The 4C's Explained

Avital & Co.

If you can imagine it, we’ll create it since 1957

Diamond Cut

The first of the 4C's that Avital and Co., located in the heart of the world famous Diamond District in New York City (NYC), recommends you should take into consideration when looking to purchase your diamond is the cut. The reason for this is that the cut of the diamond has the greatest influence over the beauty of your diamond and will determine what we refer to as sparkle.

 

Diamond Cuts

 

The cut of the diamond is in reference to the diamond's balance of symmetry, proportion, and polish, which is achieved by the diamond cutter. When your diamond is ideally cut, the diamond will shine and sparkle because the cut allows the light to travel through your diamond and exit in an heirloom radiance of a colorful rainbow. If the diamond is cut too deep, light escapes out the side of the diamond and if cut to shallow, light escapes out the bottom of the diamond. Both of these poor cuts will cause the diamond to appear dull, lifeless and thus will not have a radiant sparkle.

The cut also determines the shape of the diamond. The most popular shape is called round brilliant. Other diamond shapes are asscher, emerald, oval, marquise, pear, radiant, princess, heart, cushion, baguette, and trillion. Some of the less popular diamond cuts are bullets, trapezoid, and half-moon. Click Diamond Shapes and Cuts for more information.

All of the diamonds that Avital and Co., located in the heart of the world famous Diamond District in New York City (NYC), acquires are carefully selected by our trained gemologists to emphasize the brilliance of your diamond.

Diamond Color

Color is the next important characteristic that you should look for when purchasing your diamond.  The color of a diamond refers to the lack of color that is found in the diamond grading and is based on the whiteness of the diamond.  Due to natural traces of nitrogen that are present in a diamond from being formed under the Earth's crust, most diamonds exhibit slight hints of yellow, brown, or gray.  For this reason, a diamond's color is graded on a scale from D-Z.  The less color that is visible to the naked eye, which allows more light to pass, the higher the letter the diamond is given and thus making it more valuable.  So a diamond that is graded from D-F is considered colorless, G through J are considered near-colorless, K through M are faint, and N through R are very light, and S-Z are referred to as light yellow or brown.

Diamond Clarity

Diamonds are the result of carbon exposed to extreme pressure and heat deep within the Earth's crust. Consequently, most diamonds have tiny imperfections, which are called inclusions or flaws and blemishes. Clarity of a diamond refers to the absence of inclusions and blemishes within the diamond itself.  Most of these imperfections are not visible to the naked eye.

To judge the clarity of a diamond, gemologist will examine a diamond carefully using a lens with a magnification of 10 x.  The diamond should be loose and not in any type of setting.  They will then judge the clarity of the diamond using five clarity factors: size, number, position, nature, and color or relief.  The clarity grade is assessed based on the most noticeable inclusions, the so-called "grade setting inclusions.”[1]

Once these clarity factors are taken into consideration, gemologists use the following scale to assign the clarity quality of the loose diamond stone:

Diamond Carat Weight

The way gemologist measures a diamond is called a carat.  Carat weight is often confused with the visual size of the diamond even though it is actually a measurement of weight.  This small unit of measurement is equal to 200 milligrams.  When considering the diamond size, Avital & Co., located in the heart of the world famous Diamond District in New York City (NYC), recommends that you look at two other factors:

  • the diamond's cut grade
  • the distance across the top of the diamond measured in millimeters.

The reason why Avital & Co., located in the heart of the world famous Diamond District in New York City (NYC), recommends this is because how you will view your diamond is by looking at it from the top.

After the other 4C's have been ascertained, the carat weight of a diamond can be easily established to fit within your budget.  Due to the fact that larger diamonds are more rare, the larger the carat, the more expensive the diamond.  For example, a 1.00ct diamond could cost 4 times more than a 0.50ct diamond.

When cutting a raw diamond, a diamond cutter uses “magic numbers” (as they are known in the industry) or cutoff weights.  The diamond cutoff weights are 0.50 ct., 0.75 ct., 0.90 ct., 1.00 ct., 1.50 ct., and 2.00 ct.

When you purchase your diamond engagement ring or diamond wedding band, the jeweler will refer to the weight of the ring in total carat weightThis phrase represents the complete weight of all of the diamond stones in the ring including the setting and the center stone.  For example, a diamond engagement ring that has a 1.50ct center diamond stone and 0.50ct side stones will have a total carat weight of 2.00ct. Click Diamond Carat Weight Table to see a comparison of the various shapes and cuts of diamonds.  

We here at Avital and Co., located in the heart of the world famous Diamond District in New York City (NYC), want to stress to you the importance of all of the 4C's when choosing your perfect diamond. What determines the value of your diamond is the combination of the 4C's. After making your appointment, one of our gemologist will help you decided which diamond stone is perfect for you based on these qualifications and on your budget.
