Portrait of M. Velichkina, nee Baroness von Klodt Yurgensburg Vasily Ivanovich Surikov (1848-1916)

The picture has something of this: people, portrait, necklace, popularity, fame, choker, royalty, wear, famous, profile, jacket, princess, woman, leader.
Perhaps it’s a close up of a painting of a woman in a black dress with a necklace on her neck and a diamond.
