DIAMOND
..formed in nature, has a hardness of 10 on the Mohs scale. Renowned for being the hardest substance on earth. The most precious and enduring of all gemstones, with their very name taken from the ancient Greek word adámas (αδαμας) meaning `unbreakable`. For centuries their exquisite beauty, durability, rarity, allure, sparkling inner fire and unique physical qualities have made them prized above all other gems. The most famed and fabled of all gemstones, very unique in many ways.
The Anatomy of a Diamond
The 4Cs
Every diamond, like a human fingerprint, has certain distinguishing characteristics. The 4Cs—color, clarity, cut and carat weight—are the globally accepted standards for assessing the quality of a diamond.
1. Cut
Why Is Diamond Cut Important?
Put simply, cut is responsible for the quality of a diamond’s sparkle. If a diamond is cut poorly, it will appear dull even if it has a high color and clarity grade. If a diamond is cut well, it will reflect and refract light for maximum brightness and sparkle.
What Is Triple Excellent Cut?
A triple excellent cut is the highest grade for round brilliant diamonds across the industry. To receive this superior grade, a diamond must meet “excellent” standard across three factors: precision of cut, polish and symmetry. Ultimately, a triple excellent diamond maximizes light return, or brilliance, resulting in a stone that sparkles beyond compare.
What Is Diamond Cut?
The most important of the 4Cs, Cut refers to how a diamond’s facets interact with light. It is determined by symmetry, proportion and polish. More than any other factor, cut determines the beauty of the stone. TeutaGold diamonds, from the smallest to the largest stone, are always cut to prioritize brilliance over carat weight.
Cut is the only one of the 4Cs that is affected by human hands. Two diamonds may have the same clarity, color and carat weight, but cut is what determines whether or not one is superior to the other.

What diamond cut sparkles the most?
The round brilliant diamond, which has 57 to 58 facets, is the most brilliant of the diamond cuts.
What is the difference between a diamond cut and a diamond shape?
It’s important to note that diamond cut and diamond shape are not the same thing. A diamond’s cut determines how its facets interact with light. A shape describes the geometric appearance of a diamond.
2. Clarity
What Is Diamond Clarity?
Diamond clarity is a measure of the purity and rarity of the stone, graded by the visibility of these characteristics under 10-power magnification. A stone is graded as flawless if, under 10-power magnification, no inclusions (internal flaws) and no blemishes (external imperfections) are visible.
Since diamonds form under tremendous heat and pressure, internal and external characteristics are common. These characteristics help gemologists separate natural diamonds from synthetics and simulants, and identify individual stones.

Does Diamond Clarity Really Matter?
A diamond with a poor clarity grade has multiple inclusions,
which directly affects sparkle. Because inclusions hinder the
refraction and return of light, the lower the clarity grade,
the cloudier the diamond will appear.

3. Color
What Is Diamond Color?
Color refers to the natural tint inherent in white diamonds. In nature, most white diamonds have a slight tint of yellow. The closer to being “colorless” a diamond is, the rarer it is. The industry standard for grading color is to evaluate each stone against a master set and assign a letter grade from “D” (colorless) to “Z” (light yellow).

The gemological standards in this section refer only to individually registered engagement diamonds set in certain ring styles.
Color grades are established by comparing each diamond to a set of master comparison diamonds. Each grade represents a range of color. Grading color is done in a specific and controlled lighting environment and according to strict color grading procedures.
4. Carat
What Is Diamond Carat?
Carat is the standard unit of weight for diamonds and other gemstones.
Carat denotes the weight of a diamond, not the size. Diamond is measured to 1/1000th of a carat; one carat equals .20 grams.
Diamond prices increase exponentially with carat weight. So, a 2-carat diamond of a given quality is always worth more than two 1-carat diamonds of the same quality.
Carat weight can appear differently across different diamond shapes such as round brilliant, princess, pear, oval, cushion, marquise, emerald, radiant or heart. A diamond may have a higher carat weight without appearing larger and two diamonds of the same carat weight can vary in size if one is cut deeper than the other. In other words, it is important to note that carat weight does not necessarily denote size.
