Pair of Mid-Century hanging lamps in Glass and Brass - 1960s

High-quality pendants by an unknown designer, most likely produced in Sweden. The construction of these lamps is very minimalistic and elegant. Two brass rings hold a perforated metal cylinder, which is surrounded by glass blocks that are held in place by brass screws to the rings. Even the porcelain bulb holder is surrounded by brass, one of the details that add to the sense of quality.
