These wonderful pair of Italian Murano intaglio etched Mazzega unusual table lamps are for high drama and beauty. Gray on black and black on gray... frosted glass. The reverse design on each lamp makes quite the statement on either side of a nightstand or buffet. At night, they cast a beautiful subtle light... not for reading tho. The opening at the top of the lamp/glass is 6.5: Wide. There is a slight variation of .5 inch beach each lamp height, because they are hand blown. They sit on a white metal round base with a gold cord. They have the original European socket which can be changed.
