Detail information of products

The
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.
