What is the quality of a MiaDonna Diamond Hybrid and Mountings?
Color:
Color describes the amount of color the diamond contains. This can range
from colorless to yellow with slight tints of yellow, gray or brown. Colors
can also range from intense yellow to brown, blue, green, pink and red.
It is very rear and extremely expensive to find colorless earth mined
diamonds.
The MiaDonna Diamond perfectly mimics the diamond's crystal structure
(face-centered-cubic) resulting in a virtually identical look as fine
diamond. It grades F-G on average (the consensus of five gemologists)
but new studies show our diamond hybrids are now becoming D to F on average.

Clarity:
Clarity describes the clearness or purity of a diamond. This is determined
by the number, size, nature, and location of the internal (inclusions)
and external (blemishes) imperfections. Earth mined diamonds nearly always
have a birthmark.
The clarity scale is broken down into the following grades:

Durability:
Testing via the hammer smash test indicates that our MiaDonna Diamond
is the toughest, most durable diamond product we have ever tested. On
the Mohs
hardness scale it scores approximately 9.6 to 9.8 on it outer diamond
layer and approximately 9.1 on the whole stone including the center seed.
(Natural diamond scores 10 as the hardest mineral.)
Cut:
The MiaDonna Diamond Hybrid is hand-cut to precision and grades better
in every aspect of the GIA diamond grading scale than most diamonds. Only
1 in 1000 diamonds will get this level of cutting perfection. For example,
it takes our cutters 8 times as long to cut a MiaDonna Diamond Hearts
and Arrow (H&A) as to cut a typical round diamond.
While color and clarity are big factors in the cost of a diamond, it is
the 'cut' that breathes life, beauty and dazzling brilliance
into a diamond. The three diamonds shown below are all SI2 Clarity and
G-H Color, but there is a big difference in their appearance, due to the
quality of cut.
 |
 |
 |
SI2 Clarity, G-H Color, Fair Cut
(A deep cut usually makes
the diamond appear dark) |
SI2 Clarity, G-H Color, Very Good Cut
(A proper cut unleashes the
fire and brilliance within a diamond) |
SI2 Clarity, G-H Color, Fair Cut
(A shallow cut usually makes
the diamond appear opaque) |
If cut is so important, why aren't all diamonds cut to a superior standard?
Both the cutter and the seller usually have a strong financial incentive
to offer diamonds with inferior cut. When a rough diamond is cut
to superior standards, about 50% of the stone's original weight
can be wasted in the process. By cutting a diamond that is too deep
or too wide, the same piece of rough yields a diamond of greater
carat weight. Unfortunately, these diamonds are dull, milky, or
dark in appearance.
 |
 |
This 1 carat rough can yield a
.50 carat diamond with excellent cut and
extraordinary brilliance, dispersion and scintillation, or... |
The same 1 carat rough can yield a
.75 carat diamond with fair cut
that is dull and milky in comparison |
The mathematical formula for a round diamond works like this: for a cut
with exceptional brilliance (rated "very good" or better), the
depth of the diamond will measure between 57% to 65% of the total diameter.
In other words, a 1 carat diamond that is 6.5mm wide and 3.9mm deep will
display an exceptional return of light to the viewer's eye.
Our
Mountings:
MiaDonna Diamond Hybrid uses the same settings you would find the finest
earth mined diamonds set in. We use the same solid 14k gold, 18k gold,
palladium or platinum for its magnificent settings that you will find
in jewelry costing 4, 5 and even 6 figures. We do not use plating over
brass or steel that will wear off. You will always feel proud showing
off your MiaDonna Diamond jewelry, receiving compliments galore. MiaDonna
Diamond Hybrids are of the highest quality. All our side diamonds under
.25ct are set with natural diamonds.
