Cultured diamonds are lab-grown diamonds
that possess the same sparkle, brilliance, fire and
hardness as earth-mined diamonds. Each diamond is carefully
and individually cultivated into some of the most rare
and desirable colors.
These diamonds are the perfect way to experience first-hand
the passion and excitement of owning an amazing, fancy-colored
diamond.
Similar to a cultured pearl, a cultured diamond is a
diamond that has had assistance in the growth process.
Instead of being mined, our cultured diamonds are grown
and monitored in a laboratory where it takes more than
100 hours to grow each one.
Each cultured diamond is grown individually, one by
one, and the result is a spectacular fancy colored diamond
with the exact same chemical, optical and physical properties
as their mined counterpart. Every single diamond also
has the same toughness as a natural fancy colored diamond;
therefore they are cut and polished in the same manner.
What makes our fancy colored cultured diamonds so unique
is that each diamond is grown individually depending
on the desired size and color. These diamonds are not
mass produced and are grown one at a time. By applying
the appropriate pressure and temperature for common
carbon to rearrange its atoms, carbon will change its
phase and re-form into a diamond crystal. The result
is a superb rough diamond crystal that can be cut and
faceted like a mined diamond.
If you are looking for a fancy colored diamond in a
particular shape or size that is not listed here, please
contact us and we will let you know when one is available.
Our yellow cultured diamonds are available in fancy
shapes from time to time. Our pink and blue diamonds
are only available in the round brilliant cut at this
time. Just fill out our custom request form and we will
respond within 24 hours.
Cut
All of our fancy colored cultured diamonds are cut to
exact specifications to yield the best proportions,
as we want all of our diamonds to be as symmetrical
and precisely cut as possible. Each diamond is faceted
and polished by the most skilled diamond cutters in
the world to provide a diamond with very good polish
and symmetry.
Our round brilliant diamonds have very good brilliance
and even distribution of color with no color zoning.
Color
Fancy colored diamonds are diamonds with any noticeable
depth of bodycolor. Red and green are the rarest fancy
colors, followed by purple, violet, orange, blue, pink
and yellow.
The bodycolor of a fancy colored diamond can be evaluated
by looking at the following three criteria:
• Hue: The basic color of a diamond.
• Tone:
A scale ranging from light to dark, indicating color
intensity.
• Saturation: The color strength, purity or intensity
of a diamond.
Our fancy colored diamonds are classified using non-gemological
terms so that our customers can identify with the colors
better. On EGL (European Gemological Laboratory) grading
certificates however, fancy color grades are described
using the following terms:
• Faint
• Very Light
• Light
• Fancy
• Light Fancy
• Fancy Intense
• Fancy Vivid
Fancy Yellow Diamonds
The most valuable natural fancy yellow diamonds have
a distinct hue, darker tone, and vivid or strong color
saturation. The more even and saturated the diamond,
the more rare and valuable it is.
We offer our fancy yellow diamonds in five color ranges:
light canary yellow, canary yellow, light marigold yellow,
marigold yellow and amber yellow.
Below is a chart which lists our color grading terms
with a more detailed description of the hues.

Fancy Pink Diamonds
Our fancy pink diamonds have a distinctly pink bodycolor
and are extremely rare in nature. The most valuable
natural fancy pink diamonds have a distinct hue, medium
tone and vivid color saturation.
We offer our fancy pink diamonds in five color ranges:

and intense pink.

Clarity
We use the most skilled cutters for our fancy cultured
diamonds; therefore we only have diamonds with the
highest clarity ratings. Our diamonds range from SI
(Slightly Included) to VS (Very Slightly Included).
Our VS diamonds are eye-clean and have minute inclusions
that are difficult to see with a 10x loupe. Our SI
diamonds are also eye-clean with small inclusions
that are somewhat easier to see with a 10x loupe.
Carat
Our fancy yellow cultured diamonds can be grown between
0.02 ct. to 1.5 ct. If there is a specific size you
are looking for, please fill out our custom request
form and we will let you know if we have that available.
Our fancy pink and blue diamonds can be grown between
0.02 to 0.70 ct. If there is a specific size you are
looking for, please fill out our custom request form
and we will let you know if we have that available.
Shape
We offer our fancy yellow diamonds in the round brilliant
cut. Occasionally we have fancy shaped yellow diamonds
available in the princess, asscher, emerald, cushion
and radiant cut. We will list these diamonds under
“Featured Diamonds”.
We offer our fancy pink and blue diamonds in the round
brilliant cut only. We do not have fancy shapes available
at this time.
Certification
Upon special request, we can arrange to have your
Gemesis or Chatham cultured diamond graded by an independent
diamond grading lab such as the EGL (European Gemological
Laboratory).
This service is complimentary for diamonds 1.0 ct.
and over and must be requested while purchasing. For
diamonds 0.99 ct. and under, each certificate is $125.00.
After your diamond is sent to EGL, please allow 5
to 15 business days for the certification and grading
process. For more information, please call us at:
800-594-8873.
Synthetic (Cultured) Diamond vs. Diamond Simulant
Synthetic (Cultured) Diamond
A synthetic diamond is a man-made, lab-created cultured
diamond, produced either by subjecting carbon-bearing
material to high temperature and pressure or by the
chemical vapor deposition method.
Synthetic diamonds have the same chemical, physical
and optical properties as their natural counterparts.
Gemesis and Chatham cultured diamonds are synthetic
diamonds.
Diamond Simulant
A diamond simulant is any material which is not diamond
or synthetic diamond, but which simulates or imitates
a diamond’s appearance and is used in its place
as a substitute.
Common diamond simulants include cz (cubic zirconia),
glass, plastic, russian brilliants, asha and moissanite.
Cultured Diamond vs. Mined Diamond Comparison
Our cultured diamonds possess all of the qualities
of a mined diamond: unequaled hardness, fire, brilliance
and scintillation. Just look at the comparison chart
below to see how a cultured diamond compares to a
mined diamond on these ten characteristics.
