How To Rank Precious Gems
Sunday, April 17th, 2011An amateur really needs to carry out appropriate research before actually going to a retail store outlet to obtain a diamond ring or jewelry. In essence, gemstone grading evidently appears to be an incredibly complex process because of the numerous techniques that are utilized. The quality of diamond jewelry depends upon 4 main features. These include cut, color, in addition to clarity along with carat weight. On the other hand, these four features are commonly categorised as the 4 Cs of diamond grading and this article will predominantly attempt to explain them to you in as easy terms as possible.
Diamond Cut
The cut aspect connected with diamond grading indicates the refractory index or brilliance of a diamond. However, one has to take care by not confusing it with the shape of a diamond since cut and structure are two
inherently distinct features. Cut in particular plays an incredibly vital role during the process of evaluation of a particular diamond but has also been regarded as being an extremely challenging certifying aspect to comprehend
since it is more subjective in nature. The cut of a distinct diamond can be defined as ideal, premium, very good, good, fair and poor in accordance with its relative quality. Consequently, an extremely brilliant diamond will likely be termed as ideal though, on the other hand, a dull diamond will be called fair or poor.
Precious stone Lucidity
Clarity concerns the flaws which exist upon the surface or the interior portions of a particular diamond. For this reason experts as well as amateurs find it easier to deal with clarity as a defining factor rather than grade by clarity in comparison with cut. These defects are commonly referred to as blemishes. With regards to labelling, an ’F’ or flawless label is applied for a diamond that has no noticeable flaws. Likewise, ‘IF’ or internally flawless is used for a diamond
that only comprises of flaws upon its surface area. VVSI (Very Very Slighyly Included), VS (Very Slightly), SI (Slightly Included) along with I (Included) are alternative terms that are used to differentiate between diamonds of varying quality. Therefore, in most cases, experts will grade a flawless diamond as being extremely valuable while a diamond with a label ‘I’ will probably be deemed as being a much cheaper option in value.
Diamond Coloration
The color of a diamond pertains to the pigmentation, visible to the naked eye, that is present within its core. Generally, the less coloration that is visible denotes a high quality diamond. In accordance with color grading, authorities have denoted a range of grades (D to X) where X is utilized for diamonds with a lot of coloration while D is used for extremely valuable diamonds that are absolutely colorless.
Diamond Carat Weight
While comparing two diamonds, the high-priced jewel will be the one which has the larger carat weight. That is why, inspite of the other 4 Cs, a diamond having a larger carat weight rating will always be more expensive than others. Thus, always try to achieve an equilibrium between grading attributes which essentially
implies that you ought to go for a diamond which rates higher in terms of features including clarity and cut but carries a smaller carat weight such as 1 or even less than that.
Precious stoneCertificates
Essentially, to promulgate and improve the quality of certifying techniques, independent as well as globally recognized diamond certification societies have been built
in order to accurately determine standards with regards to diamond certifications which are followed across the world. Vendors cannot be permitted to have authority over grading techniques and this is exactly why top quality retail stores including James Allen along with Blue Nile more often than not certify their stock through these types of international organizations including the Gemological Institute of America (GIA).
