Hunt for the gemstones and fossils that become fluorescent when illuminated with ultraviolet light in a dark room. This 20 pound bag contains a large variety of minerals with some that glow in the dark. This bag comes with a 9 LED 385 Nm flashlight that requires 3 AAA batteries not included. The picture shows some of the fluorescent minerals lit with the enclosed flashlight as well as what they look like with regular lighting. Have fun! This is a cool bag!
