a portrait of a young girl wearing an emerald earring. The girl is looking over her shoulder at the viewer with a sly expression on her face. naturalistic style with soft, muted colors. The girl's face is the only part of the painting that is in sharp focus. The rest of the painting is done in a soft, blurry style. The girl's face is lit from the left, creating a soft, halo-like effect around her head. The emerald earring is the only source of light in the painting. an oil tronie painting by Johannes Vermeer.
