 The
Isee-2 is an innovative tool of patented* technology and design
that enables an objective evaluation and comparison of diamonds.
At Rodriguiz's House of Stones we can let you see for yourself
the true beauty of a diamond.
This unrivalled instrument gives the potential buyer of a diamond
a "technical" eye to compare different stones, much
in a way only a trained diamond professional could otherwise
do.
Taking 180 photographic views of a diamond, it will objectively
evaluate the brilliance, scintillation and symmetry of any round
brilliant diamond. In this way it will scan two stones consecutively
and project their images and respective "scores" on
a computer screen, making is easy to compare and see what a
diamond is all about.
The Isee-2 intrinsically focuses on the visual impression of
a stone, its pure beauty provided by the quality of the make.

The 4 Cs
The Gemological Institute of America (GIA) has established
a criteria in determining the quality and value of a diamond
commonly referred to as the four C's - Cut, Color, Clarity
and Carat weight.
Cut
Many people confuse cut with the shape of a diamond. The shape
you select is a matter of individual taste, and today your
choice is only limited by the skill and imagination of the
craftsman. The cutting grade is determined by their effort
to maximize the refraction of light during every stage of
the fashioning process. Most brilliant-cut or fancy-shaped
diamonds possess 58 carefully angled flat surfaces, called
facets, whose placement will affect the fire, brilliance and
ultimate beauty of your diamond. The value of two diamonds
with exactly the same carat weight could vary by 40% depending
on the quality of cut. The highest grade is the ideal cut.
Color
The most prized diamonds are colorless. Their beauty depends
entirely upon their remarkable optical properties. All the
colors of the rainbow are reflected back to your eye. Though
most diamonds appear to be icy-white, the fact is that most
diamonds have slight traces of color, usually yellow or brown.
The most valuable is no color, or colorless, due to its rarity.
With each subtle departure from colorless, there is a decrease
in rarity and value. The GIA color grades range from D (colorless)
all the way to Z (yellow-brownish).
Clarity
Clarity in a diamond is defined by the presence of natural
characteristics. A diamond is graded using a microscope at
10 power (10x) magnification. The most rare and valuable diamonds
have no natural characteristics at 10 power, and diamonds
with more and larger characteristics are less rare and less
valuable. As with color, differences in clarity can be very
subtle, yet have a decided impact on value.
Carat Weight
Carat weight is the standard unit of weight for diamonds.
One carat equals 1/5 of a gram, or .007 of an ounce. Carat
weight is further divided into decimals. For example, exactly
1/2 carat is .50 carat and expressed as 50 points. Because
diamonds are weighed to hundredths of a carat, they must be
weighed on extremely precise and sensitive scales. All other
factors being equal, as weight increases, so does rarity and
value.
