The seventh installment of Thumbnail Thursday is a nice cluster of yellow and purple Fluorite cubes from Cave in Rock, Illinois. Aside from the obvious aesthetics of this piece, what makes it interesting is that it arrived in an original Perkins Perky Box and the label on the bottom is dated 1981 with a 25 cent price tag. Imagine a specimen this nice selling for a quarter
A thumbnail sized specimen is generally regarded as one that's between 25mm and 35mm and can fit inside a standard sized, 1.25" Perky box. I sell a variety of perky box products here at perkyboxes.com. I also sell filtered UV flashlights here.
