Spharosiderite (Siderite)
Estacada Pyrite locality, Clackamas County
Oregon, United States
7.4 x 5.3 x 4.1 CM (cabinet)
price: $280
Late Summer 2021

Sphaerosiderite is a fairly rare form of Siderite usually found in Basaltic flows, and can form in a diverse array of habits. On this piece the red color balls are scattered in an open cavity. A very esthetic specimen in fine condition having great contrast with the cavity lining. Under strong lighting the orange-red Siderites are rather sparkling. These are a lower temperature type of structure that are essentially a microcrystalline rosette form that has a very distinctive habit. Worldwide these have been found as very smooth spheres often with a metallic or smooth luster. The finds in Clackamas County are more often this type of red balls with a textured surface. This is a well-defined and attractive example from this region. Ex Hitchings collection.
