Stone profile
- Family or nature: Trade name for rock pebbles containing fluorescent sodalite
- Colors: Speckled gray in daylight, with orange or yellow fluorescence under UV light
- Symbolic markers: curiosity, discovery and hidden light
Characteristics and origin
The name Yooperlite mainly refers to syenite pebbles rich in fluorescent sodalite discovered around Lake Superior. It is not a new mineral species. Their fluorescence becomes visible under an appropriate ultraviolet lamp and depends on the amount of sodalite present.
Traditional symbolism
In the traditions of lithotherapy and certain cultural practices, this material is associated with the following themes: curiosity, discovery and hidden light. These associations are cultural, spiritual or personal markers. They do not describe an action produced by the stone.
Yooperlite in jewelry
Cut into beads, cabochons or pendants, this rock often retains a discreet gray appearance in normal light. The fluorescent effect requires a UV source and does not mean that the stone emits light on its own.
Care: Clean it with lukewarm water, mild soap and a cloth. Avoid impacts and abrasive products.
