Four Factors – Known As The Four Cs Affects The Value Of Every Diamond:
- Carat Weight
CLARITY of Diamonds:
The Four C’s of Diamond Value, A stone’s relative position on a flawless-to-imperfect scale. Diamond clarity is a qualitative metric that grades the visual appearance of each diamond. The fewer inclusions and blemishes the diamond has, the better the clarity grade.
Clarity characteristics are classified as inclusions (internal) or blemishes (external). The size, number, position, nature, and color or relief of characteristics determine the clarity grade. Very few diamonds are flawless, that is, show no inclusions or blemishes when examined by a skilled grader under 10x magnification. If other factors are equal, flawless stones are most expensive.
Grading color in the normal range involves deciding how closely a stone’s body color approaches colorlessness. Most diamonds have at least a trace of yellow, brown, or body color. With the exception of some natural fancy colors, such as blue, pink, purple, or red, the colorless grade is the most valuable.
Diamonds come in all colors of the spectrum. The prime color you see in a diamond is yellow, which is caused by the trace element nitrogen.
The proportions and finish of a finish of a polished diamond (also called make). The cut can also mean shape, as in an emerald cut or marquise cut. The Proportions are the size and angle relationships between the facets and different parts of the stone.
Of all the 4Cs of diamond value, Cut has the greatest effect on a diamond’s beauty. A good cut gives a diamond its brilliance, which is that brightness that seems to come from the heart of a diamond.
Finish includes polish and details of facet shape and placement. The cut affects both the weight yield from the rough and the optical efficiency of the polished stone; the more successful the cutter is in balancing these considerations, the more valuable the stone will be.
Carat is a unit which measures the physical weight of a diamond. The more the weight of a diamond the more will be its value and price.
The metric carat, which equals 0.200 gram, is the standard unit of weight for diamonds and most other gems. If other factors are equal, the more a stone weight, the more valuable it will be.
