Selecting Diamonds

Diamonds are graded for certification by

laboratories using grading criteria. Four of

these criteria are critical to understand when

making a diamond purchase or investment.

Known as the “Four C’s” these criteria are:

color, cut, clarity and carat.

Color is the result of the composition of a

diamond and it does not change. When a

jeweler is describing the color of a diamond

they are referring to the presence or absence

of color in white diamonds. Because a

diamond with no color allows maximum light

to pass through, colorless diamonds are

preferred for their sparkle.

Cut refers to a diamonds reflective quality.

Most diamonds are cut with 58 facets. The

brilliance of diamonds is heavily dependent

on the cut. The different angles and the finish

of a diamond determine its ability to reflect

light and cause its brilliance and fire.

Remember that the cut of a diamond can

have an impact on its durability as well as its

beauty. Some cutting faults can make a

diamond prone to breakage. A diamond

that is cut too thin can also cause light to

leak out of the back and the diamond will

lose some of the sparkle and appear not

to shine. So, as you can see the Cut is

probably the most important of the Four C’s.

During the formation process, inner flaws, or

inclusions occur in most diamonds. The

number and size of these inclusions

determine what is referred to as the clarity

of a diamond. Diamonds that are clear

create more brilliance and therefore are rarer

and highly priced. To be considered

“flawless”, a diamond must have no surface

or internal imperfections visible upon being

viewed by a skilled diamond grader using

10 power magnifications.

Carat is the unit of weight by which diamonds

are measured. One carat is equal to 200

milligrams. A carat is divided into 100

segments called points. 150 points would

equal one and a half carats.

When you go to the store to make that all

important diamond purchase, do not be shy!

Ask questions, get the answers needed to

make an informed purchase. Shopping for

certified diamonds enables you to make an

informed selection. Knowing the “four C’s”

allows you to comparison shop and purchase

the best diamond at a fair price. But, before

making a purchase, shop around and decide

what shapes and styles really appeal to you.

Enjoy your diamond for years to come!
