4C’s- When searching for diamond most principal features to develop is 4C’s (CUT,
CARAT,COLOR,CLARITY).
It is been recomended to give DIAMOND CUT the centre of attention of all.
The hardness of diamond also stand as a important feature while selecting diamond. Real diamonds
doesn’t get break away that easily because of its strength and formation process.
Diamond gets their intensity from three artefact. (REFLECTION, REFRACTION AND DISPERSION).
When the Reflection of light smacks the diamond and instantly rebound back with a shine is a sign of
Real Diamond.
Refraction term in a diamond is the place when light is moving from one medium to another
medium, and speed of light in the vaccum is 2.42 times the speed of light in diamond.
DISPERSION in diamond is a attractive effect when light travel o a diamond and gets divided to all the
rainbow color and gives back a magnificient view to a user’s eye.
Certificate
You should check the certificate of your purchased diamond. Diamonds there are certain certificates
for authenticity and trust. These certificates can include Diamond quality, serial number on the
girdle, validity that it is organic, color, clarity, weight etc.
There are labs which issue the certificate, details irrespective of the Diamond’s market value. For
quality Diamond and authenticity, ensure that the grading certificate issued is of a reputed lab.
Some labs offer online services, you can verify the specifications. You can also ask the seller the
process and the origin of the diamond.
Conflict Free
There are so many lives associated with diamond processing; you should need to know that whether
the diamond is coming from legitimate and ethical way or not. When buying a diamond product,
consumers should ask for a guarantee that the diamond is conflict-free. It is your duty to make sure
that the diamond product you buy is clean with no tear or blood on it. Your money should go into
right hand. It shouldn’t be at the cost of lives of innocent people. Your urge for a conflict free
diamond will play an important part maintaining peace in our beautiful world.
Check For ‘Scratches’ Caused by Improper Polishing
Once the diamond is cut, each of its facets is polished; in case this is not done perfectly, it may lead
to easily visible scratches on the exterior surface of the diamond. These blemishes are similar to
those left behind on a car after waxing. Therfore, it’s best to go for diamonds that have no or few
scratches.
HERE IS HOW TO CHECK IF A DIAMOND IS AUTHENTIC OR NOT.
FOG :
For the fog test, hold the diamond or ring between two fingers and breath on it with a puff of air. A
light fog will form on the diamond because of the moisture and heat in your breath.
If the fog dissipates right away, the diamond is real. If it takes several seconds for the fog to disperse,
it is likely a fake diamond.
Diamonds effectively conduct heat and therefore disperse heat quickly.
WATER:
This one's easy: Get a glass and fill it with water (it doesn't matter what type of water you use). Drop
the diamond into the glass of water. Due to the high density of diamond, when dropped into water a
real diamond will sink. If the diamond floats to the top or middle of the glass, it's fake. It's simple
physics.
Check the setting and mount:
A real diamond is not likely to be set in a cheap metal. Stamps inside the setting indicating real gold
or platinum (10K, 14K, 18K, 585, 750, 900, 950, PT, Plat) are a good sign, while a "C.Z." stamp will give
away that the center stone is not a real diamond. C.Z. stands for Cubic Zirconia, which is a kind of
synthetic diamond.
Use a jeweler's loupe to inspect the diamond
You can usually borrow one from the jewelry store. Mined diamonds usually have small naturally
occurring imperfections, which are called "inclusions," that can be seen with a loupe. Look for small
flecks of minerals, or very slight color changes. These are both signs that you're dealing with a real,
albeit imperfect, diamond.
Heat the Stone and See if it Shatters:
Diamonds are made of incredibly strong material and will be unresponsive to high heat.
To test this, grab a drinking glass and fill it with cold water. Use a set of plyers or fireproof gloves to
hold the stone. Heat the stone with a lighter for approximately 40 seconds, then drop the stone
directly into the cold water.
If the stone shatters, it is made of weaker components and is not a real diamond. A true diamond will
show no reaction.
This method tests the quality and strength of the stone. Because of the quick expansion and
contraction of heat, weak materials like glass or cubic zirconium will crack and break. Think of a glass
or Pyrex dish you use for cooking. If you pull the dish out of a hot oven and try to wash it
immediately, the shock in temperature change may shatter the dish.
Because diamonds are one of the strongest materials on the planet, it will be resistant to such heat
tests. Heat will disperse quickly and the diamond won’t be affected by the change in temperature.

