Know the Color, Clarity, Cut, and Carat Weight of Diamonds:

1. Diamond Color Actually Means Lack of Color

A diamond with no color, like a drop of water, is valued higher than a diamond with some color. All diamonds are evaluated, from D (diamonds with no color) to Z (diamond with color).

A diamond expert, under controlled lighting, compares the diamond to “master-stones” to determine the absence of color, and gives the diamond a rating.

2. Diamond Clarity

Diamond Clarity refers to the absence of “inclusions” (substances, spots, etc. included in the structure of the diamond) and “blemishes” (external characteristics).

Diamonds are created under pressure and heat, and therefore have both inside and external characteristics that need to be evaluated by size, nature, position, and relief. The question is how do they affect the appearance of the diamond? The purer a diamond is, the better the Clarity.

Clarity is appraised after looking at the diamond under powerful magnification, and then determining what inside characteristics it has (inclusions). Then a Diamond Clarity Scale is used to give the diamond an overall clarity rating.

3. Diamond Cuts

Knowing how your diamond is cut is essential in knowing your diamond and its value and ability to transmit light and sparkle. There are diamonds cut round, heart-shaped, oval, marquise, and pear. A skilled gem cutter will know exactly how to cut a diamond, so it interacts with the light to enhance its beauty and value.

4. Carat weight

By using 200 milligrams as a “carat”, the weight of your diamond can be given within a hundredth decimal place. Larger diamonds are rarer, and thus more valuable and desirable. Remember that the value of a diamond is not only its weight, but also its color, clarity, and cut.
