Unveiling The Secrets Of Diamond Grading: Discover The Nelson Neumann Grade
What is Nelson Neumann Grade?
Nelson Neumann Grade is a grading system used to assess the quality of diamonds. It was developed by Nelson and Neumann, two diamond experts, in the early 20th century. The system is based on a scale of 1 to 10, with 10 being the highest quality diamond. The grade is determined by a number of factors, including the diamond's clarity, color, cut, and carat weight.
Nelson Neumann Grade is one of the most widely used diamond grading systems in the world. It is used by jewelers, diamond dealers, and consumers to assess the quality of diamonds. The system is reliable and consistent, and it provides a good indication of the diamond's overall quality.
There are a few key differences between Nelson Neumann Grade and other diamond grading systems. First, Nelson Neumann Grade is more comprehensive than other systems. It takes into account a wider range of factors, including the diamond's clarity, color, cut, and carat weight. Second, Nelson Neumann Grade is more consistent than other systems. It is based on a set of objective criteria, and it is not subject to the same level of subjectivity as other systems.

Nelson Neumann Grade
The Nelson Neumann Grade is a diamond grading system that assesses the quality of diamonds based on a scale of 1 to 10, with 10 being the highest quality diamond. The system is based on a number of factors, including the diamond's clarity, color, cut, and carat weight.
The key aspects of the Nelson Neumann Grade are as follows:
- Clarity: The clarity of a diamond refers to the number and size of inclusions (imperfections) in the diamond. The fewer inclusions, the higher the clarity grade.
- Color: The color of a diamond refers to the amount of yellow or brown tint in the diamond. The less tint, the higher the color grade.
- Cut: The cut of a diamond refers to the way the diamond has been cut and polished. The better the cut, the more sparkle and brilliance the diamond will have.
- Carat weight: The carat weight of a diamond refers to the weight of the diamond in carats. The larger the carat weight, the heavier the diamond.

Clarity
Clarity is one of the four Cs of diamond grading, along with color, cut, and carat weight. It is an important factor to consider when purchasing a diamond, as it can affect the diamond's appearance, durability, and value.
The Nelson Neumann Grade takes into account the clarity of a diamond when determining its overall grade. Diamonds with fewer inclusions will receive a higher grade than diamonds with more inclusions. This is because inclusions can affect the diamond's transparency and brilliance.
For example, a diamond with a high clarity grade will be more transparent and will have more sparkle than a diamond with a low clarity grade. This is because the inclusions in a low-clarity diamond will scatter light, making the diamond appear less brilliant.
The clarity of a diamond is also important for its durability. Diamonds with more inclusions are more likely to chip or break than diamonds with fewer inclusions. This is because the inclusions can weaken the diamond's structure.
When purchasing a diamond, it is important to consider the clarity of the diamond in addition to the other Cs of diamond grading. By considering all of the Cs, you can choose a diamond that meets your needs and budget.
| Clarity Grade | Number of Inclusions | Appearance | Durability |
|---|---|---|---|
| FL | No inclusions | Very transparent and brilliant | Very durable |
| IF | Very few inclusions | Very transparent and brilliant | Very durable |
| VVS1 | Very, very small inclusions | Very transparent and brilliant | Very durable |
| VVS2 | Very, very small inclusions | Very transparent and brilliant | Very durable |
| VS1 | Very small inclusions | Transparent and brilliant | Durable |
| VS2 | Very small inclusions | Transparent and brilliant | Durable |
| SI1 | Small inclusions | Slightly included | Durable |
| SI2 | Small inclusions | Slightly included | Durable |
| I1 | Inclusions visible to the naked eye | Included | Less durable |
| I2 | Inclusions visible to the naked eye | Included | Less durable |
| I3 | Large inclusions visible to the naked eye | Included | Less durable |
Color
The color of a diamond is one of the four Cs of diamond grading, along with clarity, cut, and carat weight. It is an important factor to consider when purchasing a diamond, as it can affect the diamond's appearance, value, and durability.
