HOW TO BUY DIAMONDS WITH
CONFIDENCE AND KNOWLEDGE
By John Tavtin
President
Nebraska Diamond
For the average consumer buying a
diamond can be one of the most confus
aand frustrating experiences imagm
i. The consumer is often confronted
wifi a barrage of conflicting claims from
various jewelers intent on seKng their
product .if flie consumer is notarmed with
adequate product knowledge, he stands
ktfle chance lor success in toe jewelry
marketplace.
A UNIFORM SYSTEM OF
DIAMOND GRADING
Serious shopping for diamonds be
Otoe wito an understanding of tie Gemo
fogteai Institute of America fGiA) and its
diamond grading system. The GIA is a
non-profltcrgartizalondedfcaftBdprimar
flytotoepureufttfgeawtogical education
(towns and operates toe mostprastigious
trade laboratory lor toe identification and
classification of gem stones in tills ooun
tiy . The GIA is considered by toe diamond
industry to be Iho final and most authori
tative word on diamond grading stan
dards in the United States and its grading
system tor diamonds is. by far, the domi
nant grading system used by diamond
cutting firms and jewelry manufacturers
in this country today
Knowledge of the GIA diamond grad
ing system is a pre requisite for informed
buying of diamonds, and knowledge of
that system without an actual “hands on"
demonstration is virtually impossible
The accompanying chart shows a total of
240 separate and distinct combinations
of GIA grades and there is a separate and
distinct price list for each grade within
each size category At Nebraska Dia
mond we give all customers a thorough
explanation and demonstration of the GIA
diamond grading system using actual
examples, so that the oonsumer can see
with his or her own eyes the characters
tics and appearance of the various
graces me two principal reasons why
customers need this special instruction
and knowledge to survive in the jewelry
marketplace are
1 Many jewelers invent their own
personal grading system because by
doing so they make it difficult or impos
sible for the consumer to comparison
shop The GIA system is a uniform sys
tern of diamond grading and gives the
consumer a standard of comparison
2 Jewelers who do represent dia
monds to consumers in GIA terms often
"puff" the grade up to whatever level is
necessary to make the sale A diamond
which is assigned a GIA grade by one of
these jewelers may actually be inferior to
a diamond offered, with a seemingly
lower GIA grade, by a jeweler who ad
heros to the strict grading standards we
use at Nebraska Diamond The untortu
nate result is frequently a customer who
is duped into purchasing a low quality
diamond In our opinion, fraudulent mis
representation of diamond grades repre
sents one of the most serious and wide
spread problems in the jewelry industry
today Your only real protection as a
consumer is to educate yourself about
the product and demand a written guaran
tee At Nebraska Diamond we will show
you how to identify the various GIA
grades by yourself, and we will guarantee
the quality of your diamond in GIA terms

THE RELATIONSHIP OF
COLOR, CLARITY, CUT
AND CARAT WEIGHT
Color, clarity, out and carat weight all
have an important impact on the ultimate
value of your diamond In “The Complete
Guide to Buying Gems” (Copyright 1984,
Crown Publishers, Inc New York), dia
mond authorities Antoinette Leonard
Matlins and Antonio C Ronanno, F G A ,
P G state, “If we were to identity the
factors that determine the value of a dia
mond in order of their importance, we
would list them as follows:
1. Body Color (color grade)
2. Degree of flawlessness (clarity
grade)
3 Cut and proportion (often referred
to as the make)
4 Carat weight”
Color refers to the hue present in the
body of the diamond Color is observed
by placing the diamond upside down in a
white color grading trough and viewing
through the side of me gem Among color,
clarity, cut and carat weight, color is the
characteristic most easily noticed by the
human eye and it has the most impact on
the appearanoe of the gem, hence, oolor
carrios the most value
Clarity refers to a measurement of the
internal flaws and surface blemishes
Resent In or on a diamond Sometimes
lernal flaws and surtaoe blemishes can
be seen only under magnification To
magnify a diamond a leweTor's loupe or a
microscope is used The microscope is
often used more as a sales tool than a
gem Instrument bo cause its "laboratory"
appearance can be Impressive to con
i -—
sumers. The microscope, however, is a
cumbersome pieoe of equipment and is
less flexible than the loupe for examine
tion of diamonds. For these reasons,
among others the loupe is by tar the
dominant diamond grading instrument
used by diamond dealers At Nebraska
Diamond you may view your diamond
under both a jeweler's loupe and under a
microscope designed for professional
diamondexaminatian. Among oolor, clar
ity. cut and cared weight, darity is me
second most observable characteristic
and has me seoood most impact on the
appearance of me gem. hence, darity
carries me second most value
Cut refers to me proportions of me
diamond. A diamond can be cut 10 any
one of an infinite number of proportions
depending on (he angles of me facets
These angles can vary from diamond to
diamond . As explained below, proportion
