Know What Makes A Diamond Unique

The 4 C's Of Diamonds

No two diamonds are exactly alike...that is why is it is important to understand how diamonds are classified. As you research your Superior Quality® and Superior Cut®.diamond purchase from Fink's Jewelers, you need to consider four major categories of diamond characteristics: These defining attributes are cut, color, clarity, and carat.

Cut

While shopping online or in-store for diamonds, most people use "cut" to reference the shape of the diamond (Round Brilliant, Marquise, Pear, Princess, etc.). When grading a diamond, however, cut is referring to the proportions of the diamond that define its brilliance and reflective qualities. The Gemological Institute of America (GIA) rates cut from excellent to poor. The art of skillfully cutting and polishing a diamond allows the maximum amount of light to be reflected and dispersed back through its top (crown). When a stone is cut too shallow or too deep, the light that enters through the top is allowed to escape through the diamond's bottom and does not allow the maximum beauty of the diamond to be realized. The allure of a particular diamond depends more on cut than anything else.

Color

The 4C's of Diamonds

Diamond color options cover a wide range of possibilities, but most shoppers are looking for diamonds in the "white" range. The Gemological Institute of America (GIA) rates white diamonds from D (colorless) to Z (light yellow). The best and most desired color is actually no color at all. A totally colorless diamond allows light to pass through it easily, and the reflected light is dispersed as all the colors of the rainbow. The differences from one grade to the other are very subtle and it takes a trained eye and years of experience to color grade a diamond.

Clarity

The clarity of a diamond is determined by the amount of flaws (inclusions), and where they are located, when the diamond is viewed under 10× magnification. The Gemological Institute of America (GIA) rates clarity in diamonds from Flawless to Imperfect 3. Due to the natural process of diamonds forming under the earth, every diamond has unique blemishes. No diamond is absolutely perfect under 10× magnification, though some diamonds so come close. Known as Flawless diamonds, these are exceptionally rare. Most jewelers have never even seen one. Using the GIA International Diamond Grading System™, diamonds are assigned a clarity grade that ranges from flawless (FL) to diamonds with obviousinclusions (I3).

Carat

Diamonds are weighed in metric carats. One carat is equal to 0.2 grams, which is about the weight of a paperclip. Two diamonds of equal weight can have very different values depending on the other members of the Four C’s: clarity, color and cut. Because even a fraction of a carat can make a considerable difference in cost, precision is crucial. In the diamond industry, weight is often measured to the hundred thousandths of a carat, and rounded to ahundredth of a carat. Diamond weights greater than one carat are expressed in carats and decimals.
