Named after Larvik, Norway, where this rock is found, is also referred to as blue pearl granite. It is a variety of monzonite with large inclusions of feldspar. When polished, the feldspar creates the silver blue sheen, known as the schiller effect. It is usually dark greyish blue with steel coloured flashes. Used by some as a protective stone, it is said to be grounding with a strong connection to the earth and spirits of nature.
