Introduction

This Yooperlite egg is a striking geological statement piece that combines a rugged, natural appearance with an unexpected transformation under ultraviolet light. In normal lighting, it presents as a dark, speckled stone with earthy grey, brown, and black tones. Under UV light, however, it reveals vivid orange fluorescence—an effect that never fails to surprise.

Standing approximately 5 inches tall and weighing around 1 kilogram, this egg has substantial presence. It works equally well as a conversation-starting display piece or as a collector specimen with genuine geological interest.

Geological Overview

Yooperlite is the trade name for a sodalite-bearing syenite, an igneous rock composed primarily of feldspar with fluorescent sodalite inclusions. It belongs to the igneous rock class, rather than being a single mineral species.

The orange fluorescence seen under UV light is caused by sodalite within the rock matrix. These inclusions were discovered along the shores of the Great Lakes region and brought widespread attention to Yooperlite due to their dramatic response under ultraviolet light.

Aesthetic Appeal

In daylight, this egg displays a dense, mottled pattern of dark greys, blacks, and muted earthy tones, polished to a smooth finish that highlights its natural texture. The form feels solid and grounded, with subtle visual movement across the surface.

Under UV light, bright orange fluorescence appears across the stone, revealing hidden sodalite patches and dramatically changing the stone’s character. This dual personality is a key part of Yooperlite’s appeal.

Metaphysical Properties

Yooperlite is often associated with truth, self-expression, and inner awareness, reflecting its ability to reveal what is hidden beneath the surface. Many people work with it as a stone of insight and emotional clarity.

In egg form, Yooperlite symbolically represents potential and discovery—the idea that more exists beneath the surface than is immediately visible.

Rarity & Collectibility

Yooperlite is geographically limited and relatively recent in the mineral marketplace, making large polished eggs of this size far less common than smaller stones. Specimens with strong, even UV fluorescence are particularly desirable among collectors.

Collector’s & Display Notes

This egg displays beautifully on a sturdy stand in ambient light and becomes a true centerpiece when paired with a UV flashlight. It is ideal for shelves, desks, or educational displays where its fluorescence can be demonstrated.

As an igneous rock, Yooperlite is durable and suitable for long-term display.

Condition & Authenticity

All-natural Yooperlite with no dyes, repairs, or artificial enhancements. Natural surface texture and internal variation are consistent with igneous rock formation and should be considered part of the specimen’s character.
