What Makes Yooperlite So Special? Origin and Mineralogical Properties

Yooperlite is the popular trade name for syenitic rocks from Michigan's Upper Peninsula (the so-called "Yoopers"), which are rich in fluorescent sodalite. This mineral was only discovered in 2017 by Erik Rintamaki on the shore of Lake Superior – since then it has been considered one of the most exciting mineral discoveries of recent times. Under shortwave UV light (365 nm), the sodalite inclusions glow in bright orange and yellow, while the piece appears plain gray in daylight. This optical phenomenon is called fluorescence and is based on the excitation of certain structures within the sodalite by UV radiation.

Care and Handling of Yooperlite

The raw natural specimens are robust and easy to care for. For cleaning, clear, lukewarm water and a soft cloth are sufficient. Strong cleaning agents or ultrasonic devices should be avoided, as they can damage the natural surface. To fully reveal the fluorescent glow effect, a UV lamp with a wavelength of 365 nm is recommended – standard blacklight lamps with 365 nm are available from specialty retailers. Store the pieces away from light to permanently preserve the natural surface.
