Arfvedsonite
- Mount Malosa
- Zomba District
- Malawi
- 4.3 × 3.8 × 3.1 cm – Miniature specimen (fits into a 5 cm cube)
Aegirine is an iron sodium silicate, and a member of the amphibole group (Hawthorne et al. 2012). Brooke (1823) named the species after Johan Arfwedson [sic] (1792-1841), Swedish chemist who discovered lithium.
Arfvedsonite forms blocky crystals to 1.6 × 1.3 cm on a microcline matrix. At Mount Malosa, arfvedsonite is significantly (magnitudes?) rarer than aegirine. This is a choice example. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
