The GI-7201 darkfield loupe is a small instrument that provides 10x magnification as in a standard loupe, with an important added feature: it is combined with a specially constructed area that enables you to view a gem against a black background with strong lateral lighting. This is called darkfield illumination, the reason why this instrument is called a darkfield loupe.This type of lighting environment makes it easier to see certain types more precisely what they are. Especially valuable for colored gemstone buyers because seeing inclusions clearly plays an important role in separating one colored stone from another.The darkfield loupe is an important and essential tool in examining colored gemstones, for anyone buying diamonds or diamond jewelry and in viewing many fracture-filled diamonds that are currently circulated worldwide. A fracture-filled diamond also known as clarity enhanced diamond, is a diamond which contains a crack or cracks that have been filled with a glass-like substance to improve the overall appearance of the stone. Using the darkfield loupe is the easiest way for most people to spot fracture-filled diamonds.
