4C's of Diamond

What are 4C's of Diamond Quality?

Lab-Grown diamonds receive grading reports from independent gemological organizations on the 4C’s: Cut, Color, Clarity, Carat Weight.

Clarity

Clarity

Clarity Scale includes eleven clarity grades ranging from Flawless to I3.Because diamonds form under tremendous heat and pressure, it is extremely rare to find a diamond that lacks any internal and external characteristics. These characteristics are a by-product of its formation and help gemologists separate natural diamonds from synthetics and simulant, and identify individual stones.
There are FL, IF, VVS1,VVS2, VS1, VS2, SI1, SI2, I1, I2, and I types of clarity.

Color

Color grades are determined by comparing each diamond to a master set. Each letter grade represents a range of color and is a measure of how noticeable a color is. Fluorescence Some diamonds can emit a visible light when exposed to ultraviolet radiation, but fluorescence is not a factor in determining color or clarity grades. However, a description of its strength and color is provided on Reports as an additional identifying characteristic.

Color Scale extends from D (colorless) to Z (light yellow or brown). Although many people think of gem quality diamonds as colorless, truly colorless diamonds are actually very rare. Most diamonds used in jewelry are nearly colorless with tints of yellow or brown.

Carat

Carat

One Carat equals 200 milligrams in weight. For diamonds under one carat, each carat is divided into 100 points – similar to pennies in a dollar. 0.75 ct. = 75 points, 1/2 ct. = 50 points.

The Carat weight of diamond, we can also say the size of the diamond.

Cut

Cut Scale ranges from Excellent to Poor. A polished diamond’s beauty lies in its complex relationship with light.
Cut means Not Shapes, Here CUT Means the Quality of Diamond Cut.Those are EXCELLENT, VERY GOOD, GOOD and POOR.

The magnificent display you see is made up of three attributes: Brightness is the combination of all white light reflecting from the surface and interior of a diamond. Fire describes the “flares” of color emitted from a diamond. Scintillation describes the pattern of light and dark areas and the sparkle you see when the diamond, the light, or the observer moves. A diamond’s proportions affect its light performance, which in turn affects its beauty and overall appeal. Diamonds with fine proportions, symmetry, and polish optimize their interaction with light, and have increased brightness, fire, and scintillation.
