Lamp base in the style of lamp bases from the end of the 19th century, probably dates from the beginning of the second half of the 20th century, the base and the collar which supports the socket are in gilded metal, the central part in turquoise blue ceramic . I intentionally multiplied the takes to give a better idea of the beauty of the blue. Depending on the light, the shades of blue vary. The 2nd photo gives a very faithful rendering of the blue. With the socket the lamp is 47cm high, the base is 17cm in diameter, traces of use but no defects.
