Picasso hasn't drawn this black tree with the gray background, though the natural stone is named for his style of art. Scallops make the bezel holding the stone in place.
The back has a cutout small tree as well, showing the stone's back.
The overall size is 1.2" wide, x 1.9" high and 0.3" deep. It comes with a soutache cord adjustable necklace and weighs 0.7 oz.
