Young collectors will be fascinated by all there is to know about rocks and about classifying - sorting and organizing objects by attributes like color, shape, or size. Grab your rock hammer and join the fun with this entertaining story by Stuart J. Murphy and lively art by Cat Bowman Smith.

Heavy duty wide Hard Cap minimizes chips from flying off the chisel head and provides a wider head to help protect the hands from missed blows. Even has a centering target!

The BelOMO 10x21mm(.85") triplet loupe magnifier has a viewing area of 0.65 inch (17mm), much larger than the Bausch & Lomb Hastings Triplet Magnifier. The 3 elements making up this achromatic triplet provide a bright and clear view. The 10x power magnification provides the best magnification to depth of field ratio and is the most popular power for a hand held magnifier. The housing and cover are machined metal and coated with a matte black finish and assembled using flathead screws. Belorussian Optical and Mechanical Association (BelOMA), makers of sights for guided weaponry, camera lenses, and other optical components manufacturers these loupes.
We highly recommend this loupe. This is the lens we use all the time.
Each BelOMO loupe we ship is custom treated to prevent the screws from coming loose with usage.
