Vintage RARE DESIGNER brooch flowers thistle? Gold Stunning estate vtg berries

ABSOLUTELY BEAUTIFUL! This piece is really something special! It has a spot for the designer name but seems this piece was missed when being stamped! It's a bigger piece with the most stunning detailed flowers! If you know what kind they are please lmk. I know this is a higher end designer piece, the estate owner said the same and was told some history but couldn't remember! I can't find another piece like this at all, it looks like gold gilt or a good plating. It's a brushed gold texture with tons of little realistic details . It reminds me of thistle or berries of some sort, It's in excellent condition and is 3.5" tall by 1.25" wide at widest. It's a heavier piece but the pin on back is big and supports it just fine. This would be beautiful on a fall or winter jacket coat collar. if you know the designer please lmk.
