Yooperlite is a unique and captivating gemstone found primarily in Michigan's Upper Peninsula. It appears as a dull gray or tan rock in daylight, but under UV light, it fluoresces a bright, vibrant orange or yellow due to the presence of sodalite. Chemically, it is a syenite rock rich in fluorescent sodalite, with a Mohs hardness of 5.5 to 6.
