I believe it is a classic adventure fantasy. The protagonist is a teenaged boy with a bow and arrow and long hair. There is a girl, of course, and I think there is an evil witch, but I may be wrong on that one. The crystals, I think, are magical or may even be used as energy weapons, and, I'm not sure about this, the crystals may even grow all over the landscape. The series is from the 90's to the early 2000's.
Any help would be appreciated. Thanks.
