The 4Cs of diamond quality are currently the universal method for evaluating the quality of any diamond, anywhere in the world. The Diamond 4Cs tell you two very important things: Diamond customers should now know precisely what they are purchasing, and diamond quality should be communicated in a universal language. We want you to know everything you need to know to make the best choice because we are your personal diamond dealer.
A gem-quality diamond's color is determined by its lack of color, like a drop of pure water. Diamonds with less color will have a higher value.
A D-Z scale was developed by the GIA and is most commonly utilized in the jewelry industry. The scale begins with the letter D, which is considered colorless, and increases in color presence until it reaches the letter Z. Because many of these color distinctions are so subtle, a skilled eye (an experienced gemologist) and a set of master stones are required to determine the color.
The simplest definition of diamond fluorescence is the effect that ultraviolet (UV) light has on a diamond. Precious stones in the D to H variety will range in pale blue fluorescence. These diamonds may have a bluish fluorescence, according to some, but only if the fluorescence intensity is extremely high is it considered a lesser quality diamond. However, not all diamonds with a very strong bluish fluorescence appear hazy, and they may fetch a lower price than diamonds without blue fluorescence. A diamond with fluorescence will typically be sold for 5% to 10% less than a diamond without fluorescence. It is essential to know that the color grade is accurate due to the substantial value difference between colors.
The process by which the element carbon undergoes extreme heat and pressure deep within the earth results in the formation of natural diamonds. Internal characteristics known as "inclusions" and external characteristics known as "blemishes" may emerge as a result of this process. The GIA developed a scale consisting of six categories, some of which were subdivided into 11 distinct clarity grades.
As the majority of people will not be able to see some of the inclusions or flaws without magnification, you will need an experienced jeweler to accurately determine this grade. We will take into account the diamond's size, characteristics, and how they affect the stone's overall appearance. While no diamond is completely pure, the closer it is, the more valuable it is.
This may be argued by many to be the most crucial aspect when purchasing a diamond. Cut is more about how well a diamond's facets interact with light than it is about the shape of the diamond. Although all diamonds will have some "sparkle" due to their faceted nature, the better the cut, the more sparkle a diamond will have. To create a stone with the proportions, symmetry, and polish that produce the magnificent return of light that is only possible in a diamond, precise art and craftsmanship are required. It is the most complicated and technically challenging of the four Cs to analyze.
Seven distinct categories are evaluated by the GIA Cut Grading System. The diamond's face-up appearance is taken into consideration by brightness, fire, and scintillation. The additional four: A diamond's design and craftsmanship are evaluated based on its weight ratio, durability, polish, and symmetry.
- Brightness: A diamond's internal and external reflection of white light.
- Fire: the dispersion of white light into all of the rainbow's colors.
- Scintillation: The pattern of light and dark areas created by reflections within a diamond and the sparkle it gives off.
Weight in Carats: The weight of a diamond is determined by its carat weight. 200 milligrams is the definition of a metric "carat." 100 "points" can be assigned to each carat. Measurements to the hundredth decimal place are possible thanks to this. A diamond's weight below one carat can be determined solely by its "points" by a jeweler. For example, we might say a jewel that weighs 0.25 carats is a '25 pointer.' Carats and decimals are used to describe diamond weights greater than one carat. The phrase "one point oh eight carats" applies to a stone that weighs 1.08 carats.
To obtain precise weights, loose diamonds are typically weighed using electronic carat weight scales. At the point when jewels are set, we can determine the diameter and depth of a stone using a mathematical formula that will give us the approximate weight.
All other things being equal, the price of a diamond goes up with its carat weight because larger diamonds are rarer and more sought after. However, there are three additional aspects of the 4Cs that can have a significant impact on the prices and values of two diamonds of the same carat weight: Color, cut, and clarity. It's critical that a diamond's worth is determined using all of the 4Cs, not simply carat weight.
Because diamond grading is subjective, you might find that different jewelers give a stone a different grade, especially if it is in a setting. This could be caused by very subtle differences. If your diamonds weigh more than one carat and you want to know the grade, it might be worth it to get a GIA report done on the stone to get the best grade. These can only be done to loose stones, so you might have to pay to have the diamond removed and then reset again.
