The quartz stone family is extremely large and varied. Some of the more famous members include amethyst (purple quartz), citrine (yellow quartz), rose quartz (pink), smoky quartz (black), rutilated quartz (quartzes with other minerals growing inside them), as well as all the various agates and jaspers. Quartz may be found worldwide including many Canadian locations.

Hematite or hematoid quartz is an unusual stone which can range from various tones of yellows and reds depending on the iron content in the quartz. This occurs very rarely in nature. Sometimes other minerals may occur within the quartz, these stones are called lodalite quartz. The dots and various metals, rutiles, and inclusions make for very interesting stones, no two are alike. They are prized by collectors.
