There are mostly two different kinds of grading system available in the world. One has been introduced by the Gemological Institute of America or GIA and the other one was developed by American Gem Society or AGS. These are the two most widely grading system with diamond retailers and users. The AGS system of grading of diamond was followed by the AGS affiliated retails primarily in the United States. But, to have the most common practice of diamond grading the businessmen are using the GIA system. The 4Cs, e.g., clarity, color, cut and carat weight will be disclosed here to identify the quality and identify a perfect diamond.
We often think that the diamond’s cut is associated with its shape, such as princes cut, or round cut, but the perfect diamond’s cut is associated with its grade of reflecting the light. You will be surprised that the perfectly or accurately cut diamond will interact nicely with the light. This is the thing which is the most crucial and significant thing to analyze and also an important factor. The people who are attached to the diamond trade know the importance of diamond’s cut, but for the ordinary or common people here is the factor which implies the elegance of a diamond’s cut.
In the diamond business, the diamond cut is also termed as – Proportions. It is mandatory to know the factors related with this “Proportions”. There are-
- Crown Angle
- Table diameter
- Angle Total depth percentage
- Pavilion depth
- Ratio of total depth with length
Previously the gradation was termed as Excellent, Very Good and Good. But as time passes, technology enhanced the gradation system was classified with 5 grades from Excellent to Poor. It has to be considered the polishes of each surface of the diamond, the weight against its diameter, the symmetrical values of each facet, and the restraint thickness. To know more click here.
Diamond clarity is the review of petite deficiencies on the face and inside. The facade defects are describing blemishes, and interior imperfections are identified as inclusions. These minute, usual blemishes and inclusions are infinitesimal and do not influence a diamond’s attractiveness in any way. Diamonds with the smallest amount and least inclusions are given the maximum clarity scores.
Clarity is one of the components of 4Cs of diamond rating and excellence. Diamond clarity is the slightest significant factor when selecting to buy a diamond since the majority of diamonds have blemishes and tiny inclusions that are minuscule, not capable to be seen with an untaught or autonomously.
Diamond carat weight is an estimation of how much a diamond gauges. A metric “carat” is characterized as 200 milligrams.
Every carat can be subdivided into a meter of 100 points scale. A jeweler may depict the heaviness of a Diamond lesser than one carat by its ‘points’ alone. For example, the jeweler may allude to a Diamond that gauges 0.25 carats as a ’25 pointer.’ Diamond weights more prominent than one carat are communicated in carats and decimals.
The diamond shade assessment of mainly gem-quality diamonds is rooted in the lack of color. A chemically clean and structurally ideal diamond has no shade, like a drop of clean water, and as a result, an elevated price.
