Diamond Engagement Rings – Colour Grading A Diamond

Diamond engagement rings are the best friends of ladies. These rings represent and formalize agreements for future marriages. And for ladies, having their partners ask their hands in marriage is one of the happiest moments in their lives.
Customarily, it is the man who visits the jewelry store to shop around for the right engagement ring for his lady. Getting an engagement ring can be really difficult as there are lots of varieties, styles, and designs in the market. In addition, upon closer look of a diamond, one would see that it has a slight tint to it. That hue constitutes a part of the four C’s—clarity, carat weight, cut, and color—that determine the quality of a diamond. In this writing, we will talk about the last C, which is color.
Many diamonds are not truly colorless. The hue comes from impurities that are molecularly embedded in the carbon that makes up the diamond. Yet it is the pure colorless diamonds, often called white diamonds, which all other hues are judged to.
The Gemological Institute of America (GIA) has created a set of guidelines to find out the true color of a diamond. The tint of a candidate diamond is compared to the color of a few control stones, which are pre-selected to a specific colour.
The diamond that is to be graded must be a loose stone. This means it must not be set into the metal since the metal can alter the natural hue of the stone. Next, the candidate diamond is placed table-down, pavilion-up beside the control stone. It is then viewed and analyzed with a 10X loupe. A letter system from D to Z is then used to determine the the diamond’s color with D being given to rare, completely colorless diamonds.
* D to F – colorless or white
* G to J – almost colorless
* K to M – tinted in a barely imperceptible yellow hue
* N to R – lightly tinted in a yellow hue. The color can be seen by the human eye, even without special grading equipment
* S to Z – moderately tinted, progressing to brown. The hue is visible even when the diamond is installed on the band.
