Here’s a cool item, a polished piece of South Dakota Chalcedony. This cool specimen has good color, a nice design, will fluoresce a brilliant green color under a SW/LW light and a nicely polished face with balance left natural.  It measures 9 1/2” x 3 3/8” x 3 1/8″ thick.  The specimen was handcrafted in our very own lapidary department.  Definitely a one-of-a-kind treasure or makes a great gift!
