Wonderful set duo spheres of Quartz crystal and White crystal on a custom stand. Quartz is one of the most abundant minerals on Earth and comes in many varieties with various colors and crystal forms. It is a hard and durable mineral composed of silicon and oxygen atoms. It has a hexagonal crystal structure and is commonly found in the form of hexagonal prisms with a pointed tip. A white crystal typically consists of minerals such as quartz, calcite, gypsum, or halite. These minerals form crystals—solid materials whose atoms are arranged in an orderly repeating pattern. The white color often comes from tiny air bubbles, impurities, or internal fractures that scatter light within the crystal.
