Diamond is a precious natural resource of the world the most part, not to mention one of the most desirable gems. Properties of diamond are natural products with a wide variety of, so that each diamond unique. The many possible combinations of these characteristics determine the quality and the value of a diamond. Recognizing the need for a universal system of classification of the GIA, the Gemological Institute of America is, as the whole worldmost respected Gemological Institute of Research has developed the four C. The four C's are cut, color, clarity and carat weight. The classification system internationally recognized diamond revolutionized the diamond trade and is now used worldwide by nearly all professionals and enthusiasts about the diamond. Since the individual diamonds vary so greatly in quality and price It is important for consumers to know the four C's, too.We have the basis of this classification system as outlined below, to help consumers by requiring them to make educated purchases.
Cut
The cut of a diamond can be one of the most important C, four diamonds and can improve the overall quality, value and beauty of this. There are many different sections, each following a specific effect on the three characteristics:
* Light – the amount of light reflected the diamond
* Fire – the various Colors of the spectrum that gives a diamond
* Scintillation – the sparkle and brilliance that moves generated when a diamond is
In a well-cut diamond, light enters and the table (top flat facet) travels through the pavilion, which is reflected and scattered by the corona, which is a desired effect. Unfortunately, a poorly cut diamond, the more light is emitted by the belt, which dramatically reducessparkle> Diamond.
The quality of a diamond cutting is another based primarily on symmetry and polish, and the odds on table size, crown angle and the depth of a pavilion. In most cases, more facets of a diamond is, luster and brilliance, most will. But the depth of the pavilion has a great influence on this. If the depth of the pavilion is either too bright or too little can be lost, rather than from the pages of Stoneaddressed by the Crown.
The diamond is round brilliant cut diamond is by far the most common, although many others are gaining popularity. The round brilliant cut diamond specifically designed for use, and pay the 57-58 well proportioned facets, brilliance and luster is more evident than on most sections. But with so many variations of diamond cuts, many possible combinations of units are directly affects the beautya diamond, and therefore the value.
Color
Similar to the cut of a diamond, the color can increase or decrease the sparkle and fire. Obviously, with less color diamonds reflect light better than those with just a yellow or brown gradient. This, coupled with the fact that nature has to offer, and of these less colorless diamonds, which makes them valuable and sought after.
Again see the need for a universal system, GIAdeveloped the diamond grading color scale, the letter d, which are generally accepted today. at the Diamond, conditions gradually with specific ads are often only compared to diamonds of known color paint can guarantee very little difference in A. A diamond is missing is the color of class "D" and the more color a diamond has, the farther you travel along the cut material alphabet. Diamond with a degree of 'Z' stands foryellow or brown, and therefore does not reflect light and a colorless diamond. Fancy colored diamonds, although most improved irradiated and color, not with this grading scale, and are often more important than when naturally colored, are extremely rare.
The most common types are colored G to I, as so often in nature, and are much more affordable. Although the color of the diamond have the qualities of this tip is not usuallynaked eye and inexperienced. Similarly, J M rated diamond can have a very weak yellow color, the right piece of jewelry and diamond cut, color seems less obvious (though hard to start). platinum or white gold settings generally require higher diamond grade, and a value in gold is the yellow of a lower grade diamonds.
Most jewelers use of the GIA Diamond Color Grading Scale [out]and it is recommended that customers should do the same in order to better understand the subtle differences in color of a diamond can, and to better assess the quality and value of a diamond.
Clarity
After the GIA, "Diamond clarity refers to the absence of internal inclusions or external blemishes. Of all the characteristics of the diamond can clarify the value of the largest impact on how perfect diamond diamonds are a rare Sunnatural diamonds produced in the earth under extreme pressure, yet it is not surprising that almost all diamonds have flaws low. There are two types of errors – errors and inclusions. Defects are defects on the external surface of a diamond, and includes chips, dents and scratches, most of which occur during cutting. Inclusions are internal defects such as bubbles, cracks or other minerals, in the center of the diamond.
GIAdeveloped a universal diamond clarity grading scale consists of 11 notes. Diamond are graded under 10x magnification, so most of the defects in the clarity of the eyes are barely visible to the naked eye. In addition to the number, size and severity of inclusions, the position and color of the recording are also included, if the definition of purity of a diamond. Since no two diamonds equal, the characteristics of a diamond, and isInclusions, making it unique and, at times, like fingerprints to identify individual diamonds.
Most species are rare or clarity F FL (flawless) and IF (internally flawless) diamond of this type are much more valuable because it does not occur so often in nature. The following degrees are better clarity VVS (very, very small inclusions) and VS (very slightly included). These diamonds are more common and popular because it is more convenientlike a perfect diamond, but they have very small inclusions, many of which can be only one expert grader under magnification to see through. Probably the most common purity SI (slightly included). Diamond clarity this as "eye-clean" and offer an economical alternative. The lower purity (imperfect), gave me the most obvious inclusions that affect the brilliance of diamonds.
GIA clarity grading scale as defined by theirfollows:
* Flawless (FL)
No inclusions or blemishes are visible to the qualified recruiters with 10 times magnification
* Internally Flawless (IF)
N. inclusions and only minor flaws are visible to the qualified students at a magnification of 10 times
* Very, very slightly included (VVS1 and VVS2)
Inclusions are found qualified for a breeder difficult to see under 10x magnification
* Very Slightly Included (VS1 and VS2)
Inclusions are clearly visible under 10x magnification, butcan be described as low
* Slightly Included (SI1 and SI2)
The inclusions are obvious to the students trained at a magnification of 10 times
* Imperfect (I1, I2 and I3)
The inclusions are obvious under 10X magnification and may affect transparency and brilliance
Carats
The weight of a diamond is measured in carats, with one carat equals 200 milligrams or 1 / 5 grams, you can also hear the term "points" used when a diamond's weight. ACarat is divided into 100 points, so that a quarter of a carat diamond point diamond would be called '25. '
As the carat weight can also be used to measure precious stones, is more complicated, as a species have different densities gem. For this reason, a 6 mm round alexandrite, a carat weight of 1.30ct 0.70ct may be only a 6 mm round citrine.
If it is written is usually "ct". Abbreviated as Karat diamond jewelry piece in a different the abbreviation is used "ct total carat weight of meaning 'weight TW (the sum of the weights for each one carat diamond), although the limited mostly" the value of a similar item of equal carat CTW. "The value of such a piece of jewelry can be less than a diamond. Solitaire diamond weight are much rarer, and therefore a 1ct diamond solitaire ring is worth much more than a ring 1ctw comparable with many smaller> Diamond.
Even the same size and carat weight can not contain the same value of the diamond, because of color or clarity may be better. The cut of a diamond, but also about the carat weight and value, as some other diamond cuts have put more volume.
The four C described as the most important characteristics that the value of a diamond. But equally important is that the only rank and beauty of the diamondThe system of standardized assessment used to rank the quality of each diamond. We recommend the consumer to educate themselves about the grading diamonds and other jewelry related info.
