Green Andradite Crystals from Skjerpemyr, Norway

This attractive small cabinet specimen features well-formed green andradite crystals from the classic Skjerpemyr locality in the Grua mining district near Lunner, Akershus, Norway. The crystals are developed on a natural skarn matrix and display a vitreous to slightly greasy luster.

The clearly visible crystal faces and distinct geometric form give the specimen its particular mineralogical and aesthetic appeal.

Classic Skarn Locality in the Grua Mining District

Skjerpemyr is one of the well-known skarn localities of the Grua mining district. The deposit has a long collecting history and is known for numerous characteristic skarn minerals.

The area has been legally protected as a natural monument since 1984. Mineral collecting and excavation are not permitted there, giving older collection specimens from Skjerpemyr a special connection to the locality.

With dimensions of 5.5 × 4.5 × 2.0 cm and a weight of 50.8 g, this is a compact small cabinet specimen. Its particular appeal lies in the lustrous green andradite crystals, their distinct crystal geometry, and the natural skarn matrix.
