Diamond Cut - How Does Yours Shape Up?
By
Gail Leino
When one hears of diamond cut they usually think of the
different kinds of diamond shapes they've seen in jewelry, the
princess, the round and so on. In the world of diamond grading
diamond cut refers to something else. It refers to how well a
jeweler has cut the diamond to achieve maximum carat size and
brilliance, or the millions of glittering sparkles you can see
when you turn your diamond in the light. Poorly cut diamonds
will often sell at a cheaper rate than the better cut.
Interestingly ninety five percent of diamonds aren't cut for
optimum brilliance. There are four factors involved in the
diamond cut, proportion, finish, symmetry and polish.
The proportions of the cut have to do with the table
percentage compared to the depth percentage. The table is the
flat surface on the top of each kind of diamond cut, while the
depth has to do with the width of the diamond from top to
bottom. A good table to depth ratio will allow all light
entering the diamond to be reflected back through the surface.
The symmetry of a diamond is how well the facets of a diamond
match up. If the facets don't match then light entering the
diamond will leak out the sides and not be properly reflected to
the surface. The classifications of symmetry are the same as for
polish.
The polish of a diamond refers to how finely polished the
surface is to make it very reflective. Diamonds are the hardest
materials on earth and they must be polished using diamond grit,
so the process is time consuming. The grades for polish range
from Ideal to Excellent, Very good, Good, Poor and Fair.
A diamond's finish is made up of the individual diamonds
polish and symmetry. If a finish is very good then the polish
and symmetry's of the diamond were very good, excellent, or
ideal.
