Diamond Grading in 4C’s
Every diamond is distinctive and is a wonder of particular place and time, while each diamond has specific qualities that establish its significance. Diamond quality is the primary factor to be considered while choosing or rejecting it. There are four major factors that effects the quality of a diamond grading - Cut, Color, Clarity and Carat. These are also called as 4C’s of a diamond grading. Let’s have a glance how 4C’s impact the diamonds quality.
Diamond cut defines the polish, facets, reflective quantities and symmetry not defined with a shape. The overall beauty of a diamond hangs more on the cut than any other factor. Diamonds with excellent cutting grade emits the entire incoming light entered.
When a diamond is shaped from a rough stone, the faceted stone must balance the appearance along with yield, this is the reason grade of a cut is so necessary. In a perfect cut diamond the incoming light is reflected through all facets and attracts wearers, in case with poor cut grade only 20% emits and remaining 80% will go through the tip and it can’t be noticed by the wearers. Diamond cut mentioned with angles and proportions polished by the cutters that harness the diamonds internal brilliance and emit its best sparkle.
Proportions of a Diamond
Cut of a diamond influenced by reflection and physical features. A proportion of a diamond refers to the relationship between the size, shape, and angle of each facet of a diamond.
A well proportioned diamond will have each proper facet and well angled so as to reflect the maximum amount of incoming light. This Reflected light is perceived into three types; these factors highly affect the appearance of a diamond.
Brilliance - Brilliance or Brightness of a diamond is due to inner and outer reflection. Entered light from the top breaks into spectrum of colors and reflects inside and exist from the top along with a white light.
Fire - Fire is a scattering of white light into color spectrum. When light flashes on the diamond, the incoming light breaks into spectrum of colors and after inside reflection, it comes out separately into color flashes along with white light.
Scintillation - Scintillation is the white and colored sparks viewed when it is motion. Diamond is appraises with reflection and refraction properties.
To get a successful reflection physical features are very important. The basic features of a diamond that plays a vital role in diamonds cut are as follows:
Table – It is a largest plane surface of the diamond visible from the top view.
Crown – It is a top part from girdle to the table.
Girdle – It is a narrow band around widest part of the diamond. It separates top and bottom part of the diamond. It is also called as setting part.
Pavilion – It is a bottom part form girdle to cullet.
Culet – It is sharp point at the bottom of the diamond, just below the pavilion. It is usually not visible to naked eye.
Depth – The height from the culet to the table.
Color of a diamond is an important character to consider before buying a diamond. Every diamond body has a natural color. A pure diamond is always colorless and it looks like a clean water drop. The diamonds color evaluation is based on the absence of color. Diamond color doesn’t depend on the reflection of color spectrum. Actually diamonds are of so many colors. The basic color of a diamond ranges from colorless to little yellow and brown. Most diamonds have natural colors like yellow, brown in a very slight variation.
Diamond colors that are visible to naked eye are less in demand, poor quality, low cost; while the colorless diamonds are high in demand and also with good quality and costly. Even a slight variation in diamond color may changes its value. Now-a-days widely using grading system is D-Z color grading scale by GIA’s. In this color grading scale D is colorless and up to Z increase in color. Diamond color don’t change eventually, in case of colorless diamond, they let more light to pass than the colored diamond and releases more fire and radiance.
The color grade of a diamond as follows:
Colorless - D E F
D, E, and F color graded diamonds are high in quality can be detected only by a gemologist and rarely by the naked eye. It is a color less diamond looks icy white or water drop. These are extremely rarest, expensive and high in quality.
Near Colorless - G H I J
G-J graded diamonds are common than the D-F, they have a great value. In this I-J graded diamonds are available with half the price of a D diamond but with good in value and quality.
Faint Color - K L M
K-M graded diamonds have yellow tint and can easily visible to untrained eye. Users will observe and feel too much color with these graded diamonds. These are half the price of a G diamond.
Very Light Color - N-R
N-R color graded diamonds can easily seen yellow and brown tints on them. These are not expensive.
Light Color - S-Z
S-Z color graded diamonds have too much color for white diamonds. These are not original ones.
Natural diamonds are available deep inside the earth’s crust and exposed to tremendous pressure and heat. Due to this they may have some birth marks. These birthmarks are called inclusions (presents inside the diamond) and blemishes (presents outside the diamond). While the diamond clarity is a degree to which a diamond presents blemishes and inclusions. In general diamond clarity comes with purity and rarity. Diamonds with no or little inclusions and blemishes are considered particularly rarest and highly valued. Diamonds with more imperfections are low in value. These internal and external features are only visible to experienced craftsmen under 10x magnification. Diamond Clarity is also important factor to be considered while choosing a diamond. The GIA clarity scale grades diamond clarity from Included to Flawless.
The clarity grading of a diamond ranges from FL (Flawless) to I3 (Included).
|FL (Flawless)||No visibility of internal inclusions and external blemishes – Exceptionally rare, high quality, highly expensive|
|IF (Internally Flawless)||No visibility of internal inclusions - Exceptionally rare, high quality, expensive|
|VVSI 1&2 (Very Very Slightly Included)||So slight inclusions, but difficult for a skilled craftsmen to see under 10x magnification – Very high in quality, costly|
|VSI 1&2 (Very Slightly Included)||Inclusions are observed only for the skilled craftsmen under 10x magnification – Very good in quality, costly.|
|SI 1&2 (Slightly Included)||Inclusions are visible under 10x magnification, may have chances to naked eye also – Good in quality, cost is less than VSI diamonds.|
The last range is I 1,2 & 3 (Included), these are easily visible under 10x magnification and also untrained eye and these are very bad in quality and brilliance. So many inclusions are not visible to the trained or untrained eye due to their tiny size. Diamonds with VSI1 and SI2 grade may look exactly same, but they have lot of differences in quality. So this is reason expert evaluation is important for diamonds. It will help users to know the exact quality, brilliance and price of a diamond.
Carat is the unit of weight for a diamond. Diamond carat weight is the measurement used to measure the weight of the diamonds and color gemstones. In simple words, carat of a diamond refers to weight of a stone not its size. However both size and carat weight sounds confusing, but they have lot of difference. Size of a diamond indicates the diameter of it and carat is the overall weight of the diamond. One carat is equals to 200 milligrams or 0.2 grams. Diamond price varies the carat weight. Carat weight changes with the change in shape and cut of a diamond. Diamonds with equal carat weight don’t have the same size due to the difference in measurements.
Two diamonds with same carat weight can have different prices due to color, clarity and cut of it. Price of a diamond increases with carat weight. In general fact that twice the weight of a diamond costs around four times more. In carat weight of a diamond there is a cutoff weight. Usually under size diamonds carry cutoff weight. There are some standard cutoff weights – 0.25 ct., 0.50 ct., 0.75 ct., 0.90 ct., 1.00 ct., 1.50 ct., and 2.00 ct. In the process of maintaining the cutoff weight the beauty of a stone disappears.
