Before i get into Quartz,i first need to add to the glossery! So pls, bear with me . I didn't choose quartz by suggestion of a group member(didn't rec. any) nor on my own! It came from a very beautiful enchanted fey from the land of EF in the form of a question,which i figured the best way to answer this question would to enter the world of Quartz !!!I say world because it is a very large and powerful family,and is used in many ways for many purposes. ENJOY! :)  Mark