Brief History of GIA
Founded in 1931, the Gemological Institute of America (GIA) is an independent, non-profit
organization widely considered as the world's foremost authority in gemology. Introduced in 1953,
their diamond and gemstone grading system is recognized as an accepted standard worldwide.
Gemstone manufacturers from around the globe send diamonds and gems to the GIA for expert
examination and analysis.
GIA Diamond Grading
The GIA Diamond Grading Report is issued for diamonds that fall in the D-Z color range. This detailed
report includes a full quality analysis of shape and cutting style, measurements, carat weight, color
grade, clarity grade, cut grade (for brilliant round-cut diamonds), polish and symmetry assessments,
and fluorescence. The report also includes a plotted diagram indicating the relative size and location
of clarity characteristics, a proportion diagram, and GIA grading scales.
HISTORY OF AGS
In 1934, a small group of jewelers who wanted to protect buyers from false advertising and fraud in
the diamond industry established the American Gem Society (AGS). They were the first organization
to release a diamond cut grading system when they did so in 1966.
Today, the AGS provides retailers, jewelers and individuals with gemological knowledge, research,
consumer protection and standard grading of diamonds. With clear and consistent grading, the AGS
is one of the most trusted lab grading entities in the world.
AGS DIAMOND GRADING REPORT
The AGS evaluates each diamond based on its qualities and components. It issues a grading report
that includes details on everything from the cut quality to the carat weight. When reviewing an AGS
diamond grading report, look at each aspect to verify what you’re buying.
Diamond Quality Report
The AGS diamond quality report gives you grading and description of the diamond you’re buying. It’s
a complete analysis offered for round brilliant, oval, emerald, princess, and cushion cut diamonds.
As you can see in the report below, the AGS diamond grading for the cut, color, clarity, and carat are
all listed. There are further details under Cut such as light performance, symmetry and polish. You
can also see important measurements of the diamond’s table, pavilion, and other components.
There’s also a plot showing any inclusions on the diamond.
IGI DIAMOND CERTIFICATION
The IGI started out as the blue color workhorse of the diamond business.
They were the most popular gem lab for the major jewelry chains in the US and Canada (Kay, Zales,
etc.)
They are like a factory. They work fast, and their prices are much better than GIA’s and AGS’s.
Before we define exactly what a ‘conflict-free’ diamond is, it’s important to understand the term
‘conflict diamond’ (also referred to as ‘blood diamond’). These diamonds are defined as, “illegally
traded to fund conflict in war-torn areas, particularly in central and western Africa, according to the
World Diamond Council, which represents the commercial diamond trade.”
So what are conflict-free diamonds? Back in 2000, many states in South Africa had had enough. They
met to agree upon a process that would stop the trade of conflict diamonds. In the end, over 70
countries, the United Nations, the World Diamond Council, and the European Union agreed upon an
organization aimed at encouraging ethically sourced diamonds, commonly known as the Kimberley
Process — formally known as Kimberley Process Certification Scheme (KPCS).
As a member of the Kimberley Process, you’re ensuring that your diamonds are ‘conflict-free’ and
you cannot trade with non-members. The goal was to push out individuals who were still
participating in illegitimate practices and try to bring peace to many of the war-torn areas.
However, the only proof of a batch of diamonds that have gone through the Kimberley Process is a
certificate that details where the diamonds were mined, how they were extracted from the earth,
where they were cut and polished, and their intended destination. And while it may be easy to
assume that the process guarantees ethical diamonds, difficulties came when it was discovered that
members of the KPCS were continuing unethical practices and getting away with it due to lax political
will.
Less expensive The price of a lab-created diamonds tends to be less than mined diamonds.
However, this does not mean that a lab-created diamond is “cheap.” In fact, the capital costs for lab-
grown and mined diamonds are pretty similar.
So, why are lab-created diamonds less expensive? Mined diamonds and lab-created diamonds have
the exact same costs when it comes to cutting, polishing, and inspection. However, up to that point,
the costs and processes are very different.
Mined diamonds have a long supply chain. To get a diamond from its raw form to a retail-ready
gemstone requires miners, distributors, cutters, polishers, jewelry manufacturers, and retailers.
On the flip side, the lab-created diamond supply chain is much shorter by skipping the mining
process. To put it simply, a lab-created diamond touches fewer hands, making it ultimately less
expensive.
