GIA 4C CERTIFICATION

Diamonds are one of the hardest materials known. It is a precious stone and is rare. It gains this precious feature from its adventure over millions of years under the ground. As with every product, diamonds are ranked in terms of quality within themselves. There are 4 main criteria that determine this quality and value. These are known as the 4C scales. Carat, Color, Clarity and Cut can be listed as factors that determine the value of a diamond.

GIA 4C Carat Weight Scale

Diamonds and other stones are weighed in metric carats. Carat is a unit of diamond weight (don't confuse karat here with "18K gold", which refers to the purity of gold). 1 carat is equal to 0.2 grams.

GIA 4C Color Scale

One of the most important features that affects the value of diamonds and distinguishes them from other diamonds is the color of that diamond. Colors range from colorless to slightly yellow or brown. It can be said that the closer a diamond is to colorless in this changing color scale, the more unique it is. As Kharis Jewellery, the majority of the diamonds in our products in our store consist of diamonds in the colorless category.

GIA's color grading scale starts with the letter D representing colorless and continues with increasing color presence up to the letter Z. Each letter grade that appears in the table has a clearly defined range of color appearance. In order to determine this color range, diamonds are color graded by comparing them to stones of known color under controlled lighting and sensitive viewing conditions. Many of these color separations are too subtle to be seen by a non-professional eye. However, these small differences create serious differences in diamond quality and price. One of the reasons for the price difference between two diamonds in the same carat on our site is the difference in diamond colors.

GIA 4C Clarity Scale

Diamonds formed under extreme pressure and heat deep in the soil can often contain some internal and external imperfections. The degree of clarity of the diamond is determined by the presence of these internal and external defects. Using the GIA International Diamond Grading System™, diamonds are assigned a degree of clarity ranging from flawless (FL) to obvious inclusions (I3). Inclusions are imperfections on the inside of a diamond that affect clarity.

Every diamond is unique. Spots appear on many diamonds under 10x magnification. However, near-perfect diamonds almost do not contain these blemishes. Most jewelers have not even seen these extremely rare diamonds. The very high prices of such diamonds are because they are really hard to find.

The GIA Clarity Scale includes 11 grades and most diamonds fall into the VS or SI categories. When determining this degree of sharpness, it takes into account the size, structure, position, color or relief, and amount of sharpness features visible under a 10x microscope.

GIA 4C Cut

Cut quality is an important factor in how a diamond emits light, nurturing its sparkle and brilliance. The charm and beauty of a particular diamond is more dependent on the cut quality than anything else. The only point where human beings interfere with the diamond can be called the cutting part. The diamond should be cut in such a way that its brilliance is dazzling, and wherever the light comes from, it is the diamond that first catches the eye.

The GIA Diamond Cut Rating System for standard round diamonds in the D to Z color range is based on the evaluation of seven components. The first three; brilliance (the total light reflected from a diamond), how it radiates light (the scattering of light into the colors of the spectrum), and luminosity (the pattern of light and dark areas and how light shines or shines as the diamond is moved) — aspects based on appearance. The remaining four -- weight ratio, durability, polish and symmetry -- relate to the design and craftsmanship of a diamond.
