Crystallised native Lead from Långban, Värmlands Län, Sweden. This specimen has been etched out of Calcite or Dolomite - I do not approve of that, but that's how it came to me. |
|
Native Silver crystals from near Batopilas, Chihuahua, Mexico. |
|
These Silver crystals from Kongsberg (Buskerud, Norway) are weird - it is a curved aggregate (no, I didn't 'adjust' it!) of herring-bone Silver. I am sure this has been etched, but check the next one too. |

This is Silver, similar to specimen above, from Kongsberg, Buskerud, Norway. This is guaranteed not etched - yes my vat is itching to get hold of this baby, but no, I will not do it! |

This specimen was given by the Christian VII (1749-1808), King of Denmark and Norway, to Louis XV of France in 1770. Christian VII was later found to be mad - I'd think so! Fortunately the specimen now is in Musée Nationale d'Histoire Naturelle (Paris), who brought it to the TGMS show in 1994. |
| Silver wire growing from the face of a Pyrargyrite crystal from Kongsberg. This was described by Vogt, 1899, in Zeitschrift für praktische Geologie, 7, 113-123, but supposedly all specimens have been lost. Well, one survived. |

Silver 'feathers' to 3 cm on 15 cm Arsenic from Pöhla, Erzgebirge, Sachsen, Germany. Ex coll. Jakob Sokatsch, photographed at Mineralientage München 2003. |

This is truly an unusal specimen, Sulfur crystals on a Calcite matrix, imbedding globules of asfalt from Sicily, Italy. |
|
Native Sulfur crystals on matrix - this specimen is app. 35 cm across - from Mina El Desierto, Cerro Picoloro, Provincia Daniel Campos, Departamento de Potos’, Bolivia. |
|
Sulfur crystals with traces of the imbedding Asfalt from Sicily, Italy. The most complete Sulfur crystals, 'floaters', form in Asfalt and are usually washed out with kerosene. Do not try this at home, etc. Not only is kerosene flammable and stinks, but Sulfur is very susceptible to changes in temperature and pouring a liquid over it may easily crack the crystals. |
