Large signed Chanel Robert Goossens for Chanel gripoix Byzantine style brooch. A similar necklace style dating to 1970 is found on page 26-27 of the text Maison Goossens Haute Couture Jewelry. Marked Chanel and three stars indicating that older date. Condition is excellent, in original box. Offers considered, especially on multiple purchases of Chanel. After talking with Gripoix these appear to be their glassmakers and have been set later or set based on the designers sketch.
