Diamond has remarkable optical characteristics. A diamond
has four characteristics, known as the 4 C’s – Cut, Colour, Clarity and Carat
Weight. Color: With the exception of "fancy colored diamonds", the
more colorless a diamond is, the more valuable it is. Jewelers grade diamonds
on a scale from D (colorless) to Z (light yellow). Anything more yellow than D is
considered fancy and is much more expensive. Cut can be something very
difficult for a layperson to evaluate, which is why it is important to get an
AGS Certificate or a GIA Certificate verifying the quality of your diamond.
Cut is graded Ideal, Premium, Very Good, Good, Fair, and
Poor.Clarity: Diamonds frequently have inclusions, or small flaws, air bubbles,
scratches, or other minerals inside the diamond. The less inclusions a diamond
has, the more valuable it is, and the more beautiful it is. Some indicators that
lowers a diamond's value are when the diamond is not natural such as heat or
clarity enhanced or synethic. When the polish and symmetry grades are lower
than 'very good' and when the diamond has optically imbalanced proportions such
as the sum off all parts does not equate to the total depth.
