Diamond symmetry

Refers to how precisely and accurately the diamond's facets and angles are cut and how they align with each other. It is one of the four Cs (carat weight, cut, clarity, and color) that determine the value and quality of a diamond.

The symmetry of a diamond plays a significant role in its overall appearance, as it affects how light interacts with the diamond and how it reflects and refracts off its surface. A diamond with excellent symmetry will have a balanced and uniform appearance, while one with poor symmetry may have uneven or misaligned facets, leading to a less attractive and less valuable diamond.

How Diamond Symmetry is Evaluated:

Diamond symmetry is evaluated on a scale of poor, fair, good, very good, and excellent. A diamond with excellent symmetry will have perfectly aligned and balanced facets, with no visible flaws or imperfections. The diamond's facets will be uniform in size and shape, with straight, smooth edges that meet at precise angles.

In contrast, a diamond with poor symmetry may have misaligned or uneven facets, with visible flaws or imperfections that affect its overall appearance and brilliance.

Diamond symmetry is typically evaluated using a 10x magnification loupe or microscope, which allows a jeweler or gemologist to examine the diamond's facets and angles in detail.

Factors That Affect Diamond Symmetry:

There are several factors that can affect the symmetry of a diamond, including:

  1. Cutting and Polishing Techniques: The quality of a diamond's symmetry is largely determined by the skill and expertise of the diamond cutter and polisher. Diamonds that are cut and polished by experienced professionals using high-quality equipment and techniques are more likely to have excellent symmetry.

  2. Diamond Shape and Cut: The shape and cut of a diamond can also affect its symmetry. Certain diamond shapes, such as round brilliant cuts, are easier to cut and polish symmetrically than others, such as pear or marquise cuts, which have more complex and asymmetrical shapes.

  3. Inclusions and Blemishes: Diamonds with visible inclusions or blemishes can also affect their symmetry, as the diamond cutter may need to make adjustments to the diamond's facets to avoid or minimize these imperfections.

  4. Clarity Grading: The clarity grade of a diamond can also impact its symmetry. Diamonds with a higher clarity grade are generally easier to cut and polish symmetrically, as they have fewer inclusions and blemishes that need to be worked around.

What is the symmetry of a diamond?

How nicely a diamond's facets are aligned is referred to as its symmetry. A diamond's symmetrical shape is crucial because, without a specific shape, it will not appear appealing. The quality of the light will increase with the number of diamonds used to reflect it or the amount of light shining on the diamond's polish. The layout, design, and covering of a diamond's face are all examples of symmetry. It is actually a cut variation of the diamond, and it may have an impact on how the diamond appears to the eye.

How does symmetry affect diamonds?

The diamond is impacted by symmetry; if the diamond is not symmetrical, the light will not reflect from it effectively, resulting in a change in the diamond's quality. The diamond's symmetry has an impact on how well it interacts with light and how bright it is. Good symmetry in a diamond allows light to travel through the diamond. When a diamond has perfect symmetry, light shining through it strikes the table; nevertheless, if the diamond has poor symmetry, the light will emerge from the corner or from below. The diamond appears lifeless when the light does not return to the eye.

Reflection required from the diamond:- 

Diamonds should be homogeneous when the shape is good, it will look a little but if the shape is disturbed, the diamond will not look good. When we look at an object, first light falls on it, then that light collides with it and comes to our eyes, then we are able to see the object. In this way, when we look at the shining object, then its shining depends on its texture its texture will be symmetric. So the light that enters the signal is reflected, and it will reflect in the eyes so that the object will see more shine.

Why we chose a symmetrical diamond?

When we buy any diamond jewelry, we buy it only after looking at its symmetry. diamonds jewelry like engagement rings and necklaces, hand bands. The value of a diamond depends on 4cs, but fluorescence, evenness, and polish have a significant impact on a diamond's value and overall countenance, and the cut grade of the stone. Diamond symmetry refers to the arrangement, contours, symmetry of the facets, and accuracy of the shape. According to GIA, symmetry grading considers 10 different features during valuation. Our company Shiv Shambhu provides the best quality diamond, the best symmetry of diamond, and the best texture. You will find the best quality and best texture diamonds in Shiv Shambu company. we will never let you break your faith. It is advisable to take a diamond which is an excellent and very good diamond to buy.


The symmetry of a diamond is an important factor in determining its overall beauty and value. A diamond with excellent symmetry will have perfectly aligned and balanced facets, with no visible flaws or imperfections. When purchasing a diamond, it's important to consider the symmetry, as well as the other three Cs (carat weight, cut, and clarity), to ensure that you are getting a high-quality and valuable gemstone.
