A very old and very rich Czech Tennantite from this historic mining region. The matrix is a sparkling Quartz with several large (for the locality) Siderite rhombs up to 2.5 CM. The Tennantites are in clusters of many small, distinctive crystals, up to 4mm - though most are smaller. The Tennantite masses are relatively bright, lustrous and includes many twins. A small amount of Chalcopyrite is seen with magnification. This can be displayed from several angles that show more Dolomite or more Tennantite depending on preference.
Scheelite on Quartz -classic European

A rarely available habit of Scheelite in balls and masses of tiny crystals on a doubly terminated Quartz. This is a very old specimen from the area also known as Zinnwald (on German side of the border) in the Erzgebirge / Krusne Hory mountains. The Scheelite balls are up to 5mm and composed of masses of small crystals clustered together. With good magnification it can be seen that some of the crystals are elongated pseudo-octahedra. In fine condition the quartz is undamaged and iridescent in person. From an old Czech collection, this is the most esthetic example of this habit I have ever seen.
