This gemstone gauge not only measures gemstones from melee to 25mm by 0.01mm, but based on those measurements calculates the weight of a variety of gemstones.
Operation is simple. Just select the type of gemstone and its shape, take the measurements, and the C-Master calculates the weight of diamond, corundum (sapphire, ruby), emerald, and alexandrite stones in round, oval, marquise, square, and cabochon cuts. Its compact size, 7.1" x 0.7", makes it convenient to take with you. The C-Master is made in Japan and operates on a button battery.
