The quartz stone family is extremely large and varied. Rutilated quartz is quartz where a band of foreign mineral has grown inside the quartz. Rutiles may be gold or red (titanium), and sometimes other minerals such as black tourmaline, pyrite, hematite, or epidot (to name a few), may be found growing inside quartz. These types of quartzes with rutiles growing inside them are very rare and sought after. Rutilated quartz is thought to be a powerful healer; it is stronger than other quartz as the rutiles are said to intensify the power for the quartz.
