According to Spencer, the crystal shows "brilliant metallic lustre with silver-white colour, much resembling the crystals of amalgam (silver-amalgam) from the Palatinate (Rhenish Bavaria)"--by which Spencer was probably referring to the mineral moschellandsbergite
, which was not named until 1938.
They're all here, in multiple samples ranging in quality from "study grade" to absolutely superb: Freiberg acanthite and stephanite, Schneeberg proustite and erythrite and roselite and uranium-bearing species, Andreasberg pyrargyrite and dyscrasite and fluorite and pink apophyllite, Siegerland malachite and anglesite and millerite and galena, Schwarzwald fluorite and barite and silver, Obermoschel cinnabar and moschellandsbergite
, Ems pyromorphite and cerussite, Johanngeorgenstadt mimetite, Ohrenstock hausmannite, Fichtelgebirge topaz and microcline and herderite, Ehrenfriedersdorf cassiterite and fluorapatite, Ilfeld manganite, Ronneburg whewellite, Hagendorf phosphates .
Associated minerals are tennantite, moschellandsbergite, cinnabar, mercury, perroudite and iltisite (Szakall and Sarp, 2000).
Kolymite occurs as metallic, silvery xenomorphic grains 10-40 [micro]m across, in copper and closely associated with moschellandsbergite.
Moschellandsbergite is rare, found only in the siliceous limonite in the Adolf mine section.
5 mm long, and as thin crusts and coatings, associated with capgarronite, mercury, cinnabar and moschellandsbergite (Szakall and Sarp, 2000).
5 cm in diameter); moschellandsbergite
from Germany (many crystals to 1 cm covering a 7-cm matrix); silver from Michigan (an electric-white arborescent tree 12 cm high); elbaite from Afghanistan (an 8 x 10 x 12 cm blue-pink polished-treestump lookalike on matrix).
