From Sterling Hill, New Jersey, this is one of the most complex pieces from NJ that I have owned and one that changes quite a bit, depending on which wavelength of UV you are using.  7 colors in all, there is blue Hydrozincite, red/orange Calcite, green Willemite, yellow Zincite, creamy Barite, orange Sphalerite, and blue Cleiophane.  The Hydrozincite is visible only on the face shown in the lowest three UV pictures and is most bright under shortwave UV.  The Calcite and Willemite are brightest under shortwave UV also.  The Barite, Zincite, Sphalerite, and Cleiophane are brightest under midwave and longwave UV.  The Barite occurs as clouds and veins while the Zincite occurs as small spots of yellow in the dark areas.  Dimensions are 4 x 2 1/2 x 1 inches.  Weight is 2 lbs 1 oz.  Price: $350
