Vintage Costume Jewelry necklace

Stunning Agatha (Paris) necklace. Very sparkly. Bought in 2005 for a wedding. Worn once! Ideal for a glamorous special occasion. It’s a little on the small side. I’d say an XS size. You could add a longer chain at the back to expand it a bit. I’ve taken a photos with and without a flash but I promise it’s sparkly. It’s just hard to capture in photos.