Ethical Several years ago, the mined diamond industry came under scrutiny with unethical
production practices were exposed. These diamonds, sometimes referred to as blood or conflict
diamonds, were funding violence and exploiting miners and their families.
Thanks to the Kimberley Process, established in 2003, these unethical practices have been
significantly reduced. In fact, it’s estimated that 99.9% of natural diamonds are now conflict-free.
However, if avoiding conflict or blood diamonds is important to you, lab-created diamonds provide
peace a mind that a natural diamond often cannot, and you may find reassurance in knowing the
exact origin of your diamond.
Environmentally Kind As with the mining of any natural resource, the diamond mining has a
significant impact on the environment. To be fair, diamond mining companies are fully aware of that
impact and have taken steps to try to minimize the effect they have on the ecosystems around them.
However, lab-created diamonds are inherently and significantly less detrimental to the environment
as it takes considerably less energy to grow a diamond in a lab than it does to dig it out of the
ground. In fact, it is actually in the interest of the growers to minimize the amount of energy they use
in the process to save money and decrease their costs.
The remarkable technology behind hpht and cvd diamonds.
The dream of making a beautiful and valuable diamond from simple carbon has long captivated the
imagination of scientists and visionaries alike. Just like the alchemists of old who sought to turn lead
into gold, many have tried to achieve this impressive feat. We have only recently been able to
produce gem quality, lab grown diamonds that are large enough to be used in jewelry. But, how is it
done?
Early Efforts
Throughout history, many people have claimed to have successfully synthesized diamonds. However,
it was not until relatively recently that a documented and reproducible process was demonstrated.
Henri Moissan was one of the early pioneers in the field. In 1893, he claimed to have successfully
made a diamond by heating charcoal to 3,500 degrees Celsius inside a carbon crucible. Many
attempts were made to reproduce his techniques with some reported successes, but none could
ever be scientifically verified. The quest continued.
Diamonds are a crystalline form of carbon, and so making artificial carbon crystal was the problem of
lab grown diamonds. For decades, manufacturers of synthetic gemstones tried growing diamonds
like they grew rubies, sapphires, and emeralds. It failed. Then they had the idea to grow diamonds in
the lab like they grew in nature.
HPHT DIAMONDS
When using the HPHT process, pure carbon and a tiny piece of diamond referred to as a starter seed,
are placed in a high pressure, high temperature chamber. As the carbon is heated, it melts around
the starter seed and a diamond is created. At this time, the HPHT process makes it possible to create
much larger diamonds than the CVD process.
CVD DIAMONDS
A diamond made using CVD begins with a narrow slice of diamond seed and places it in a sealed
chamber. By filling the chamber with hydrocarbon gas mixtures and ionizing them into plasma using
lasers, microwaves and other techniques, the molecular bonds in the gases are broken and the pure
carbon sticks to the diamond seed. This process does not require high pressure and the
temperatures, while still high are nowhere near what is required for HPHT.
Lab-created diamonds (which have also been referred to as lab-grown diamonds, synthetic
diamonds, artificial diamonds, cultivated diamonds or cultured diamonds) are man made diamonds
that mirror real, natural diamonds. Because they actually consist of carbon atoms structures, lab-
grown diamonds display the same chemical and optical characteristics of a natural diamond crystal
produced by the geological processes of Mother Nature. Synthetic diamond prices are generally
lower than real diamonds, and the price of lab-created diamonds continues to drop (as much as 30%
in a year). This is due to lab-grown diamonds not having any resale value and that the demand for
lab-grown diamonds continues to decrease.
You can’t tell the difference between lab-created diamonds and real diamonds without specialized
equipment, even if you’re a professional gemologist. The best way to tell the difference between lab-
grown diamonds and real diamonds is to look at the grading report.
If a professional gemologist is determining if a diamond is real or lab-grown, they use magnification
to look at the nature of the inclusions. The inclusions in a natural diamond appear slightly different
than in a lab-created diamond. There are sometimes also differences in how the diamond reflects
light compared with a synthetic diamond.
In general, though, when looking at a lab-created diamond next to a real diamond, you can’t
distinguish the two.
Half carat diamond is considered to be most ideal for rings and pendants. However, for earrings 1 carat total diamond weight is the most ideal.
