Education - Cut
Cut has the biggest impact on the beauty
of diamonds and the least amount of difference in their price. The word cut has
several meanings when it comes to diamonds. The cut of a diamond does not just
mean its shape (round brilliant, princess, oval, cushion, etc.) but also addresses
the symmetry, polishing, angles and the proportions of each physical aspect of
The cut determines the diamond's sparkle. A properly cut
diamond will refract the light that enters the diamond and return it through the
top to produce the much desired sparkle. The angles have to be exactly right to
effectively reflect the light back to your eye.

Education - Carat (Weight)
The weight of a diamonds is generally
given in carats. The term carat originated in ancient times when gemstones were
weighted against the carob bean. Each bean weighed about one carat. In 1913, carat
weight was standardized internationally and adapted to the metric system. One
carat equals 0.2 grams - a little more than 0.007 ounce. In other words, it takes
142 carats to equal 1 ounce.
Two terms, carat and karat are often confused.
Karat refers to the fineness of gold alloys (pure gold is 24 karat; 14 karat is
14 parts gold and 10 parts other metals) and carat refers to gem weights.
weight of small diamonds is frequently expressed in points, with one point equaling
0.01 carats. For example, five points is a short way of saying 5/100 of a carat
and fifty points equates to a half carat.

Education - Color
Diamonds are found in a variety of colors, but chances
are all the diamonds you'll see in your shopping will be white or yellow, and
the whiter the better. The yellow color in diamonds comes from trace amounts of
nitrogen. One part in a million will cause a yellow tint to appear in the K color
diamond. As a rule, the more yellow the stone, the less value it has. There's
a good reason for this. The yellower the stone, the less sharp and sparkly it
appears. A whiter stone lets greater amounts of light pass through it, making
it sparkle and shine.
Keep in mind that the color illustrated on these
color charts is exaggerated in order to see the difference on your computer monitor.
Actual color differences are much more subtle.

Education - Clarity
Virtually all natural diamonds contain identifying
characteristics, many of which are invisible to the unaided eye. Clarity is the
degree to which a stone is free from external marks called blemishes and internal
features called inclusions. Inclusions normally have a greater impact on grade,
value, beauty, and durability than do blemishes.
When shopping for a diamond,
the goal is to decide what level of these imperfections is appropriate for this
particular purchase. A certain level of imperfections can be to your advantage
since they act as a fingerprint to help identify your diamond. These imperfections
can lower the price of the diamond to make it affordable without affecting its
beauty to your eye.
