Strömbergshyttan "Diamond" crystal vase designed by Asta Strömberg. Designed by renowned Swedish glass artist Asta Strömberg (1916-2011). Made for the Swedish glass factory Strömbergshyttan in the 1960s. Made of thick, ice-blue crystal glass that creates interesting visual effects as the light refracts on the angular walls. An example of iconic Swedish modernist design. There is a signature on the bottom, but I couldn't take a good photo of it. It is in absolutely perfect condition. We can post it carefully packaged, in an insured, registered package.
