home. Please refer to the photos. excellent for everyday use. excellent materials and excellent craftsmanship ensure long-lasting durability.