analysis is extremely subjective and the
effect of differing proportions on me ap
pearance and value of the diamond is
often a matter of opinion. Generally,
however, except for the proportion called
tire heavy make’ discussed below, cutis
a less observable characteristic man
oolor or clarity from a quantitative stand
point and, hence, cut generally carries
less value
Carat weight refers to the weight of
the diamond and not to its size This is an
important distinction because two dia
monds which weigh the same can appear
drastically different in size and this may
result in drastically different values even
if color and darity remain constant
Sometimes consumers forget that size is
a dimensional measurement expressed
in millimeters The term "Carat” is oniy a
weight measurement One Carat is equal
to 1/5 gram If a diamond is cut with its
weight concentrated in its depth, a pro
portion called the "heavy make”, it will not
appear as large as a diamond of the exact
same carat weight cut with its weight con
centrated in its width The difference in
value between these two diamonds can
be substantial, often exceeding *o%
CUT:THE
MISUNDERSTOOD “C”
Among the 4 "C's" (Color, Clarity, Cut
and Carat weight) the subject of diamond
proportioning (Cut) is easily the most
misunderstood The GIA has subdivided
proportion analysis into four Classes
based on table diameter, crown angle,
pavilion depth, girdle thickness, finish
and symmetry Each Class contains wide
parameters for proper proportioning and,
therefore, provides for an infinite variety
of differing cutting proportions, all of
which are considered equally appropri
ate, within each Class The GIA propor
tion evaluation format, thus, illustrates
what every diamond expert in this busi
ness knows that there are literally hun
dreds of different diamond proportions
available which create beautiful and
highly desirable gems
Because there are so many accepted
types of proportioning in diamond cut,
there is no agreement in the diamond
industry on what constitutes the "best"
cut. This is because the main factors af
fected by cut (dispersion, scintillation and
brilliance) cannot ail be maximized in the
same gem
"Dispersion" is sometimes referred to
as "Firer Dispersion means the ability of
the diamond to break down light into the
spectral colors (blues, reds, yellows,
etc ).
"Scintillation" is sometimes referred
to as “Sparkle" Scintillation refers to the
play of light between and as reflected off
me oiamona idcwis
“Brilliance" refers to the ability of the
diamond to return colorless light to the
viewer
There is no such thing as a diamond
cut to maximum dispersion and maxi
mum scintillation and maximum brilliance
all at the same time By cutting to maxi
mize one of these factors, the other two
are compromised, and since all three are
of equal importance, it is impossible to
authoritatively classify one type of cut as
the "best"
In buying a diamond it has been our
experience mat the consumer desires the
most beautiful gem his or her budget can
afford Precisely how dispersion, sdnW
lation and brilliance translate to beauty,
however, is a matter of personal opinion
In their chapter on "The Importance of Cut
and Proportion" mo authors ot “The Com
plete Guide to Buying Gems" siate, with
reference to the percentage measure
ments of various diamond cutting propor
tions , “No one has come to an agreement,
however, on what the percentages
should be, sinoe some people prefer fire
to brilliance and vice versa This is why
there are several accepted types ot pro
portioning found in diamond cut, and
"best" is a matter ot personal preference"
In actuality, the difference in dispersion,
scintillation and brilliance between some
differing diamond proportions Is so slight
that It is measurable only with sensitive
laboratory instruments and is impossible
to see with the naked eye.
As discussed above one area in
which cut makes a big difference in the
value of a diamond ooncerns the “heavy
make" The term “heavy make’ refers to
a diamond that has a disproportionate
share of its total carat weight concen
trated in the depth of the stone Visually,
this means that a “heavy make" diamond
actually weighing 1 carat may only face
up with fie appearance and diameter of a
3/4 carat diamond cut to proper propor
tons Because they face up so much
smaller than they should, "heavy makes"
are worth substantially less than properly
proportioned diamonds Because the
“heavy make" is worth less, it costs the
‘ k less, so he can sell it for less
the jeweler fails to tell his customer
that he is showing a "heavy make" and
fails to explain that the Tieavy make" is
priced lower because it is worth less, the
effect is to trick the consumer into thinking
he has purchased a full size diamond at a
bargain price In fact, the problem of the
“heavy make" is virtually never explained
to the consumer, so the consumer simply
assumes that any diamond shown of a
certain carat weight faces up the size that
it should, and he purchases the “heavy
make" unknowingly We feel that this
failure to inform the consumer constitutes
deception by omission
Seldom is the subject of cut properly
and fairly explained to the consumer At
Nebraska Diamond our customers re
cei ve all of the facts and an explanation of
every option.
