A very organic magnificent round vase in blown Murano glass, late 20th century, signed by Costantini, the deep black body worked with an extensive and sophisticated iridescence that refracts the light with rainbow colors. The shape is accented by four sculptural swirls, freely applied in relief in clear Murano glass worked with bubbles that add texture and a modern twist to the decoration. Measure: Diameter of the opening is 5.5 inches.
