Understanding
The Real Beauty Of A Black Diamond
The black diamond was once considered worthless
and flawed but today, it is quickly becoming one of the most
sought-after gems because of its unique and exquisite quality.
However, not all gems are equal. That is why; interested buyers
have to study more on its characteristics before finally making a
purchase.
What is a Black
Diamond?
Compared with some most coloured diamonds that
characterize their dazzling hues because of chemical impurities
that grow right within its crystal lattice, a black diamond
provides smoky colourations from its mineral inclusions.
These minerals are usually sulphide compounds,
hematite, and magnetite. Higher concentrations of these inclusions
generally cloud the stone, thus turning it into a rich or black
colour.
Since this tinting is typically caused by the
inclusions instead of some impurities, a black diamond is usually
opaque, although semi-transparent and translucent specimens are
considered as extremely valuable.
A natural black diamond has been located in
Australia, Venezuela, Africa and Brazil, and more of these are
believed to have been shaped by meteor impacts.
Carbonados are a specific type of a black
diamond that holds very little value in the whole of the jewelry
industry. They are commonly large but are very much porous, unlike
the crystalline structure of diamonds used in jewelry.
Although less valuable, carbonados are used as
abrasives to cut and shape other diamonds. Additionally, they are
more common than those gem-quality stones.
Synthetic Black
Diamond
Since a black diamond is starting to gain its
popularity, different treatments have been developed just to meet
the growing demand. It may be synthetically grown in a laboratory,
while inferior diamonds may be irradiated to attain a smoky black
coloration.
Also, annealing, or commonly called heat
treatment, can also be used on low-quality gems. Stones are
generally exposed at higher temperature until a graphite residue
appears in the crystal, providing it with a gray or a black
tint.
Another method to create a gray or black diamond
is injecting carbon dioxide into plasma. This will result into
crystals that normally have a black hue.
When you buy a black diamond, always make it a
point to carefully investigate whether that stone is synthetically
enhanced or not. If it is treated, the stone normally requires a
special care to refrain from damaging the treatment.
A black diamond is very luxurious and rare. If
you wish to be unique with your pieces of jewelry, try considering
it to exude a powerful and a dramatic statement.
