The color of the quartz

The crystal-gazer’s trance can be induced with any shiny object, including a crystaline gem stone. The size of quarty preferred varies greatly among those who practice crystallomancy. Some gazers use a few inches diameter quarty that is held in the hand; others prefer a larger quarty mounted on a stand — although most authors agree that the expense of a very large quatz is not always justified by added efficacy. The stereotypical image of a gypsy woman wearing a headscarf and telling fortunes for her clients by means of a very large crystal ball is widely depicted in the media and can be found in hundreds of popular books, advertising pages, and films of the 19th, 20th, and 21st centuries, and the pervasiveness of this image may have led to the increased use of fairly large crystal balls by those who can afford them.
