Diamond jewelry – Understanding the Four C’s

Diamond are one of the world’s most valued natural resources, not to mention one of the most highly desired gemstones. Diamond are naturally made by having an enormous variety of characteristics, making each individual diamond unique. For more information about Anonym Tafelgeschäft Kassel review our web-site.
The many possible mixtures of these characteristics determine the overall quality and value of a diamond. Realizing the need for an universal grading program, GIA, the Gemological Institute associated with America, regarded as the world’s respected institute of gemological research, created the Four C’s. The Four C’s stand for Cut, Color, Clearness, and Carat Weight. This internationally accepted diamond grading system has revolutionized the diamond trade now is used by nearly every professional in the industry and diamond enthusiasts across the globe. Mainly because individual diamond vary so greatly in quality and price, it is vital for consumers to be familiar with the 4 C’s as well. We’ve outlined the fundamentals of this grading system below, to help give consumers the resources they need to make educated purchases.

Cut

The cut of a diamond may be one of the most important of the Four C’s, and may enhance the overall quality, value, plus beauty of that diamond. There are many different cuts, each having a specific effect on these three attributes:

* Brightness – the amount of light the diamond demonstrates

* Fire – the various colours of the spectrum that a diamond emits

* Scintillation – the luster and brilliance that is produced if a diamond is moved

In a properly cut diamond, the light which enters through the table (the top flat facet) and travels through to the pavilion is then reflected plus dispersed through the crown, creating a desirable effect. Unfortunately, in a poorly cut diamond, some of the light leaks out the girdle, which dramatically reduces the diamond’s sparkle.

The quality of a diamond cut is based primarily upon symmetry and polish, as well as the ratios of the table size, crown position, and pavilion depth to one another. Generally, the more facets a diamond offers, the more brilliance and sparkle it will have. However the depth of the pavilion also has a huge impact on this. When the depth of the pavilion is either too much delete word enough, the light can be lost out the sides of the stone rather than being directed through the crown.

The particular brilliant round cut diamond is definitely the most common of the diamond cuts, although many others are gaining popularity. The brilliant round cut was designed specifically for use upon diamond, and with it’s 57-58 well proportioned facets, it’s brilliance and sparkle is more noticeable than on most cuts. Yet with so many variations of diamond cuts, many combinations associated with proportions are possible, directly impacting the beauty of a diamond, and therefore furthermore the value.

Color

Similar to the cut of a diamond, it’s color will possibly increase or decrease it’s twinkle and fire. Obviously, diamond along with less color will reflect more light than those with a light yellow or brown hue. This, combined with the fact that nature provides us along with less of these colorless diamond, makes it more valuable and sought after.

Once again seeing the need for an universal system, the GIA developed the gemstone color grading scale, using the words D-Z, which is most widely approved today. Diamond are graded below very precise viewing conditions and often compared to diamond of a known colour grade to ensure very few differences within a color grade. A diamond lacking of color is grade ‘D’ and the more color that is contained in the diamond, the further across the alphabet it’s grade travels. Gemstone with grade ‘Z’ will have a mild yellow or brown tint, and thus will not reflect light as well as a colorless diamond. Fancy colored diamond, although most are irradiated and color enhanced, do not follow this grading scale, and often are more valuable because when naturally colored they are extremely rare.
