The beauty and rarity of colored diamonds in nature
pushed us to learn more about the properties of their color
in order to be able to reproduce those colors in the labs.
Over the past decades, scientists explored and introduced
methods to bring color onto cultivated diamonds. While some
methods change the color only temporary others bring about
permanent change with no damage to the structure of the crystal.
Irradiation and HPHT are the methods that provided the best
In order to explain how we create our color diamonds we must
take a step back and look at how colors occur in natural diamonds.
The presence of color in a diamond is often defined by structural
anomalies and the presence of other mineral atoms in the crystal.
Those atoms become part of the crystal mattrix lattice during
its growth and in the end will affect the light absorption
within the crystal. Tints of naturally colored diamonds will
depend on those extras in the lattice and will be seen as
one of the following colors: steel grey, blue, green, yellow,
orange, pink, red, purple, brown or even black.
Tints of yellow, orange and brown often appear due to the
presence of a higher Nitrogen content in the atomic structure.
So whether or not Nitrogen was added "accidentally" by nature
or on purpose by a scientist, the result is the same —
the diamond has a yellow color that may vary from slightly
yellow to intense orange or brownish colors. All our yellow
to brown colored diamonds acquire their color in the same
way as natural crystals do, simply by having Nitrogen added
at a very early stage of formation.
Similarly the blue colored diamonds get their stunning gentle
blue color due to the presence of Baron atoms in their structure.
To bring green to a diamond, some extra thermo baric treatment
is applied that will result in a lively, sparkling light green
color. For our deep red colored diamonds we use the method
of irradiation, which has been developed and successfully
applied throughout recent decades.
All colored diamonds grown in our lab have a lively
intense color that will last and will not fade with time.
Clarity is one of the 4 'Cs' of characteristics developed
within the diamond industry in order to describe diamond quality
on the market. The grading scale that was built for natural
diamonds also applies to our lab-grown stones.
Similar to a naturally grown diamond, a lab grown crystal
may have inclusions, because an absolutely pure diamond without
any defects is quite rare natural phenomena.
Cultivated diamonds grown in the Labs of New Age Diamonds
are on average graded between I, SI, VS scale.
