How To Grade Precious Gems

An amateur needs to conduct appropriate research before actually going to a retail store outlet to obtain a diamond ring or diamond jewelry. In essence, diamond grading evidently seems to be an extremely complicated process because of the various approaches that are employed. However, in reality, there are 4 major characteristics that are considered while valuing diamond 
jewelry. The 4 main attributes are the following; cut, clarity, carat weight and color. On the other hand, these four features are commonly referred to as the 4 Cs of diamond grading and this write-up will predominantly make an effort to explain them to you in as easy terms as possible.

Gemstone Cut

The degree of reflectiveness or brilliance that a diamond offers can be gauged by the quality of its cut. But you cannot mix up this feature with the over-all profile of the diamond under consideration. Cut in particular takes on an incredibly vital role during the process of assessment of a particular diamond but has also been deemed as being an extremely difficult certifying aspect to understand 
because it is more subjective in nature. The cut of a particular diamond can be labeled as ideal, premium, very good, good, fair and poor in accordance with its comparative quality. Therefore, a brilliant stone will probably be labeled as ideal whereas a dull looking diamond will be called poor.

Gemstone Lucidity

On the other hand, diamond clarity is referred to as the amount of visible flaws upon the surface as well as the internal area of a particular diamond. Consequently, it is [easier to grade by clarity in comparison with cut. These defects are commonly known as blemishes. With regards to labelling, an ’F’ or flawless label is used for a diamond that has no visible flaws. ‘IF’ or internally flawless lable denotes a diamond that does not possess any internal blemishes except ones on its outside. VVSI (Very Very Slighyly Included), VS (Very Slightly), SI (Slightly Included) as well as I (Included) are alternative terms which are used to distinguish between diamonds of varying quality. Consequently, as a general rule, experts will grade a flawless diamond as being incredibly valuable while a diamond with a label ‘I’ will probably be deemed as being a much cheaper option in value.

Gemstone Coloration

Diamond color is essentially defined as the amount of coloration that exists within a particular diamond’s interior. Generally, the less coloration that may be visible indicates a high quality diamond. In accordance with color grading, authorities have denoted a selection 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 completely colorless.

Diamond Carat Weight

Carat weight has a considerable impact upon the price of a diamond since a jewel with a large carat weight will be more expensive than the one which has a smaller carat weight. So even though other grading features rate a diamond to be more costly than an other one, the diamond having the greater carat weight will always be more expensive. Thus, always try to achieve an equilibrium between grading attributes which fundamentally 
implies that you ought to go for a diamond which rates higher in terms of features such as clarity and cut but carries a smaller carat weight such as 1 or even less than that.

Diamond certification organisations have been formed so as to maintain fairness while grading diamonds. Vendors don’t have the expertise to grade diamonds which is why just about every reputable diamond store such as James Allen and Blue Nile will grade its diamond inventory through independent organizations such as the Gemological Institute of America (GIA).
