Polish
influences how well light is able to pass
through a diamond and is very important
to a diamond's brilliance. It is necessary
to select a diamond that is laboratory certified
with good, very good or excellent polish.
Diamonds that have poor to extremely poor
polish are less brilliant because they have
microscopic polish lines that blur the surface
of the diamond. These polish lines reduce
the amount of light that enters or exits
a diamond. When selecting your diamond be
aware many diamonds possess poor polish.
Diamond cutters can greatly reduce labor
costs by not taking time to properly polish
a diamond.
