Large blue grey crystals sparkle like the iridescent wings of a tropical butterfly. These are feldspars that formed in a mass of molten rock deep underground. This igneous rock, known as Larvikite, is polished for use as a decorative stone. Larvikite is usually found in sills, where molten rock has intruded into the bedding planes between existing rock layers.
