There is a video that has been mentioned here a couple of times (Re: Kiesha Crowther - "Little Grandmother"):
Crystal Message: http://www.vimeo.com/18090033
"This video is in response to Little Grandmother's urgent message on the wearing of crystals to unite her community of followers. The photographs contained in this video are from various quartz mines around the globe, including those that consider themselves to be environmentally, ethically and morally responsible.
"To others who use crystals for spiritual and aesthetic purposes, please pay attention "
