Knowing the 4 C's will help you make an informed decision about your diamond purchase. We at H&B Jewelry and Loan are dedicated to helping you make the best choice for your budget.
Cut: The cut of a diamond determines how it handles light.
Color: Good color is no color. From yellow to colorless diamonds.
Clarity: True clarity is a rarity. Inclusions are imperfections in the diamond.
Carat: Bigger is bigger, but that doesn't make it a better diamond.
The H&B Diamond Search Enigine can locate the right diamond for you using all of these characteristics.
Cut is a term which broadly refers to the shape of the diamond, and at a deeper level cut also refers to the geometry of the diamond, or the make. A diamond's only job is beauty, and the only thing it does to gain that quality is due to light optics, and the way the light travels in the stone. The combination of refraction and reflection produces an effect we call scintillation.
Diamonds are cut into a number of shapes, depending on the nature of the rough stone. A cutter will decide based on the quality of the crystal what shape will yield the greatest value and prize. The most popular shapes are round, marquise, oval, pear, heart and emerald, and the choice is largely a matter of personal preference. There are also wonderous new shapes which are sheerly beautiful as well, the radiant cut and the princess cut come to mind instantly. Whatever the shape, however, a well cut diamond is the work of a master diamond cutter. When cut to good proportions, the diamond is better able to handle light, creating more scintillation, more sparkle. And that's a great reflection on you.
How a diamond handles light:
It is the cut that enables a diamond to make the best use of light.
1. When a diamond is cut to good proportions, light is reflected from one facet to another and then dispersed through the top of the stone. This is a combination of reflection and refraction, where the light does not exceed the "critical angle", rebounds and exits via the crown. A very fine geometry also greatly increases the "masking effect" of activity within the diamond, and a lower clarity will appear much more "eye clean" due to the effect. My opinion is that the cut of a diamond is what drives the show, the geometry and the diamond's beauty are linked to the data and we can help you to get the best value and beauty.
2. If the cut of the diamond is too deep, some light escapes though the opposite side of the pavilion. This is where the critical angle between reflection and the light passing out of the stone is exceeded, and the effect is called "Unplanned Light Loss." This effect can really dim the beauty of the diamond, so do be aware that a well cut diamond will give you a dazzeling effect like no other gem can. Poorly cut diamonds are discounted greatly for their lesser appeal.
3. If the cut is to shallow, light escapes though the pavilion before it can be reflected. The AGS rates the ideal range for depth as between 58.5% up to 63%, and going below this in a round brilliant is not advised at all, the stone will become very dull and have the effect we call the "Fish Eye" effect. In essence, the light is lost out the back of the diamond, and remember a poorly cut diamond will easily be discounted 25% or more, so what seems a bargin can become an embarrasment.
One thing which bears mentioning is that different shapes will have radically different percentages and measurements. A princess cut might be 75% deep and have a 70% table and be a prime example of that shape. Trillions have a depth in the 30-40% range, and are picked for their brilliance and reflective qualities. We know that the world of diamonds can be a scary place for someone who wants to understand and we're here to help you do just that. We'll make the mysterious world of diamonds easy to understand, and we'll make finding that dream diamond a breeze. We're happy to help navigate with you...
The Diamond's Color
In most cases good color, is no apparant denegrating color.
Diamonds are found with a range of color, from faint yellow or brown through to the very rare pinks, blues, greens, and other colors known as "fancies". However, the best color of a diamond is no color, which is defined by a perfect "D" color. In practical terms the range for "Colorless" might best be defined as from "D" to "G" for Platinum, and where there is a yellow contrast in the ring, or colored gem, I think from "H" to "I" is a great range for eye popping white and bright. A totally colorless diamond allows light to pass effortlessly and be reflected and refracted into pinpoint rainbows of color. One might also offer that to give a woman such a diamond is to show your true colors as well.
The Diamond's Clarity
The Diamond's Carat
The Measurement of weight of the diamond.
This is the weight of the diamond measured in carats. One carat is divided into 100 "points", so that a diamond of 75 points weights .75 carats. This ancient weight has been used for centuries for diamonds, and has become the universal standard. I like to say about now that gross weight is one of the major factors for anyone choosing a fine diamond, but also one should never forget the geomery of the cut, and the beauty a well cut diamond unlocks by nature.
Carat-weight is the easiest of the 4 C's to determine. But two diamonds of equal weight can carry unequal value, depending on their cut, color and clarity. On the GIA certificates a notice informs that a poorly cut diamond can be discounted 25% or more, so be aware that weight is not the defining factor for picking your diamond.
Another thing to consider is that in a diamond which is cut too deep the diameter will be reduced. Many poorly cut diamonds are sold by others daily without explaining how attention to geometry in any given shape will always yield a better appearance and appeal
