| The cut is the human contribution to a diamonds beauty. The cut of a diamond effects
the other C's because it determines the finished weight of the stone, it can enhance
the color & also help to hide inclusions. Cutters have studied & experimented
for hundreds of years to bring out the best in a diamond. Diamond cutters over
the years have developed very precise facets & angles to obtain the best optical
effects. These optical effects include the brilliance & fire(dispersion).
Unfortunately, when a cutter studies a piece of diamond rough to be cut, he cannot
just think in terms of beauty. He must balance optimal weight retention with beauty
to produce the most valuable combination. This does not always produce the perfectly
cut diamond.
The cut refers to two terms; Style & Make.
The style can refer to the shape of the stone, the facet arrangement,
or both. The cuts like pear-shape & marquise would fall under this category.
Also, the term brilliant or step cut would also. For example, a round brilliant
diamond is explaining the style of cut.
The make differs from style in that it refers to the proportions
& finish. This is where the true value of cut is played out. It is possible
to have a round brilliant cut diamond (style) with a poor polish & incorrect
proportions(make).
As demonstrated in the diagram below, a diamond has three parts: Crown,
Girdle, & Pavilion.
The pavilion is a diamonds mirrors, reflecting the light entering
a diamond back out through the top. The angle of this mirror is extremely important.
If not correct you can lose alot of brilliance & fire. (See Below)
The crown is the place where the white light is broken into
its spectral hues. Think of it this way, the larger the table, the more brilliance
(white light coming from the stone). The smaller the table & hince larger
the upper girdle, bezel, & star facets, the more dispersion (fire) you will
get through the top of the stone. The balance of these two factors are important
to diamond cutters in creating the most beautiful stone possible.
 The girdle is the center of the diamond where the pavilion
& crown meet. Thickening this area is the easiest way to add weight to a
diamond. Make sure the girdle thickness is in proportion with the rest of the
stone.
The cut of the diamond is the single most important aspect to make sure you
not only getting a diamond with great beauty but also the right price. Think
of it this way, when a cutter adds weight to a diamond by sacrificing the maximum
beauty, what is he doing? He is adding weight to a diamond & giving you
in return, less visual benefit. Diamonds are sold by weight, so what happens?
You end up paying for that extra weight, without getting any benefit in size
or beauty.
For example, if you buy a one-carat diamond that measures 6.5mm in diameter,
you have the look & the weight that you paid for. But if you buy a one-carat
diamond that measures 6.3mm in diameter, you have bought the look of a 0.85-carat
diamond. Why pay for the extra weight if it still looks like a smaller stone?
This is the carat weight trap. Don't be caught. You would be much better off
buying a correctly cut (good make) 0.85ct diamond that measured what it weighed,
than buying the poorly cut (bad make) 1.00ct diamond that looked the same size.
At Jalin Jewelers, we stock all shapes & sizes, but only the finest makes.
The Ideal Cut Diamond describes a round brilliant diamond that has been cut
to exact and mathematically proven proportions. Its symmetry, with 58 exactly
placed facets, produces the ultimate in lustre and beauty.
When a diamond is cut to the ideal proportions, all of the light entering from
any direction is totally reflected through the top and is dispersed into a display
of sparkling flashes and rainbow colors.
 A Premium Cut Diamond
demonstrates subtle variations from the Ideal Cut. Although dimensional differences
affect a diamond's reflection of light, a Premium Cut still achieves a harmonious
balance between it's proportions and the display of brilliance.
