Larvikite points collection box with 2-2.3 kilos of natural Larvikite points from Norway.

Larvikite is an igneous rock rich in plagioclase, mainly in flaky form. This produces a characteristic blue-gray sheen and a 'shiny' appearance when polished, which is not caused by mica. Larvikiet, named after the Norwegian town of Larvik where it was first described, is known for its origins in the region around Oslo in southern Norway. This area contains a complex of magmatic rocks, mainly monzonite. The volcanism that formed this complex has been dated to the Early Permian (297 - 292 Ma) using the U-Pb method. The magmatic activity is thought to be associated with the opening of the current North Sea, a rift basin that did not lead to ocean formation, known as a 'failed rift'. Due to its shiny properties in polished form, larvikite is often used as a natural stone for store facades, counter tops and other decorative purposes.
