The medium-weight canvas is plain woven; it was lined in 1968. The ground is white. There is a very thin and transparent warm brown imprimatura. The painting is rapidly and deftly executed in fluid, opaque layers, blended wet into wet, the light passages in rich paint, the dark areas much thinner. X-radiographs show that the ring suspended from the sitter's waist has been shifted slightly to the left. The sitter's right hand is heavily retouched; the retouching lies over the remains of black, suggesting that the hand had been painted out by the artist, that the artist's black paint was removed during a subsequent restoration, and that the form then had to be reintegrated. The paint is somewhat solvent abraded in the background and in the pure blacks, and the impasto was very slightly flattened during lining. There is extensive retouching in the background, and scattered retouching carried out in 1968. The dammar varnish applied in 1968 has not discolored.
