The cut of the diamond is the most important and perhaps the most misunderstood
and controversial of the 4Cs. Diamond dealers refer to cut as make, and it is
the only feature of a diamond that can be controlled by man. The craftsmen at
Whiteflash ensure that every
'Whiteflash ACA' (ACA) Hearts & Arrows
diamond attains the height of beauty and workmanship and therefore, sells only
perfectly cut round brilliant diamond.
Precision cutting is required to maximize the true brilliance of a diamond. When
we talk about cut, we are referring to much more than just the shape of a
diamond. We are talking about the exact angles, proportions, symmetry, and
polish that affect the way a diamond reflects light. In the case of
'Whiteflash ACA' (ACA) Hearts & Arrows diamonds,
precision is of the essence. For maximum brilliance to occur, there
should be absolute symmetry in the placing of the facets and the highest
quality of polishing. The term Ideal Cut does not only refer to proportions but
as much to symmetry and polish. When the proportions are ideal the brilliance,
scintillation and dispersion of light is maximized.
If you ever have the opportunity to visit and witness the cutting procedure of a
hearts and arrows diamond, you would be amazed by the skill of the craftsmen.
Each craftsman checks his work every 15 seconds or more to ensure he remains
within the tight tolerances allowed for Hearts & Arrows diamonds.
Ideal Cut
An accurately proportioned stone will attract the highest price per carat. When
the diamond is cut to gain weight, or spread to make it look larger than it is,
it will be too deep or too shallow.
The ideal cut diamond is cut with such precision that light entering the diamond
reflects internally from facet to facet and is reflected back only through the
top, creating optimum brilliance. If a diamond is not cut to ideal proportions,
the light entering the diamond from the top will disperse through the sides and
bottom of the stone, and the diamond will appear watery, glassy and dark -
without sparkle or fire - regardless of its color or clarity.
60/60 Fallacy
Many of you have probably heard the term "a 60/60 diamond". In case you have
not, this is when a diamond has a 60% table and a 60% depth. This portrays an
image of total balance, implying a fine make. In fact this is a fallacy - the
relationship between the crown and the pavilion of the diamond must be
correctly balanced. According to the American Gem Society - AGS, in order for a
diamond to qualify with ideal proportions the table must be 53-57% and the
depth must range for 60-62.8%
