Yooperlite Bracelets (10mm)

Yooperlite is a type of fluorescent rock found primarily in Michigan's Upper Peninsula (hence the name "Yooper" from "U.P."). It gained popularity due to its unique property of fluorescing under ultraviolet (UV) light. Here's more about Yooperlite:

Characteristics

• Color: Yooperlite appears as a grayish or brownish rock under normal light. However, when exposed to UV light (specifically longwave UV light), it exhibits a vibrant fluorescent glow, typically in shades of yellow, green, or orange. This fluorescence is caused by the presence of minerals such as sodalite and fluorescent minerals like fluorescent calcite or fluorescent gypsum.
• Composition: Yooperlite is often composed of various minerals, including feldspar, quartz, and minerals that contribute to its fluorescence.
• Location: Yooperlite is primarily found along the shores of Lake Superior in Michigan's Upper Peninsula. The rocks are often discovered on beaches or in areas where erosion exposes the minerals.
• Collecting: Due to its unique fluorescence and geological origin, Yooperlite has become a sought-after collectible for rockhounds and enthusiasts of fluorescent minerals.

Uses and Display

• Collectibles: Many people collect Yooperlite specimens for their fluorescence and unique appearance. Some collectors may polish and display Yooperlite rocks or use them in artistic and decorative projects.
• Lapidary Art: Yooperlite can be cut and polished to reveal its fluorescence and enhance its visual appeal. This is often done by lapidary artists who work with fluorescent minerals.
• Educational Purposes: Yooperlite is also used in educational settings to demonstrate fluorescence and the properties of minerals under UV light.

Care and Handling

• UV Light: When viewing Yooperlite under UV light, use caution and appropriate eye protection as UV light can be harmful to the eyes.
• Cleaning: Clean Yooperlite rocks gently with mild soap and water. Avoid using harsh chemicals or abrasive cleaners that could damage the rock's surface or fluorescence.
• Display: Display Yooperlite in a location where it can be viewed under UV light to showcase its fluorescent properties. Avoid prolonged exposure to direct sunlight, as this can cause fading of the fluorescence over time.

Yooperlite's fluorescent glow under UV light makes it a fascinating and visually striking rock specimen. Whether collected for its unique properties, used in lapidary art, or displayed for educational purposes, Yooperlite captures the curiosity and fascination of those interested in geology and fluorescent minerals.
