At Stunning Diamonds we use 100% Real Natural Diamonds in
all our diamond jewellery.
Every diamond used in our jewellery was mined from the
earth, is conflict free and not treated or altered in any way apart from basic
cutting, polishing and cleaning. We do not sell artificially enhanced,
synthetic or lab created diamonds.
This is worth explaining when you understand
that many jewellers, diamond traders and websites deal in artificially enhanced
diamonds and unless you are aware of this and know to check - you could
end up with diamonds that are not 100% Natural when you presumed they
If you are planning on buying diamond jewellery it is
extremely important to be aware of artificially enhanced diamonds and
to know if the diamond(s) in the item you intend to purchase have been augmented in any
way so you don't over pay or end up with artificially enhanced diamonds
when you thought they would be all natural.
Many times it will be extremely difficult to detect if a diamond
has been artificially enhanced. If you look closely you may be able to see a small
drill hole from laser drilling or you may notice cloudy spots that may
indicate enhancements. However, your best bet is to ensure the
diamond seller provides a gemmology appraisal. Having a gemmologist
assess your diamond jewellery and do certain tests to
determine if the diamond(s) are enhanced is the best course of action for any
consumer buying diamond jewellery.
Every item of diamond jewellery supplied by
Stunning Diamonds comes with an appraisal outlining the exact make up of
the diamonds and goldsetting.
Natural Diamonds V's
You may be wondering what all the fuss is about
artificially improving a diamond's gemelogical characteristics. The truth of the matter is that a diamond
is more valuable when it has not been artificially augmented. Besides
general polishing and diamond cleaning, any other artificial
enhancements to improve the colour or clarity of the diamond(s) in your
diamond jewellery will result
in a lower valued item.
For some people buying enhanced stones is
attractive, they purchase a beautiful looking stone for much less than
an untouched diamond, however the problem lies with shady diamond
salesmen that will fraudulently sell you a diamond that has been
artificially manipulated for the same price as an untouched stone. This
is why it is extremely important to understand diamonds and the
processes in which a diamond can be artificially enhanced so that you can
make an educated and informed decision when buying diamond jewellery.
If a diamond has had other augmentation done to it
besides basic cutting, polishing and cleaning it must be openly stated
with full disclosures according to FTC rules. Although diamond
augmentation must be disclosed to the buyer, unfortunately many diamonds
that have had fracture filling, laser drilling or other types of
treatments are never disclosed to the buyer by shoddy diamond traders
and the consumer pays full price for a diamond that in reality is worth
In addition without having an understanding of what
the word "enhanced" means in relation to diamonds the consumer may be
under the misunderstanding that this is in fact a good thing.
Bottom line - if you expect to have 100%
Real Natural Diamonds in your diamond jewellery then you need to check
with the seller that is in fact what you will get. Otherwise you may end
up paying more for your diamond jewellery than it is actually worth and
after all you won't have 100% Real Natural Diamonds!
Below is an outline of how diamonds can be
Diamond enhancements are specific treatments,
performed on natural diamonds (usually those already cut and polished
into gems), which are designed to improve
the gemmological characteristics - and
therefore the value â€” of the stone in one or more ways. These include
clarity treatments such as
laser drilling to remove inclusions,
application of sealants to fill cracks, colour
treatments to improve a white diamond's colour grade, and treatments to
give fancy colour to a white or off-colour diamond.
The combustibility of diamond has allowed the
development of laser drilling techniques which, on a microscopic scale,
are able to selectively target and either remove or significantly reduce
the visibility of crystal or iron oxide-stained fracture inclusions.
Diamonds have been laser-drilled since at least the mid-1980s. Laser
drilling is often followed by glass infilling.
Several inclusions can be thus removed from the same
diamond, and under microscopic inspection the fine bore holes are
readily detectable. They are whitish and more or less straight, but may
change direction slightly, and are often described as having a
"wrinkled" appearance. In reflected light, the surface-reaching holes
can be seen as dark circles breaching the diamond's facets. The diamond
material removed during the drilling process is destroyed, and is often
replaced with glass infilling, using the fracture filling techniques
Around the same time as the laser drilling
technique was developed, research began on the fracture filling
of diamonds to better conceal their flaws. The glass filling of diamond
often follows the laser drilling and acid-etching of inclusions, though
if the fractures are surface-reaching, no drilling may be required.
The glass present in fracture-filled diamonds can
usually be detected by a trained gemmologist under the microscope: the
most obvious signs - apart from the surface-reaching bore holes and
fractures associated with drilled diamonds - are air bubbles and flow
lines within the glass, which are features never seen in untreated
The fracture-filling of diamond is a controversial
treatment within the industry - and increasingly among the public as
well - due to its radical and impermanent nature. The filling glass
melts at such a low temperature (1,400 °C or 1,670 K) that it easily
"sweats" out of a diamond under the heat of a jeweller's torch; thus
routine jewellery repair can lead to a complete degradation of clarity or
in some cases shattering, especially if the jeweller is not aware of the
treatment. Similarly, a fracture-filled diamond placed in an ultrasonic
cleaner may not survive intact.
It is notable that most major gemmological laboratories
refuse to issue certificates for fracture-filled diamonds. Labs that do
certify these diamonds may render any treatment benefit moot by
disregarding apparent clarity and instead assigning the diamond a grade
reflecting its original, pre-treatment clarity.
Generally there are three major methods to
artificially alter the colour of a diamond: irradiation with high-energy
subatomic particles; the application of thin films or coatings; and the
combined application of high pressure and high temperature (HPHT).
However, there is recent evidence that fracture filling is not only used
to improve clarity, but that it can be used for the sole purpose to
change the colour into a more desirable colour as well.
The first two methods can only modify colour, usually
to turn an off-colour Cape series stone into a more desirable fancy-coloured
stone. Because some irradiation methods produce only a thin "skin" of
colour, they are applied to diamonds that are already cut and polished.
Conversely, HPHT treatment is used to modify and remove colour from
either rough or cut diamonds-but only certain diamonds are treatable in
this manner. Irradiation and HPHT treatments are usually permanent
insofar as they will not be reversed under normal conditions of
use, whereas thin films are impermanent.
Clarity Enhanced Diamonds
One of the most valuable traits of a diamond is its
clarity. However, many diamonds that have imperfections are artificially
manipulated to increase this trait, this process is called clarity
enhancement and while it may make a diamond look aesthetically pleasing,
it is not always beneficial for the buyer.
There are a few ways in which the clarity of a diamond
can be manipulated. One of the more common methods is to drill a tiny
whole in the diamond in order to remove an inclusion which is minerals
or elements that can cause discolouring. Other methods include filling
cracks or fissures in a diamond with sealant and colour treatments that
try to improve a diamonds colour or to give the diamond an exotic hue.
Possibly the most common way a diamond is clarity
enhanced is by drilling. Many diamonds that are the right size and
but have inclusions which are generally iron oxide or more commonly
called rust usually are candidates for drilling. Drilling is usually
done with a laser which neatly makes a small hole down through the
diamond to the inclusion. Acid is usually used to remove the rust from
the diamond making it clear of any inclusions. At this point the diamond
may be left with a small fracture or it may be filled, usually with
heavy glass that is unnoticeable to the naked eye. This technique of
filling fissures, drilled holes and fractures is known as fracture
filling and can take place in diamonds that were drilled to remove
inclusions or diamonds with small fissures. Instead of heavy glass,
small cracks and fissures can also be filled with tiny diamond vapor
depositions which are almost undetectable as well.
