Larvikite is a type of igneous rock, specifically a variety of syenite, known for its striking appearance. It is primarily composed of feldspar, with a unique blue-gray color and shimmering crystals that reflect light. This mineral is often used in construction and decorative applications due to its durability and aesthetic appeal. Originating from the Larvik region in Norway, larvikite is sometimes referred to as "Norwegian moonstone" because of its visual similarities to the gemstone. It is popular in countertops, tiles, and monuments, making it a sought-after material in both residential and commercial projects.
