The criteria for a 4c diamond are CARAT, CLARITY, COLOUR and CUT. Carat refers to the unit of mass of gemstones, 1 carat is equal to 0.2 grams or 200 milligrams, one carat is divided into 100 points, to be used as a calculation of smaller stones; Clarity refers to the inclusions in a diamond. The number, size, shape and color of inclusions determine the clarity and uniqueness of a diamond. The cutting of diamonds is about symmetry and balance.
First, the 4c standard of diamonds
The 4c standard of diamond identification is the international standard that usually uses weight (carat), color, clarity (transparency), and cutting standards to measure the quality of diamonds. The 4c is the first letter of CARAT, COLOR, CLARITY and CUT. The parameters of the diamond 4c standard are different, and the price of the diamond is different, and the diamond 4c standard will affect the value and price of the diamond. The color of diamonds is divided into white diamonds and colored diamonds, for white diamonds, the closer the color of the diamond to pure white, its quality is very excellent.

Two, the four aspects of the 4c criteria for determining diamonds
The 4c standard for diamonds is determined from the following four aspects.
1, CARAT
Carat (Ct) is a unit of mass (weight) of a gemstone; 1 carat is equal to 0.2 grams or 200 milligrams. One carat is also divided into 100 points, such as 30 points, or 0.3 carats, to be used for smaller stones. Because the density of gemstones is basically the same, the heavier the gemstone, the larger the volume.
Weight is an important factor in determining the price of a diamond, and a 2 carat diamond of %% quality is often more expensive than two 1 carat diamonds of the same quality.
2. CLARITY
Clarity, as the name suggests, refers to the inclusions within a diamond. They are like natural birthmarks, and the number, size, shape and color of these inclusions determine the clarity and uniqueness of a diamond.
The clarity of diamonds is rated according to the number, size, and location of inclusions, and the GIA distribution Clarity table classifies diamonds from FL(internal flawless = no visible inclusions under 10x magnification) to I3(no, diamonds with visible inclusions).
3. COLOUR, colour, colour
The color of diamonds can be white or colored. For white diamonds, the closer the color of the diamond is to pure white, its quality is very excellent.
Diamond color evaluation and classification is based on GIA criteria, from D(premium white) to Z(light yellow or brown) alphabetically, a total of 23 equal %%.
4. CUT the cutter
The cutting of diamonds is about symmetry and balance. The cutting standard depends on the level of the diamond cutter. Cutting is the guarantee of a diamond's intoxicating beauty.
Darry Ring bright cut round diamonds weighing more than 0.30 carats are classified as "excellent" or "excellent" according to GIA's equal %% classification, thus guaranteeing the diamond's shine and exceptional brightness.
