This skull is carved from Yooperlite, a type of syenite rock that contains fluorescent sodalite. Under normal light, Yooperlite appears gray to dark stone-like, but when exposed to ultraviolet (UV) light, the sodalite inclusions fluoresce bright orange-yellow, creating a striking glow.
Details:
- Material: Yooperlite (syenite with fluorescent sodalite)
- Size: Approximately 3 × 4 inches
- Appearance: Polished skull with a gray to dark base color; bright orange-yellow fluorescence under UV light
- Formation: Formed from igneous processes; sodalite inclusions within syenite give Yooperlite its unique fluorescent properties
- Physical Properties: Mohs hardness 5.5–6; smooth polished surface; UV-reactive fluorescence
- Educational Value: Demonstrates fluorescence in minerals, the presence of sodalite in igneous rocks, and how UV light reveals hidden features
This Yooperlite skull offers both a striking decorative carving and a fascinating example of mineral fluorescence.
