Dendritic Pyrargyrite in Matrix
Dendritic Pyrargyrite in Matrix from St Andreasberg, St Andreasberg District, Harz Mts, Lower Saxony, Germany
Collection Robert Lavinsky
Description There are classic old mineral specimens that predate the 20th century. Then there are the true old-timer specimens that predate the 19th century, like this Pyrargyrite from the Ferguson Collection, circa 1800 (he had stopped collecting by 1810, it is thought). Dendritic crystals of lustrous, black Pyrargyrite to 5.0 cm in length are emplaced the length of a flat gray limestone matrix. Even the back side is interesting with a mass of spongy, dark gray Silver and ore. When historically important specimens, like this from St. Andreasberg in the Harz Mountains, are also visually important, a pretty specimen becomes significant beyond its eye appeal. This is a piece that is much better in person, and impresses even those who do not collect the silver species. The crystals have a slight red overtone, and definite luster to them. This collection came to light in London, when it resurfaced from the family's estate after being passed through the generations largely untouched. Ed David originally acquired the piece from Herb Obodda when Herb got back with specimens from this collection. Ex. Dr. Edward David Collection.
