Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.

Tumbled quartz crystals typically have a glassy luster and a conchoidal fracture. This means that when they break, they produce curved surfaces like the inside of a seashell. Quartz crystals have a hardness of 7 on the Mohs scale, meaning they are harder than steel but softer than diamond.

Quartz crystal tumbled stones are also used in crystal healing. Crystal healers believe that quartz crystals have a variety of healing properties, such as, amplifying energy, balancing the chakras, promoting healing and well-being, reducing stress and anxiety, improving mental clarity, boosting the immune system.
