• If the gemstone is too deep and narrow, areas will be
dark, if it is too shallow and wide, parts of the gemstone will be washed out and lifeless.
• Lower quality cuts are easy to spot, because you
can see lighter colors, and ‘Windows’ within the gem.
Windows refer to the ‘Opening of facets’ within the
gemstone, making it difficult for colors to bounce off
the facets within the gem, and allowing light to pass
right through exhibiting little brilliance. Fewer windows
equals more color intensity; the perfect faceted gemstone shows no ‘Windows’ at all.
• Badly angled facets allow light to pass straight
through the gem or to be deviated to the side. Optimum
facets, accurately cut will make light travel back towards
the viewer looking directly into the table facet. The
table facet is the upper most surface of a gem to look
into it you must look directly into the gem from above.
