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.