HOW TO SPOT
DECEPTIVE TRADE
PRACTICES
Consumers should be aware of vari
ous trade practices which are common in
the jewelry industry but which we feel are
deceptive, unfair and, in many cases,
illegal Deceptive trade practices cost
consumers incalculable sums of money
annually Awareness of these trade prac
tices will assist the consumer in spotting
them and avoiding them when shopping
for fine jewelry
Deceptive trade practices in the jew
elry industry tend to fall generally into two
broad categories:
1. Practices which lead the con
sumer to believe that he is receiving a
bargain purchase when, in fact, he is not
(fake “sales"), and
2. Practices which lead toe con
sumer to bolieve the quality, quantity or
description of the article being purchased
is more or better than that which is actu
ally delivered (active or constructive
misrepresentation of the product either
by actor omission)
The concept of the “fake sale" is an old
one Basically. Itplays on toe desire of the
consumer to obtain a bargain purchase
Here’s.how toe scheme works: The jew
eler places an exorbitant and purely ficti
tious “regular price" or “appraised value”
or ‘reference price” on an article of jew
elry. He then advertises "special sale
prices” or drastic reductions or “store
wide 50% off clearance sale” or certified
savings” or something similar, and offers
tha article to the consumer for less than
this fictitious “marked” prloO The con
sumer buys the article believing he has
reoeived a bargain In fact, though, undor
the scheme, toe jeweler has sold toe
article tor the price he always intended to
sell It for There Is no bargain because the
article really wasn't marked down at aU,
so the consumer actually paid full price
The iake "sale” scheme has reached
epidemic proportions In our opinion, the
fake “sale' is the predominant tool used in
advertised 'price reduction” promotions
in the jewelry industry today Jewelers
who conduct take sales' are simply
betting that their customers are too stupid
to figure out what is going on We think
that is a poor bet Our experience with
consumers convinces us that they are in
kAID ADVERTISEMENT
telligent people who are entitled to be
treated with honesty and respect Any
time you encounter a jewelry “sale”
employing any of the above described
characteristics, we suggest that you
exercise extreme caution Bring a copy
of the “sale" advertisement to Nebraska
Diamond Compare their so called “sale"
prices to our regular everyday prices and
see for yourself why Nebraska Diamond
totally dominates Lincoln's engagement
ring and fine jewelry market
The jewelry industry customarily em
ploys several subtle techniques in an at
tempt to convince the consumer that the
quality, quantity or description of the ar
ticle being purchased is more or better
than that which is actually delivered We
think that these techniques are deceptive
and improper and that consumers should
be warned about them First and fore
most among these techniques is the im
plementation of specialized lighting con
ditions designed to enhanoe the true ap
pea ranee of any gemstone or article of
jewelry. This usually takes the form of
chandeliers, spot lights, flood lamps, and
reflector lamps, both incandescent and
fluorescent, plus tubular incandescent
display case bulbs and other similar type
light sources These light sources are
instantly recognizable by their hot",
"bright" or “intense" appearance Such
lights artificially enhance the appear
ance, brilliance and dispersion in dia
monds and, further, they make it impos
sible to accurately determine the GIA
color and clarity grade In other words,
these lights make the diamond appear
better than it is While others may argue
that the use of this specialized lighting is
merely a merchandising and display
technique, we prefer to think that con
sumers are entitled to see exactly what
they are getting As a practical matter the
only lighting conditions which are non
uc’uofjiivo, si int 19, *»i hwi i piuaui is u iw u *«w
appearance of gemstones and articles of
jewelry, are natural daylight and color
corrected tubular fluorescent lighting
which simulates natural daylight Even
this light, in order to be non deceptive,
must be presented in a dosed and care
fully controlled environment, undiluted
and uncontaminated by other light
sources These are the lighting condi
tions which are used for laboratory grad
ing of diamonds, and these are the light
ing conditions you will find at Nebraska
Diamond At Nebraska Diamond we sell
quality jewelry, and we adhere to the phi
losophy that when you sell qual'tyjeweli y
you don't need deceptive lighting condi
tions
THE CONSUMER’S
RIGHT TO KNOW
The ultimate purpose for the con
sumer to acquire product knowledge is to
enable him or her to separate "fact' from
"sales pitch.* Your right as a consumer to
know the facts is unequivocal, and
should include nothing less than the fol
lowing :
1 You have the right to demand that
the jeweler accurately grade your dia
mond in oonformity with the Gl A diamond
grading system, that he fully disclose that
grade to you and show you now the grade
was determined, and that he provide you
with a written warranty guaranteeing the
authenticity of that grade Never pur
chase a diamond without such a disclo
sure and warranty
2 You have the right to examine
your diamond loose before making your
purchase. You cannot accurately ob
serve the color or clarity of a diamond
which is set into a ring Never purchase
a diamond that you have not examined
loose.
3 You have the right to examine your
diamond under the lighting conditions
used for laboratory grading of diamonds,
that is, under natural daylight and under
color corrected tubular flu orescent light
ing which simulates natural daylight, in a
closed and carefully controlled environ
ment undiluted and uncontaminated by
other light sources Never purchase a
diamond that you have not examined
under such lights
4 You have the t ight to examine the
color of your diamond in a white color
grading trough and to examine the clarity
of your diamond under a loupe or micro
scope, and you have the right to expect
the jeweler to point out exactly what you
should see Never purchase a diamond
that you have not examined in this man
ner
5 You have the right to ask any
questions pertinent to your purchase and
you have the right to expect a courteous,
informed, accurate and complete an
swer Never purchase anything from a
jeweler who shows disrespect for your
right as a consumer to know.
