Swedenborgite - Sold


Swedenborgite is sodium beryllium antimony oxide. Aminoff (1924) described the mineral, naming it after Emanuel Swedenborg (1688-1772), Swedish philosopher and theologian. Embedded in a corner of the crystalline calcite matrix is a colorless swedenborgite microcrystal. A red arrow points to the spot; and the mineral fluoresces blue under shortwave ultraviolet radiation. Linus Pauling led the research team that first solved the crystal structure of this mineral (Pauling et al. 1935). Rare stuff. I collected this specimen with Peter Lyckberg on September 3, 1991.
