Akhtaragdite (Akhtarandite, Achtarandite)
Akhtaragdite (Akhtarandite, Achtarandite) depending upon transliteration. A wonderful conversation piece! From a site described by the Moscow Fersman Museum in 1976 as Akhtaranda River, Yakutsk, ACCP. The site is under water, thanks to a power dam and is now known as the Chernchevsky (or Vilui) Reservoir, Wilui River, Sakha Republic (Yakutia). Probably collected in the 1920s (pers. comm. D. Hogarth). Originally described as pseudomorphs after an unknown mineral, it may be after Wadalite or another mineral -- current English literature seems unsure. This specimen measures about 9 cm x 8.4 cm x 5.5 cm and includes the Fersman Museum label. The crystals average about 1.4 cm across the edges. Akhtaragdite (Akhtarandite, Achtarandite) |
