Diamond Cut

A diamond cut is one of the "four Cs" used to determine the overall quality, and thus the price of the diamond. Most diamond certificate will include the evaluation of diamond cut, and all other things being equal, a diamond with a better cut grade will command a higher price.

while the other three criteria (clarity, color and carat weight) are relatively easy and simple enough that they can understand and evaluate anyone, the cut is much more complex variables.

Methods for determining diamond cut ratings can vary depending on who is making the assessment, and, further complicate things from a customer perspective, some certificates can not explain many details of which criteria are used to cut ocjenudijamant.

That being said, if you're thinking about buying a diamond, it would be well worth the time it takes to understand what different cut grades mean, how they are determined, and what they impact on diamond prices. This knowledge seems to be better able to determine for themselves what the diamond price should be, vary a good deal with a bad one, and make the best possible investment when buying diamonds.

What is a diamond cut?

In simple terms, reduce the level of a diamond refers to the "light show" of a diamond, or the degree to which a diamond reserves and reflected light that enters. diamond with a good cut will be very reflective and exhibit the best possible amount of sparkle. Also, the diamonds that "leakage" of light through the bottom or side are usually cut too shallow or deep, ie, they thus will have less favorable cut class.

Since it is widely recognized that mention or gloss is what gives a diamond its unique splendor of beauty, it follows that the cut is what separates the finest diamonds from just ordinary themselves.

It should be noted that the "cut" in this sense does not refer to the desired shape of a diamond. If you've ever browsed for diamonds, you've probably come across terms such as "Princess Cut", "Asscher cut, Emerald cut, " and so on. This applies only to the stylized diamond shape, not cut indication visitors.

The diamond cut grades are there?

At this point is still not standardized systems for diamond cut grade. Each certification body uses its own system to rate cut diamond, which can make things a little confusing. Fortunately, however, the ratings themselves are usually pretty self-explanatory, even if the methods used to determine them are not all that clear (more on that later ).

Most certification to use five or six-point cut grading system. typical system goes like this, the best to worst:

Ideal diamond with maximum brilliance.
Premium: Almost the same ideal.
Very good diamond with a little light leakage.
Good diamond with a decent reflectiveness, usually one that is cut to size, rather than gloss.
Fair or Poor: Diamonds that reflect relatively little light

.

Again, however, in some cases, the terminology used can vary, the Gemological Institute of America, one of the main diamond rating authorities, for example, assessment of diamond cuts, as well as excellent, very good, good, fair, and Poor, thus, the diamond cut rated "excellent" by GIA will be roughly equal to those rated "ideal" other bodies. In addition, some diamond suppliers have a special name for their best cut. For example, online diamond retailer Blue Nile is the "Blue Nile Signature ideal" cut, a term used to denote reduced within the first 1 %.

How do I cut diamond ratings assigned?

This is where things start to get complicated. The methods used to quantitatively assess the quality of cut vary. how GIA diamond cut determines the grade should be, for example, differs in very specific ways of how the other for certification as an AGS to do. In most cases, these organizations do not reveal specific information about the processes used.

diamond shape also makes a difference with regard to how to reduce his class was determined. Although there are some basic criteria remain the same for any type of diamond, the exact methods used for evaluation round cut diamonds are different from those used for the assessment of heart-shaped diamond cut. The remainder of this explanation will focus on round diamonds, because it is by far the most common form of diamond.

One of the factors that influence the degree of cut round diamond is the number of facets. Facets are flat, defined areas on the surface of the diamond. facets on the round diamonds are usually triangular. Currently, it is thought that the ideal round diamond should have 33 facets on the crown (see diamond that sits above the belt, which is itself the widest point of the diamond) and 25 on the pavilion (lower part of a longer diamond ).

When there are irregularities on the surface of a diamond cutter can add additional aspects to overshadow them. This results in a degradation in overall quality of cut.

While the facet count is generally agreed upon as a good way of assessing the quality of the diamond cut, there are other points where gemologists often disagree. Some of the other factors used by some authorities to determine the lower grades include a diamond crown height, pavilion depth, diameter of the table (on top of the crown) and crown and pavilion angles.

benchmark American Standard calls for a circle of diamonds for the crown height of 16.2%, pavilion depth of 43.1%, a table diameter of 53% of the total zone diameter. Brilliant Ideal measurement, however, calls for 19.2% of crown height, pavilion depth of 40% and 56.5% table diameter. While these differences May be difficult for amateurs to tell, they are a good illustration of the difficulties associated with creating a simple assessment of diamond cut.

Although there are some disagreements as to the exact proportions that make the perfect cut diamond, diamond for potential buyers, the most important thing to understand is that the diamond certification by an organization like AGS and GIA were true and meaningful. Reputable diamond suppliers base price at which buy and sell diamonds on the cut as the rest of the "four Cs." When buying a diamond, you need not worry about the perception of what makes a good diamond cut is changed so that the value of your diamond will be significantly affected.

Which diamond cut grade represents the best value?

kind of diamond is best for you depends largely on your budget. For customers who are willing to buy them, sellers usually recommend diamonds with the highest grades can be reduced. However, this May be due to some self-interest on their part.

the other three Cs have an impact on diamond prices as well, so it can be difficult to measure the exact difference in price between an ideal or excellent cut diamond and a very good cut. To the casual shoppers and budget-conscious investors, diamonds with very good or good cut grade can represent excellent value. This is because, while they may be more affordable than otherwise equivalent to an ideal or excellent cut diamonds, visible difference in quality is minimal.

At the same time, feel free to use your own discretion. If, for example, visitors can find an ideal cut diamond that has good ratings in other categories, but still within your budget, then you should definitely take into consideration, as long as you are dealing with reputable manufacturers.
