Lazulite is a shiny mineral with an intense blue color. It is most often found in massive, prismatic or acicular form. Its hardness is 5 to 5.5 on the Mohs scale and it is relatively hard. The main chemical composition is mica hydrosodalite Al2Si5O24 (Na, Ca)2. Lazulite is formed from a combination of alumina and silica. It usually forms at significant depths through dissolution and precipitation processes. It is found in sodium-rich metamorphic rocks, such as serpentine hornfels and serpentine marble, as well as in carbonate shells that are often associated with hydrothermal veins. Lazulite is primarily used as a gemstone, although it is also sometimes used in the alloy and ceramics industry. It is speculated that Lazulite may have healing properties, although there is no scientific evidence to support these claims.

Quartz is a mineral composed of silicon dioxide (SiO2). It is a potent and abundant mineral that forms under a wide variety of conditions, making it very common on Earth. The color of quartz varies depending on the presence of impurities or defective lattices inside the structure, it can be transparent or opaque, colored or colorless. It is highly recognized for its versatility and unique properties, in particular its resistance to abrasion and its transparency (it is optically transparent). The main varieties of quartz are rose quartz, smoky quartz, yellow quartz and citrine quartz. Quartz is formed under diverse geological conditions including sediment deposition, transformation of metamorphic solids, hydrothermal upwelling, and metamorphic contact zone. Quartz is widely used in industry and commerce. It is used to manufacture glass, precious stones, abrasives, sandpaper, glass capsules for the protection of pharmaceutical preparations, jewellery, quartz glasses, molds and tools for cutting metal. It is also used for some optical applications, such as fiber optic lenses and filters.
