How to distinguish the grades of diamonds

Diamond is a very expensive jewelry. Because diamonds are very shiny, many people like to buy jewelry with diamonds. For example, when buying a wedding ring, you would prefer to buy a diamond ring. Since people love diamonds so much and want to buy them, it is necessary to understand how to differentiate the grades of diamonds. After all, diamonds are divided into many different grades.

The color grading system does not apply to fancy color diamonds.

Grade D: Completely colorless. Highest color grade, extremely rare!

Grade E: Colorless. Only gemologists can detect trace amounts of color. A very rare diamond

Grade F: Colorless. Small amounts of color can only be detected by jewelry experts, but it is still considered colorless. It is a high quality diamond.

GH grade : nearly colorless. Slightly tinted when compared to higher color grade diamonds. But diamonds of this color grade are still very valuable.

IJ grade: nearly colorless. Slight color is detectable. Higher value.

KM grade: darker color, poor fire, not available on Davidini Jewelry Network, and customers are advised not to use it.

NZ grade: darker in color, poor in fire, not available on Davidini Jewelry Network, and customers are advised not to use it.

2Diamond Carat Grading Table

Diamond Weight (Carat) Grade Table: Diamond weight is calculated in carats (CT). 1 carat = 0.2 grams = 100 points. 0.75 carats is also known as 75 points. When other conditions are similar, as the weight of the diamond increases, its value increases exponentially; diamonds of the same weight can have very different values ​​due to differences in color, clarity, and cut. Diamonds with a carat weight of more than 50 points have the ability to maintain and increase their value. The larger the carat, the more breathtaking their charm.

3Diamond Clarity Grade Table

Every diamond contains natural inclusions, like natural birthmarks. The number, size, shape and color of these inclusions determine the clarity and uniqueness of a diamond. Inclusions are hidden inside the diamond and can appear in different colors: white, black, colorless, or even green or red. Most inclusions cannot be discerned with the naked eye and can only be clearly seen under a 10x magnifying glass. Clarity is a grading system that measures the amount of inclusions and blemishes: from FL/IF (Flawless/Internally Flawless) to I (Imperfect). Grade I clarity means inclusions can be seen with the naked eye. 4

Diamond Cut Grade Table

EXCELLENT: represents a standard that only 3% of top-quality diamonds can achieve. This cut causes the diamond to reflect nearly all the light that enters it. It is an elegant and outstanding cut.

Very good cut: represents about 15% of diamond cuts. It can make the diamond reflect the same light as a standard grade cut, but the price is slightly lower.

Good cut (GOOD): represents about 25% of diamond cuts. Diamonds reflect most of the light that enters them. Much cheaper than VG grade.

Fair Cut (FAIR): represents a diamond cut with a roughness of 35%, which is still a high-quality diamond, but the light reflected by a fair cut diamond is not as good as that of a G cut.

Poor Cut (POOR): This includes all diamonds that do not meet general cut standards. These diamonds are cut either deep and narrow or shallow and wide, which tends to allow light to escape from the sides or bottom, making the diamond lose its brilliance. DAVINI does not offer diamonds of this inferior cut.
