Shape

Shape refers to the form a diamond.  The majority of diamonds are cut in the round brilliant shape, but some people prefer a more unique shape like a princess, oval or pear.  Each shape filters the diamonds light differently and has a unique appearance.

Color

Diamonds are all graded on the GIA color scale from D (colorless) to Z (yellow).  Diamonds on the ends of the spectrum are more expensive due to rarity.  Most people are looking for a diamond as close to colorless as they can afford.  Diamonds between D and E are all considered colorless and from G to J are considered near colorless.

Carat

Carat is the unit of measurement used for diamonds.  One carat equals 0.02 grams to 200 milligrams.  Carat weight is the prime factor that determines the weight of a diamond.  Carat weight makes expressing diamond weight easier than milligrams.  It's similar to pennies to a dollar, one hundred pts equal one carat.  The larger the diamond the more costly it is due to the rarity factor of larger diamonds, especially in better qualities.

Clarity

Almost all diamonds have imperfections.  The fewer the imperfections in  a diamond the more rare it is, therefore the more expensive it is.  One type of imperfection is called a natural.  Naturals look like crystals, some are dark and some are light in appearance.  The other type of inclusion is a feather, which looks like a crack or line.  The amount, size and location of these inclusions determine the value and clarity.  The Gemological Institute of America (GIA)  has determined a scale that ranges from F1 (flawless) to I3 ( many inclusions visible to the naked eye)

Cut

The cut is extremely important and usually the least talked about factor in diamond purchasing.  Only diamonds cut to the proper proportions will optimize their fire and brilliance.  Diamonds that are cut too deep will look dull because the reflection is leaked out the side of the stone. 
Diamonds that are cut too shallow loose light out the bottom and often appear dark.  Diamonds cut to the proper proportions are brighter and brilliant because the light entering the stone reflects and returns to your eye.  *Off-cut diamonds should be far less expensive.
