This is a vintage item purchased at a boutique, but the brand name is in cursive and from an overseas brand, so I can't read the logo. I remember it was expensive, but being vintage, it shows some signs of wear. The pin is a little weak, but I think it will be fine if the base is fixed with glue. The jewels themselves have a luxurious feel and look beautiful, but being vintage, two of the diamonds are slightly yellow if you look closely. Please understand this before purchasing. It's a rare and stylish piece with a purple color like amethyst.
