It is a useful tool to have as even having a ball park price for a diamond is better than going shopping without any idea whatsoever.
Look at it as providing an average price range for the diamond you are looking for.
Below are the parameters used to determine diamond prices internationally
Diamond carat weight is the measurement of how much a diamond weighs. A metric “carat” is defined as 200 milligrams.
A carat can be subdivided into 100 “points”. This allows measurements to a hundred decimal place. A 0.75 carat diamond can be described as a “seventy-five pointer”
Diamonds that weigh more than 100 points are expressed in carats as 100 points = 1 carat.
The “color” of a diamond refers to its degree of “yellowness.” The ideal diamond is completely colorless, and therefore it will be the most expensive. Many systems have been used to grade diamond color alphabetically from D (totally colorless) to Z (yellow) .
- D (Colorless) – Highest color grade your diamond can achieve. This color emits unequaled brilliance, and is highly sought after thus most expensive.
- E (Colorless) – Containing minute traces of color. Emits unsurpassed brilliance, and is quite rare but slightly cheaper that the D color above.
- F (Colorless) – Minute traces of color can only be detected by a trained gemologist. This is a high-quality color grade & still on the costly scale.
- G, H (Near Colorless) – Noticeable color only when compared to higher color grades. Excellent value, as it appears colorless to the untrained eye. This grade is more affordable as its more common than the top three D, E and F
- I, J (Near Colorless) – Slightly detectable color. Excellent value, as it appears colorless to the eye. At this color grade, you can get some very good deals without seeming to cut corners. Diamonds at this color grade seem white to the naked eye.
- K, L, M (Faint Yellow) – Faint color noticeable to the naked eye. Even with the presence of color, diamonds can emit fire & are beautiful especially when well cut.
Clarity is a measure of the number and extent of the flaws in the diamond.
Generally speaking, the fewer the flaws, the more valuable the diamond.
Clarity can also refer to the presence of identifying marks on & within the diamond.
Diamond clarity is obtained using 10X or a ten power magnification as most inclusions are invisible or not easily visible to the naked eye.
There are eight common diamond cuts or shapes that are offered by fine jewelers: These are Round diamonds
Heart shaped diamonds, Oval diamonds, Princess cut diamonds, Pear shaped diamonds, Emerald cut diamonds, Marquise cut diamonds and asscher cut diamonds.
Historically, the most popular diamond shape has been the round or brilliant cut diamond shape.
This is due to is amazing symmetry that causes the most amount of fire to be displayed in the diamond.
