Diamond Color Chart |
| When we speak of grading a diamond for color we mean deciding by which
amount the diamond's "body color" deviates from the whitest possible
(water like colorless) color. |
|
| It is difficult to see the subtle differences between one color grade to
the next. When grading diamonds for color it is important to have a
Master Color Diamond Set (pre-graded diamonds usually E-G-I-J) to
compare the diamond being graded. Also a controlled lighting environment
is helpful for accuracy. Diamonds must always be graded unset to
ensure grading accuracy. |
Diamond Clarity Chart / Scale |
| Most diamonds aren't perfect and include blemishes, inclusions, or
feathers naturally created through time. The clarity of a diamond refers
to how clean or clear a diamond is internally. The cleaner the diamond,
the higher the price. The clarity scale was developed to have a
universal rating system of diamonds imperfections. |

Diamond Carat Weight Chart |
| Diamonds are measured by carat weight, and not size. Two diamonds having
the same carat weight could have different millimeter sizes because a
diamond is three dimensional meaning length, width, and depth. The
scale below is a comparison of the sizes based upon carat weight with
cutting percentages being the same. |

Diamond Shapes |
To most people, the word 'diamond' conjures images of the ever-popular
and always classic round stone. Going this route is almost guaranteed to
get you the reaction you're looking for, but you can also choose one of
the more unique shapes collectively referred to as 'fancy cuts'.
Shape does not affect the quality of the stone. If it is well cut its
brilliance and value will endure no matter what. The shape of the rough
diamond crystal usually dictates the shape of the stone. All are cut for
maximum fire and brilliance, but facet shape varies with the cut and as
a result, filters light differently. Additionally, some designs are
more suited to a particular shape. |

Diamond Cut |
| The cutting of a diamond and its proportioning, called "Make" in the
jewelry trade, are of extreme importance. The fire (variety and
concentration of the prismatic colors emitted) and the brilliance
(liveliness or sparkle, of the diamond) directly depend on the proper
cutting and proportioning of the diamond. Obtaining the optimum Table
and Depth proportions are critical for superior diamonds. "The Magic is
in the Make!" |

Diamond Anatomy |
| To obtain a "High Performance" diamond it is helpful to have a clear
understanding of a Diamond's Anatomy. With a clear understanding of the
Diamond's Anatomy and the proper proporations for Ideal Makes one can
be assured a "High Performance" diamond will be yours. |
