Cut
If it
is not cut right, a flawless D color diamond might be considered
a reject by a diamond dealer. A poor cut can make a diamond
look dull, glassy, bulky, and too small for its weight. A
good cut can increase its brilliance, sparkle, durability,
and aesthetic appeal.
The
term cut is sometimes confusing because it has a variety of
meanings. Jewelers use o [o refer to:
id because he ,)or diamond.
# The shape of a gemstone (e.g. round or oval)
* The cutting style (e.g. brilliant or step cut, single or
full cut)
# The proportions of a stone (e.g. big or small table facet,
deep or shallow pavilion)
~ The finish of a stone (e.g. polishing marks or smooth flawless
surface, misshapen or symmetrical facets)
The proportions
and finish are also called the make of the stone and will
be the focus of this chapter. Shape and cutting style were
discussed in chapter three.
What
is a Poorly Cut Diamond?
Gem experts
can agree on what colors and clarity of diamonds will command
the highest prices, but if you were to ask them what the most
ideal and valuable way to cut a diamond was, you would get
a variety of answers. However, you could get them to agree
that a diamond is poorly cut if the following characteristics
can be noted with the naked eye:
A white
circle resembling a skinny donut in the face-up view of a
diamond In the trade, this is called a fish-eye diamond, and
it is the result of the reflection of the girdle when the
pavilion (the bottom cone-shaped portion of the diamond) is
too shallow.
The thicker
and more prominent the white circle the poorer the cut is.
Besides looking bad, fish-eye diamonds usually lack the brilliance
of well-cut diamonds.
