In ancient times, various cultures believed that quartz was a form of petrified ice. Quartz is the most abundant and varied of all minerals on earth – in fact there are many gemstones that are actually varieties of quartz, including amethyst, citrine, onyx, agate, and chalcedony. Because of the clarity of crystals, their relative hardness and their large availability, quartz is an excellent alternative to more expensive gemstones.

Quartz is said to be an extremely powerful gemstone metaphysically, and is thought to bring protection and healing to the wearer, along with promoting clarity and purity of spirit and body.


Pure quartz is clear and colorless but it is also found in a vast array of colors, from palest pink to richest black. Pink and smoky (brown) quartz are among the most popular colors.

Gem Family

Quartz is a gem family unto itself.


Quartz has a hardness rating of 6.5‐7.0 on the Mohs scale, making it suitable for everyday wear.


Irradiation treatment is used to enhance the color of smoky quartz. Heat treatment is used to lighten the color of darker quartz.


Like most gemstones, quartz should be stored separately to keep from scratching or being scratched. Store them in a lined box or a soft pouch. Avoid steam or ultrasonic cleaners, and keep your quartz sparkling by cleaning it under warm running water with a mild soap. Dry with a soft, lint‐free cloth.
