Sanchez Coello, Alonso. Portrait of the Infanta Catalina Michaela of Austria Hermitage ~ part 11

The picture has something of this: people, portrait, veil, wear, necklace, jewelry, woman, face, costume, fashion, dress, model, queen, princess, man, crown.
Perhaps it’s a close up of a painting of a woman in a black dress with a gold chain around her neck and a tiara over her left shoulder.