The Nelson Neumann Grade takes into account the color of a diamond when determining its overall grade. Diamonds with less yellow or brown tint will receive a higher grade than diamonds with more tint. This is because the tint can affect the diamond's appearance and value.
For example, a diamond with a high color grade will be more colorless and will have more sparkle than a diamond with a low color grade. This is because the tint in a low-color-grade diamond will absorb light, making the diamond appear less brilliant.
The color of a diamond is also important for its value. Diamonds with less tint are more rare and valuable than diamonds with more tint. This is because colorless diamonds are more difficult to find and are in higher demand.
When purchasing a diamond, it is important to consider the color of the diamond in addition to the other Cs of diamond grading. By considering all of the Cs, you can choose a diamond that meets your needs and budget.
The following table provides a summary of the Nelson Neumann Grade color scale:
| Color Grade | Appearance | Value |
|---|---|---|
| D | Colorless | Most valuable |
| E | Near colorless | Very valuable |
| F | Faint yellow or brown tint | Valuable |
| G | Very faint yellow or brown tint | Less valuable than D-F |
| H | Slightly yellow or brown tint | Less valuable than G |
| I | Light yellow or brown tint | Less valuable than H |
| J | Yellow or brown tint | Least valuable |
Cut
The cut of a diamond is one of the four Cs of diamond grading, along with clarity, color, and carat weight. It is an important factor to consider when purchasing a diamond, as it can affect the diamond's appearance, value, and durability.
The Nelson Neumann Grade takes into account the cut of a diamond when determining its overall grade. Diamonds with a better cut will receive a higher grade than diamonds with a poor cut. This is because the cut of a diamond affects its ability to reflect light and create sparkle and brilliance.
- Brilliance is the amount of white light that is reflected from the diamond. A diamond with a good cut will have more brilliance than a diamond with a poor cut.
- Fire is the amount of colored light that is reflected from the diamond. A diamond with a good cut will have more fire than a diamond with a poor cut.
- Scintillation is the amount of sparkle that a diamond has. A diamond with a good cut will have more scintillation than a diamond with a poor cut.
The cut of a diamond is also important for its durability. Diamonds with a good cut are less likely to chip or break than diamonds with a poor cut. This is because the facets of a well-cut diamond are more evenly distributed, which makes the diamond more resistant to damage.
When purchasing a diamond, it is important to consider the cut of the diamond in addition to the other Cs of diamond grading. By considering all of the Cs, you can choose a diamond that meets your needs and budget.
Carat weight
Carat weight is one of the four Cs of diamond grading, along with clarity, color, and cut. It is an important factor to consider when purchasing a diamond, as it can affect the diamond's appearance, value, and durability.
The Nelson Neumann Grade takes into account the carat weight of a diamond when determining its overall grade. Diamonds with a larger carat weight will receive a higher grade than diamonds with a smaller carat weight. This is because carat weight is a measure of the diamond's size, and larger diamonds are more rare and valuable.
For example, a 1-carat diamond will be more valuable than a 0.5-carat diamond, even if the two diamonds have the same clarity, color, and cut. This is because the 1-carat diamond is larger and therefore more rare.
The carat weight of a diamond is also important for its durability. Larger diamonds are more likely to chip or break than smaller diamonds. This is because the larger surface area of a larger diamond makes it more susceptible to damage.
When purchasing a diamond, it is important to consider the carat weight of the diamond in addition to the other Cs of diamond grading. By considering all of the Cs, you can choose a diamond that meets your needs and budget.
The following table provides a summary of the relationship between carat weight and the Nelson Neumann Grade:
| Carat Weight | Nelson Neumann Grade |
|---|---|
| 0.5 carats or less | Grades 1-5 |
| 0.51-1.00 carats | Grades 6-8 |
| 1.01 carats or more | Grades 9-10 |
