are a great many things to know about Diamonds and the Diamond Industry.
By reading books and the information available on the Internet,
you can learn a lot, but that still doesn't help you much in physically
grading a Diamond or going through the Diamond buying process. Nonetheless,
if you know the right things you can have better
success rate in buying a Diamond for a fair price. Here is a shortlist
of the things you need to know.
But beware, just
as it can be very tough to buy a new or used car, Diamonds are a
complicated business and it's not always an easy process.
as much as you can about Diamonds. Unless you feel that Dollar
Bills are like so much paper, I can think of several thousand
motivations to "know your stuff" about Diamonds. We
have prepared a Diamonds Tutorial
for you. Once you have completed that you may wish to browse

which properties of Diamond are most important to you. Write
down, in order of importance, which of the 5C's you care most
about: Cost, Carat, Color, Clarity or Cut. Most people want
BIG. There's absolutely nothing wrong with that. But we'd like
you to be aware of what you may be giving up in exchange for
a big stone. When we show people two stones with similar properties,
one a bit smaller with a better cut and the other a bit bigger,
but not as good a cut, they will usually prefer the better cut.
If you find a Jeweler who will be willing to show you the difference,
it may be worth your time.
Jewelry Stores and get the market price for
the type of Diamond you are looking for. Look at the quality
of the stones they are quoting you. Note, please make sure when
comparing prices that you compare apples to apples. This is
actually very hard to do. For example, minor differences in
cut, in proportions can have a severe impact on a stone's price
and beauty. A most important point to remember is not to compare
the price of a certified Diamond with a price of a Diamond which
is not certified, or is only certified by a no-name brand Laboratory.
You may be in for a surprise.
for a certificate. There are several Independent Laboratories
out there. The most well-known is GIA, the Gemological Institute
of America. GIA has done a great service by providing the public
a metric to compare Diamonds and Diamond prices from different
suppliers / jewelers / dealers. Nonetheless, if you don't know
the rules of the game, even this won't help you. For example,
you should be aware of the differences between an appraisal
by a G.G. (GIA Gemologist) as opposed to a GIA GTL Certificate.
Read more about it in "Certificates
vs. Appraisals". Beware of no-name brand Laboratories,
no-name brand Certificates and no-name brand Appraisals. You
may wind up with something "less" than agreed upon.
There are respectable non-GIA Laboratories out there. For example,
EGL, the European Gemological Laboratory. Please note that EGL
has several Labs all around the world, each is independently
owned, and may have different procedures and even grading. If
you have any doubts, feel free to post a message in DiamondTalk.com

Rapaport Diamond Report (Rap
Sheet). There is a standard report of Diamond Prices known
as the Rap Sheet. This officially lists high wholesale diamond
prices in the NY market. The reality is that usually wholesalers
speak to each other about prices in terms of the percentage
discount to the Rap Sheet. How much of a discount to Rap? It
really depends on the quality of Diamond you are looking for.
On the wholesale market, Diamonds of some qualities are sold
at a deeper discount to Rap than other qualities. There are
market fluctuations which change according to supply and demand.
The best way to know prices for the specific Diamond you are
looking for is to shop around for a Certified Diamond of a quality
range you desire, within your budget.
for corresponding Color and Clarities. In other words, don't
buy a High Color/Low Clarity or High Clarity/Low Color Diamond.
In a similar vein, why pay a premium for an Ideal Cut Diamond,
and then accept a lower color and clarity? You pay a serious
premium for getting say an E Color Diamond. What's the purpose
of paying that premium and then buying an SI2 Diamond? Why not
go down a color or two and increase one or two clarities? This
is a very common practice.
safe to buy a Diamond on the Internet? Good
question. Sometimes yes, sometimes no. If you make sure you
know who you're dealing with, it can be. Just because you found
a good supplier on the Internet, it doesn't mean you can't make
an effort to visit them in person. Of course sometimes distances
make it impractical. In those cases you have to judge for yourself
if it's safe to do business with them. If you do decide to take
the risk, make sure that you only buy a certified stone, and
make sure they offer a guarantee that if you don't like the
stone after viewing it, that you can return it. By the way,
buying a Diamond "off" the Internet is not necessarily
you started, try out our Multi-Jeweler
