Quartz is a popular alternative to April's birthstone, Diamond. It is a mineral that contains silicon and oxygen atoms. Aside from feldspar, it is the most abundant and diverse mineral in Earth's crust. Quartz can come in a variety of colors, but most commonly it is known for its crystal clear appearance and naturally faceted formation. It is said to promote stability, allow the release of negative energy, and stimulate the mind to be opened. It is also great for amplifying the healing properties of other stones used with it, it is used widely in meditation and healing, for this very reason. Because Clear Quartz has prismatic ability, it balances all of the chakras, and allows them all to work together in harmony.
