Larvikite

 Larvikite is primarily found in the Larvik region of Norway, from which it derives its name. It's also referred to as Norwegian Pearl Granite or Blue Pearl Granite. Larvikite is formed from the slow cooling of magma, which allows large crystals to develop. It is part of the monzonite family, specifically a variety of monzonite known as monzodiorite. Due to its attractive blue and silver flash (schiller effect), larvikite is often used in cabochons, beads, and other jewelry components. The schiller effect is caused by the presence of feldspar crystals, which reflect light in a captivating way. In the metaphysical community, larvikite is believed to enhance psychic abilities, increase intellect, stimulate creativity, and provide protection. It is also thought to ground and stabilize emotions and energies. Larvikite has a Mohs hardness of about 6 to 6.5. This makes it relatively hard and suitable for various applications, including jewelry and architectural uses.
