Youngite refers to a variety of druzy quartz-coated, brecciated agate from one specific location in Wyoming. This mineral is widely sought after due to its phenomenal and chaotic smattering of colors. It forms via brecciation, a process in which rock fragments are cemented together as silica-rich waters form quartz around them. This accounts for youngite’s variety of colors, including reddish-brown, sky blue, white, peach, and yellow-gold. This mineral is also extremely fluorescent under shortwave UV lighting: it will glow fantastic acid-green color! In the raw, youngite is spectacular to behold, with its odd shapes and druzy quartz crust. This variety of agate truly shines, however, when you cut it into slabs: the wild brecciated patterns create a spectacle with it alien glow under UV light.
