Exceptional Yooperlite Sphere -- 68mm, 426g -- Highly Saturated 360° UV Response For Sale

Adding even more visual interest is a naturally occurring band of material that fluoresces icy white to pale blue under 365 nm UV, providing striking contrast against the vivid orange fluorescence. This unique combination creates exceptional depth and makes the sphere visually engaging both in daylight and under ultraviolet illumination.

In normal lighting, the sphere displays attractive coarse-grained syenite with contrasting black mafic minerals, soft pink feldspar, translucent gray quartz, and subtle violet sodalite, offering classic Yooperlite aesthetics. Under UV, it transforms into an intensely glowing display specimen unlike ordinary decorative spheres.

At 68 mm and 426 g, this substantial sphere has impressive display presence and represents a premium example of one of the most fascinating fluorescent stones discovered in recent years.

The name \"Yooperlite\" was coined after the discovery of fluorescent sodalite-bearing syenite along the shores of Lake Superior in Michigan\'s Upper Peninsula. The term \"Yooper\" is the long-standing nickname for residents of Michigan\'s Upper Peninsula (U.P.), derived from the abbreviation \"U.P.\" Because these remarkable fluorescent stones were first discovered and popularized along the Lake Superior shoreline, the trade name \"Yooperlite\" has become synonymous with these spectacular UV-reactive specimens.
