Upon first glance, this cabinet piece looks like a large chunk of granite. However, when viewed under a shortwave UV light, one can see that it is made up of several unusual minerals, such as Hardystonite, willemite, clinohedrite, and franklinite. These minerals are easy to define by their fluorescent colors: Hardystonite makes up most of the material, and shows a dim but pervasive deep violet glow. The willemite occurs in small spots and in thin, straight veins that glow with the standard bright green color, and the clinohedrite is concentrated on only one face, showing a pale orange. The franklinite is distinct through its lack of fluorescence.
