THE 4-Cs
FOR PERFECT DIAMOND SELECTION
A diamond’s cut, color, clarity and carat weight are
used to determine a diamond’s rarity. Any diamond that
includes the highest ratings of these 4-Cs is considered more
rare and more expensive. While considering these important
factors, keep in mind that the 4-Cs will not diminish in value
over time. The following information has been arranged to
illustrate and establish the priority you should place on
each category when considering what characteristics are most
important when purchasing a diamond. The first and foremost
important factor to consider when purchasing a diamond is
cut. Keep in mind, while the internet is a great resource
for information, it is impossible to evaluate the diamonds
cut for brilliance online. Just as Don Basch would never purchase
a diamond without first viewing it, neither should you.
CUT:
• Refers to the angles and proportions of a diamond.
• A master cutter can reveal the stone’s fire
and beauty by using different shapes including round brilliant,
pear, oval, marquise, emerald cut (rectangular), heart and
triangle.
• Cut affects luster, brilliance, dispersion and scintillation,
which determine the diamond’s optical beauty (The way
a diamond reflects and refracts light).
Luster: The quantity and quality of light reflecting from
the surfaces of a diamond.
Brilliance: The amount of white light returned to the eye
from the diamond.
Dispersion: The amount of rainbow colors returned to the eye
from the diamond.
Scintillation: The sparkle, which is the combination of luster,
brilliance and dispersion when there is movement by the wearer
or light source.
• Ideal cut: A diamond cut to optimal proportions, with
optimal polish and symmetry, with the most weight loss to
produce maximum optical beauty. When a diamond is cut to this
standard, it is considered most valuable, with only 5% of
the round brilliant diamonds on the market cut to this standard.
• Well-cut: Diamonds that have very good optical beauty
that fall just outside of the parameters of an ideal-cut diamond.
Well-cut diamonds are priced less than ideal cuts because
they are not as rare.
• Deep cut: A diamond that appears smaller than it weighs
because its weight is retained in the depth. These diamonds
are sometimes called nail heads, due to their dark, face-up
appearance, and are less valuable.
• Shallow cut: Weight is retained in the diameter, making
the diamonds appear larger than they weigh. They are sometimes
called fisheyes, due to unsightly reflections in the crown
area.
• Jubilant Crown patented cut. While not part of the
traditional 4-Cs, the jubilant crown has been recreated
from an original cut made for Queen Victoria. This diamond
has 16 additional facets that create more fire and sparkle
than a traditional round cut and no more expensive than a
well made traditional round brilliant cut. It’s so captivating,
it will leave you breathless!
COLOR:
• Refers to the degree to which a diamond is colorless.
• Although diamonds come in all colors of the rainbow,
the most rare colors include red, pink, green and blue. We
are referring to natural colors and not radiated. It is possible
to create a colored diamond through radiation. Natural colors
are rarer and more expensive.
• When there is an absence of color (colorless) in diamonds,
they are brighter, rarer and therefore cost more.
• Diamonds are graded by color from the Gemological
Institute of America (GIA), which ranges from D (colorless)
to Z (warmest). Warmer colored diamonds (K-Z) are particularly
desirable when set in yellow gold. Icy winter whites (D-J)
look stunning set in white gold or platinum.
CLARITY:
• Refers to the presence of inclusions in a diamond.
• An inclusion in the middle or top of a diamond could
impact the dispersion of light, occasionally making the diamond
less brilliant.
• Although inclusions may not affect the beauty to the
eye, when the diamond is well cut, they do affect the price.
• Inclusions are ranked on a scale of perfection; known
as clarity, which was established by the GIA. The clarity
scale, ranging F (flawless) to I (included), is based on the
visibility of inclusions at a magnification of 10x.
• Laser drilling to remove the inclusions can enhance
a diamond’s clarity.
• Diamonds that have feathers reaching the surface may
be fracture filled to make these feathers less visible. It
is very important to tell your jeweler if you have a clarity
enhanced diamond when leaving for repair. The enhancement
can come out when applying heat for repair. If that happens,
it can be re-enhanced.
CARAT WEIGHT:
• Refers to the weight of a diamond.
• 1 Carat = .2 Gram
• Carat weight usually has the greatest impact on value,
based on rarity.
Looks are deceiving. Cuts and mounting can make a diamond
appear larger or smaller than its actual weight. By letting
your Don Basch Jewelers associate assist and explore all avenues
for you, you can find the right diamond and setting to optimize
the beauty of your stone.
DIAMOND CERTIFICATES / APPRAISALS
Diamond certificates, more accurately known as diamond grading
lab reports may be given with the purchase of any significant
diamond. Items such as diamond engagement rings, may have
a lab certificate for the center diamond only, but most definitely
will receive an appraisal for the entire value of an item
which will be used for insurance purposes. Lab reports increase
the cost of the diamond a minimum of $250 or more, depending
on the size of the diamond. Lab reports are provided and prepared
by an independent, certified gemologist. These certificates
help to calculate specific characteristics of your diamond
(color, clarity and carat weight and cut depending on the
shape of your diamond). Your appraisal is prepared by your
jeweler for the appraised value of the entire item.
TELL ME MORE:
• A diamond grading report will commonly include a plotted
diagram of your diamond and its distinctiveness.
• The report will describe the diamond’s shape,
exact measurements, proportions, depth percentages, as well
as the grade of polish and symmetry.
• Comments on any imperfections will be included in
the report.
• By scheduling an appointment or stopping in, a Don
Basch Jewelers associate can explain to you each portion of
the certificate, while you are visually examining your diamond.
• There are a growing number of labs creating reports.
Let us advise you on the more accurate and reliable certificates,
because many are very “liberal” in their grading.
Remember, your Don Basch Jewelers associate can help aid
you in acquiring a diamond grading report during or following
the time of your purchase!
