Diamonds
The 4 C’s of Diamonds
Cut
Cut is the most crucial of all the variations
that affect the diamonds beauty and value. The
make, or cut or a diamond refers to its proportions
which influence the brilliance the diamond radiates.
We have a sarin machine that measures the exact
cut of the diamond.
Color
Color is the most difficult characteristic to
judge and should be done by a graduate gemologist
using his or her expertise as well as the latest
technology. The purest color in a diamond is no
color at all. They range from colorless to almost
every hue with the majority containing some tint
of yellow. We have a GIA machine, the colorimeter,
which measures the exact color of a diamond.
Clarity
To determine the clarity of a diamond, a 10 power
magnification device must be utilized by a skilled
diamond grader. The finest clarity is one that
is free or internal or external blemishes or inclusions.
Minute inclusions do not diminish the beauty but
lower the cost of the diamond; while larger inclusions
can obstruct the passage of light making the stone
worth less.
Carat Weight
The weight of a diamond is measured in carats.
One carat is divided into 100 parts or points.
Example: 1/4ct. = .25ct.
1/2ct. = .50ct.
3/4 ct. = .75 ct
The
weight of a diamond is the easiest to determine.
When multiple diamonds are used in jewelry items,
the weight is expressed as total weight (tw).
We also have a GIA approved scale that measure
the exact weight of a diamond.
