This tripod loupe is perfect for hands free viewing of any loose melee stones in your shop.  The lens has a nearly 16 millimeter diameter and features 10x magnification.  While you can use the tripod base for hands free viewing, the loupe can be removed from the base if needed.   To use, simply hold the stone under the tripod to inspect any inclusions or surface marks, or for easy magnification.  Order today at Stuller.com/tools.
