Collection: Yooperlite

Yooperlite stone is a fascinating rock that has gained popularity in recent years, particularly for its amazing visual properties.

🌌 What is Yooperlite?

Yooperlite is actually a syenitic rock rich in sodalite , a fluorescent mineral. What makes it special is that the sodalite in the stone glows a bright orange light when exposed to ultraviolet (UV) light , such as from a portable UV lamp.

📍 Origin of the name

The name "Yooperlite" comes from the term "Yooper" , which refers to the inhabitants of the Upper Peninsula of Michigan (UP), in the United States. The suffix "-lite" refers to a rock or mineral. The stone was discovered and named in 2017 by Erik Rintamaki , an amateur rock hunter.

🌍 Where can we find it?

Yooperlites have been discovered primarily along the shores of Lake Superior in northern Michigan, USA. However, similar rocks containing fluorescent sodalite can be found elsewhere, including Canada and Finland .

✨ Features

  • Color in natural light : gray, bluish or blackish, often grainy.

  • Reaction to UV light : orange or yellow shiny parts due to sodalite.

  • Composition : syenite (igneous rock), with fluorescent sodalite .

🔮 Use and symbolism

In 2018, Erik Rintamaki, mineral enthusiast and merchant, walked on a beach on Lake Superior, near Michigan in the United States and discovered three small fluorescent pebbles.

For the record, fluorescence is a property possessed by certain minerals "to absorb light and re-emit it in the form of radiation of longer wavelength. We distinguish between fluorescence which stops as soon as illumination ceases, from phosphorescence, which persists”.

Curious, he then decided to send the stones of his discovery to the university organization Michigan Tech. He identified them as being clasts (fragments of mineral or organic origin forming part of the composition of a rock) of syenite containing fluorescent sodalite. This unique mineral variety has not been previously identified. These stones were named “yooperlite” because of the nickname “yooper” given to residents of the Upper Peninsula of Michigan.
