To assure our customers of the exact grading specifications that we quote,
diamonds above 1.00 carats will be accompanied by the following:

Making Nash Jewelry your first choice for diamonds will eliminate any and all
uncertainty about the quality of the diamonds you buy. Our high tech approach to
grading and certifying diamonds makes us a clear leader in today's diamond
The 4 C's
1. Cut: A diamonds shape also plays an important role and often
affects how much sparkle it displays. Round shapes possess the most
brilliance. Marquise, Pear, Princess, Radiant, and Emerald cuts are very
elegant and also possess great fire.
Cut is sometimes not discussed by certain jewelers because it requires
academic mastery of the topic and the sincerity to convey an accurate
description of a fine diamond. With all of its other characteristics equal,
a poorly cut diamond does not look as good and is tremendously less valuable
than a well-cut diamond. You might pay less for a poorly cut diamond, but
the diamond will always be esthetically inferior. With all the other
characteristics equal, the value of a well-cut diamond is much greater than
that of a poorly cut diamond. Nash Jewelry sells only well-cut diamonds and
stresses the importance of getting the best value, for the best diamond.
2. Color: The word color brings to mind bold, vivid images, but when
used in regard to diamonds, the meaning is quite the opposite. The most
sought after diamond is actually referred to as colorless. Diamonds range in
color from colorless to yellow. There are also fancy color diamonds that are
highly sought after such as pinks, Canary yellows and blues. These are
extremely rare and can be quite expensive.
The following is the G.I.A. grading system standard for diamond color:
Grade D, E, F: Colorless
Also know as Fine White or River White. This diamond color is the finest and
Grade G, H, I, J: Near Colorless.
Known also as White. Experts sometimes find them hard to distinguish from
Colorless when they're set. They're truly an excellent value choice.
Grade K, L, M: Faint: Yellow
Referred to as Top Silver, these diamonds have a yellow tinge and are more
Grade M, N, O, P, Q, R: Very Light Yellow
Grade S-Z: Light Yellow
Even though you may not be able to see the almost imperceptible letter grade
distinctions between colorless and neat colorless, or one or two letter
grades of tints, by buying a diamond with G.I.A. Certification, you are
guaranteed the certainty of it's quality.
3. Clarity: Unseen by the naked eye, a diamond's landscape and true
characteristics are revealed when the diamond is viewed under a jeweler's
microscope or loupe. Within this miniature landscape of unique and natural
occurrences, there are tiny specks, ripples and indentations embedded in the
crystal, which identify your diamond much like a fingerprint. These
imperfections are known as inclusions, and the degree to which a diamond is
free from them determines the clarity and value of the gem.
The clarity scale is broken down into the following grades:
Free from all inclusions or blemishes.
IF: Internally Flawless
No inclusions visible at 10x magnification.
VVS1: Very Very Small Inclusion 1
Inclusions that are extremely difficult to locate at 10x.
VVS2: Very Very Small Inclusion 2
Inclusions that are very difficult to locate at 10x.
VS1: Very Small Inclusion 1
Minor inclusions that are difficult to locate at 10x.
VS2: Very Small Inclusion 2
Minor inclusions that are somewhat difficult to locate at 10x.
SI1: Small Inclusion 1
Noticeable inclusions that are easy to locate at 10x.
SI2: Small Inclusion 2
Noticeable inclusions that are very easy to locate at 10x. Some inclusions
may be seen with the unaided eye.
I1: Included 1
Obvious inclusions. Somewhat easy to locate with the unaided eye.
I2: Included 2
Obvious inclusions. Easy to locate with the unaided eye.
I3: Included 3
Obvious inclusions. Very easy to locate with the unaided eye.
The above clarity grading scheme is in accordance with the GIA
(Gemological Institute of America) .
4. Carat: Carat is the unit of weight for diamonds. Diamonds under
one carat weight are discussed in terms of "points" - with 100 pints equal
to one carat. A stone weighing 75 points weighs 75/100 of a carat, or 3/4
carat; a 25 point stone is 1/4 carat; a 10 pint stone is 1/10 carat.
Knowing the "per carat cost" will allow you to know the actual diamond
price. In pricing, there's a great difference between one carat total weight
verses the weight of one stone (1 ct). For example, a one carat diamond is
much more valuable and much more expensive than a grouping of several
smaller diamonds which when combined, add up to one carat in total weight.
The G.I.A.-Gemological Institute of America was established to provide
universal grading systems and accurate, indispensable information for the
entire jewelry industry. It has become the hallmark of reliability and the
indicator of integrity. Known and respected G.I.A. Gem Trade laboratories
issue a diamond grading report. This report provides great details on the
diamond and offers a diagram of internal and external characteristics or
flaws. It is the fingerprint that uniquely identifies that particular
diamond and which could be used later to verify that diamond. Because G.I.A.
grades only natural diamonds, those who purchase diamonds with a G.I.A.
Diamond Grading Report will be assured that their diamond
will not be a synthetic (man-made) or clarity enhanced
(fractured filled) diamond. These are the prevalent problems facing the
consumer in this high-tech era.
Clarity enhanced diamonds will not be awarded a G.I.A. report simply because
clarity enhancement involves the filling of extremely poor quality diamonds
with polymers to improve their appearance. This is a reversible chemical
process that usually involves diamonds that are classified below G.I.A.'s
lowest clarity rating 13.
Even though the diamond is the hardest material known to man, it is not the
toughest. When subjected to substantial mechanical stress it can be damaged.
Therefore it is wise not to wear the diamond ring when involved in
activities that are physically rigorous. Always take out adequate but not
excessive insurance coverage on the ring. The key to cleaning the diamond's
smooth hard surface is to remove the grease and skin oils it attracts. Warm
water, grain alcohol or ammonia can be used with a soft brush. Diamonds can
scratch anything including each other, so store them in velvet compartments
separate from other precious gems or delicate jewelry. If this is an
engagement ring, take care that the prongs of the setting remain secure by
checking them carefully after each cleaning.
