The user manually places stones in a case that function as a darkroom. After GemPen® is turned on and directed towards a gemstone, a fluorescing effect will occur. By manually analysing this effect, with guidance from the GemPen® Diamond Map and online GemPen®, the user can determine if the stone is a natural diamond or a synthetic diamond.
