This great collection includes a premium, crystal-clear plastic collectors case (measures 8" L X 4" X 1.25" H) and 18 hand-picked rocks and minerals that are each approximately 1 ¼ inches in size. Each rock will differ in size, shape, and color. The included color identification sheet will help you identify the different rocks and minerals. Also comes with Mohl’s hardness scale (an identification tool that rock collectors use for identifying rocks).
Each kit is lovingly and carefully assembled in the USA by our dedicated team in Eugene, Oregon.
