Carat Weight: |
|
 |
Carat is the term used to describe the weight of any gemstone, including diamonds. Diamond weights are stated in metric carats or “ct” (versus the karat amount of gold contained in an item). Since 1913 the international standard has been 1 carat = 200 milligrams, or 1/5 of a gram. In jewelry pieces with more than one diamond, the carats may be described in terms of total carat weight (TW). This number is the combined total weight of all stones in the piece. |
Clarity: |
|
 |
Most natural diamonds contain identifying marks known as inclusions, many of which are invisible to the naked eye. Diamonds having fewer and less noticeable marks are rarer and command higher prices.

Cut: |
|
 |
Quite often the cut of a diamond is confused with its shape. Diamonds are cut into various shapes depending upon the original form of the uncut diamond, which is referred to as “rough.” Whatever the shape, a well-cut diamond is better able to reflect light. The Cut refers to the proportions, finish, symmetry, and polish of the diamond. |
Colour |
|
 |
Most diamonds appear colorless but actually have slight tones of yellow or brown. Diamond color is graded on a scale of D (colorless) to Z (heavily tinted), and the closer a diamond is to being colorless, the more valuable it is. Even when a diamond has a visible tint such as K or above, it can still be beautiful if it has good clarity and cut. |
