DescriptionFLUORESCENT WILLEMITE AND CALCITE SPHERE
Franklin, New Jersey, USA
The mines of New Jersey's bucolic hills were originally worked for iron, but have become far more famous for producing some of the finest fluorescent mineral specimens in the world. This handsome sphere is composed largely of Calcite, of a lovely soft white and gray tint, attractively streaked with dark veins, and boasting a speckled patch of black Franklinite and brown Willemite. Mildly interesting under normal lighting conditions, it suddenly comes to life under ultraviolet light. Longwave UV rays turn the Willemite a bright green and the Calcite a soft red, but it is under shortwave Ultra-Violet that these minerals really shine: the Willemite still shows a vivid electric green, but the Calcite literally blazes with an incredibly fiery red, dramatically veined with the green Willemite and dotted with black Franklinite. A spectacular and beautiful example of a classic fluorescent conjunction, the sphere measures 5 inches (12.7 cm) in diameter. Offered at no reserve.
