Learn about the most important Diamond Grader skills, how you can utilize them in the workplace, and what to list on your resume.

Diamond graders are experts in the field of diamond grading and evaluation. They use their skills to assess the quality of diamonds and provide accurate reports to clients. If you’re interested in a career as a diamond grader, it’s important to understand the skills that are necessary for the job. By learning about the skills required for diamond grading, you can better prepare yourself for a career in this field.

Cutting Styles

A diamond grader must be able to identify the different types of cuts that diamonds can have. This includes knowing how to identify a round cut, princess cut or other common shapes and styles. The ability to recognize these styles is important because it allows you to properly assess the value of each stone based on its quality.

Attention to Detail

Attention to detail is a skill that can help diamond graders perform their job well. This skill involves noticing small details and making sure they’re correct. For example, if a diamond has an imperfection, a diamond grader with attention to detail would notice it and make sure the diamond received the proper grade based on its condition.

A person who performs this job may also need to keep track of records for each diamond they grade. Attention to detail can help them remember which diamonds have already been graded so they don’t repeat the process unnecessarily.

Fine Motor Skills

Fine motor skills are the small movements of your hands and fingers. They allow you to perform tasks like sorting diamonds by size, shape and color. To improve your fine motor skills, try using a microscope or magnifying glass for close work. You can also practice writing with a pen or pencil.


Concentration is the ability to focus on one task at a time. This skill can help diamond graders stay focused during their work, which ensures they make accurate decisions when grading diamonds. It’s important for diamond graders to be able to concentrate while working with small details and patterns in diamonds. They also need to maintain concentration throughout long shifts so they can accurately grade each diamond that comes through their station.


Certificates are proof that someone has completed a course of study. They can be issued by an employer or educational institution and may include information about the subject matter, level of achievement and date of completion. Certificates can help you advance in your career and show potential employers that you have the necessary skills to perform the job well.


Simulants are artificial diamonds that can be used to trick a machine into thinking they’re real. Graders need to know how to identify simulants so they can avoid purchasing them. They also use their knowledge of simulants to help customers understand the difference between natural and artificial diamonds.

Clarity Characteristics

Clarity is the ability to understand and interpret information. As a diamond grader, you need clarity when reading reports about diamonds so that you can identify their characteristics accurately. You also need clarity when communicating with other members of your team or clients so they know what you mean. This ensures that everyone understands each other and reduces confusion.


Fluorescence is the ability to identify inclusions, or flaws, within a diamond. A diamond grader who has fluorescence skills can more accurately grade diamonds and help customers find high-quality gems. Fluorescence involves using ultraviolet light to see imperfections on a diamond’s surface. This skill requires attention to detail and patience as it may take time to notice all of the inclusions on a diamond.


Synthetics refers to the ability to identify when a diamond is treated or enhanced. This can be important for ensuring that customers are receiving natural diamonds and not synthetic ones, which may have different properties. For example, some treatments can make diamonds appear whiter than they actually are, so it’s important to know if a diamond has been treated before purchasing it.

Colored Diamonds

Colored diamonds are those that have a distinct color, such as blue or green. Colored diamonds can be rare and valuable, so diamond graders need to know how to identify them correctly. This requires the ability to distinguish between colors and understand what each color means in terms of value. For example, a blue diamond is more valuable than a white one because it’s rarer.

4Cs of Diamonds

The 4Cs are the industry standard for describing diamond quality. The four categories include cut, clarity, carat and color. Graders use these standards to determine a diamond’s value. For example, if a diamond has exceptional clarity, it may be more valuable than one with an average clarity grade.


Patience is the ability to wait for something. As a diamond grader, you may need patience when waiting for customers to make their purchase decisions or when waiting for your manager to review your work. Being patient can help you maintain composure and remain calm in stressful situations. It’s also important to be patient with customers who are making large purchases because it can help build trust between you and them.

Diamond Shapes

Diamond graders use diamond shapes to identify the quality of a diamond. They can determine if a diamond is an oval, square or rectangular shape and how it affects its value. Diamond graders also use this skill when they examine diamonds for flaws. For example, some flaws may only appear in certain shapes, so knowing what each shape looks like helps them find these flaws more quickly.

Spatial Awareness

Spatial awareness is the ability to understand and interpret a physical space. Diamond graders use spatial awareness when examining diamonds, as they need to know where each aspect of the diamond is located in order to grade it accurately. Spatial awareness can also help diamond graders determine if a diamond has been tampered with or altered in any way.

Color Discrimination

Color discrimination is the ability to differentiate between colors. This skill can be useful in diamond grading because it allows you to identify flaws and determine a diamond’s value based on its color. For example, some diamonds have naturally occurring dark spots that make them less valuable than other diamonds of the same size and shape. By using your color discrimination skills, you can grade these diamonds accurately and sell the ones with lower values at a discounted price.


Treatments are the processes that diamond graders use to grade diamonds. Treatments can include a variety of methods, such as using microscopes or ultraviolet light to examine the diamond’s clarity and color. It’s important for diamond graders to have knowledge about different treatments so they can accurately grade each diamond.

How Can I Learn These Diamond Grader Skills?

There is no one-size-fits-all answer to this question, as the best way to learn the skills needed to become a diamond grader may vary depending on your prior experience and knowledge. However, some ways to learn these skills include studying the 4Cs of diamonds, taking courses on diamond grading and evaluation, and practicing with simulants or synthetic diamonds. It is also important to be patient and have a keen eye for detail, as well as good fine motor skills, when grading diamonds.
