What Is Diamond Symmetry

Diamond Symmetry Chart and Meaning to determines the appearance

Diamond symmetry is present in the faceting and polishing style of a particular diamond. In other words, diamond symmetry has a nickname, and it is known as "main part of the diamond." When you see the pavilion faceting styles or arrows, then it is called symmetry, and it is very important to the diamond's reflection sparkling lights. Customers and jewelers select excellent and very good-grade symmetry in engagement rings and wedding necklaces.

  • What is diamond symmetry?

Diamond symmetry guarantees that the diamond is able for purchased by the buyer. Diamond symmetry represents the pavilion facets and dimensions. When all pavilion facets are matched with each other, then the symmetry throws sparkles. Diamond Symmetry is the fact which decides the diamond's appearance.

Diamond symmetry has the ability to reflect light through the facets, but the proportions depend on it. When diamond symmetry has an excellent grade, then it clearly symbols that the diamond is ready to buy.Diamond symmetry report suggest and indicates the buyer to select best graded diamonds like as Excellent Symmetry, Very Good Symmetry, Good Symmetry

  • Difference between diamond cut grade and symmetry grade

The differential fact of diamond cut and symmetry grade is its making style. Diamond cut grade is decided by girdle size and faceting styles. While symmetry grade is based on the pavilion faceting pattern. In a comparison of diamond cut and symmetry, diamond symmetry is more important than cut because the cut is not essential.

Diamond cut grade is decided in the microscope machine by inspecting all components. While diamond symmetry grade is decided with fluorescence sparkles.

Thus, the difference between diamond symmetry grade and diamond cut grade is the pavilion facets and girdle surface width and length.

  • Why symmetry grade is very important in diamonds?

Diamond symmetry grad is important in the appearance because from that diamond's light reflection ability identified. Diamond symmetry presents the internal and external structure faceting patterns and level. From that a diamond symmetry grade is decided.

  • What are diamond symmetry grades?

Diamond Symmetry has five main types, which are known as follows:-

Symmetry Grades Speciality

1. Excellent symmetry grade

All pavilion facets are placed with exact proportions.
2. Very good symmetry grade Some pavilion facets are not placed with exact proportions.
3. Good symmetry grade Diamond pavilion facets are curved and mismatched with each other.
4. Fair symmetry grade In fair symmetry grade diamond pavilion facets are not matched
with each other as usual.
5. Poor symmetry grade All pavilion facets are not placed with their ideal proportions. That's why
 poor symmetry grade diamonds are ignored
by 99% of customers
.

As diamond experts, we recommend only excellent or very good symmetry ahead of the rest symmetry types. For the overall appearance of a diamond,  symmetry plays all innings for a brilliant or ugly look.

If you don't know about diamond symmetry, you should read its types. After reading the classes, you should decide whether a diamond is ready for purchase or not.

  • What is an excellent symmetry grade?

In this type of symmetry, a diamond reflects 4X brilliant light reflects due to pavilion facets matching each other. At the same time, triangle and 90-degree facets are also placed with the best and most elite craftsmanship.

Excellent symmetry grade represents that pavilion facets are gathered in one place, and from there, they return through the girdle surface. Excellent symmetry grade has a characteristic that releases more sparkle through pavilion anatomies with 75%.

Excellent symmetry grade is the superior symmetry grade of diamonds because in that grade the faceting proportions are matched each other at the same place

In excellent symmetry diamonds, diamond facets are placed in frequent numbers and with accuracy. Also, in excellent symmetry grade, there is no mistake found around the pavilion surface. Thus, select excellent symmetry-grade diamonds for engagement rings and other jewelry.

  • What is a very good symmetry grade?

In very good symmetry, a diamond reflects less light than an excellent-cut diamond. In very good symmetry grade diamonds, pavilion facets are not matched with each facet, but the ratio of mismatching is 1-3 numbers, so the faceting pattern doesn't affect the whole sparkling reflection.

When a diamond is placed under a fluorescence machine, the diamond can't be able to spark with pavilion facets then it has graded at very good symmetry. But, it still sparks full of reflections. As a result, very good symmetry grade diamonds get demand for necklaces and bracelets.

There is a minor difference in pavilion facets. In very good symmetry, light reflects another way from the diamond table surface.

Very good symmetry allows you to get budget freebies diamond because it carries low price with better appearance.

You can choose very good symmetry as the option for an excellent symmetry grade. Especially if you want a pendant or necklace with another shape of a diamond, then you can freely choose very good symmetry diamond.

  • What is a good symmetry grade in diamond? 

In a good symmetry diamond, the length of the pavilion facet is not long as in a very good symmetry diamond. Good symmetry diamond pavilion facets are not matched with each other, and they lose their sparkling ability due to cross patterns.

A good symmetry-grade diamond pavilion facets are not in their deserved place as proportions, which means facets are placed in the unrequired place.

Good Symmetry Diamond Grade has sometimes mismtached portions of faceting but it still used in engagement rings and wedding rings

On another side of the table surface, star and bezel facets are placed infrequently, a problem occurring when light enters through the diamond. In this good symmetry grade, the entered light cannot exit from the center table surfaces.

As a result, the diamond sparkles with less shining lights (with less scintillation). So, the good symmetry diamond is the best choice for a Halo style engagement ring.

  • What are fair symmetry grade diamonds?

Fair symmetry grade diamonds have less amount of pavilion facets. As a result, the sparkle reflection is very less than very good symmetry grade. In fair symmetry grade diamonds, the pavilion facets are not matched in one place, and they have no same proportions as described.

When rough diamonds are placed on the grading running wheel, then sometimes the scratches placed on the pavilion. Then facets of the pavilion do not gain sparkle, scales at fair symmetry grade diamonds.

First of all, we do not recommend this fair grade symmetry. So, When the diamond passes the making process and gains fair symmetry, it clearly hints diamond has a dull reflecting light ability. 

Fair Symmetry Grade is the example of mismatched portions on the pavilion faceting

When fair symmetry diamond has placed on a ring, whatever the style is. This diamond symmetry grade destroys the beauty of the ring and eyes. Also, in fair symmetry, a diamond has a flat crown surface with different facets that do not match each other. So, that is very obvious not to give the brilliance sparkle light.

  • What is a poor symmetry grade diamond?

When a diamond girdle has different faceting patterns on the pavilion anatomies and destroys the light reflection ability then it scales at poor symmetry diamond. Poor symmetry grade diamond represents the high thickness of the girdle, diamond anatomy placement not at deserving place. 

The reflection of light does not look beautiful, but it's dull and untransparent when a diamond scales at poor symmetry.

So, poor symmetry grade diamonds are not selected for engagement rings and wedding rings. But, when the budget is the problem when buying engagement rings, then poor symmetry grade diamonds are useful.

Poor Symmetry is the example of the mismatched faceting appearance in poor symmetry grade diamonds faceting is not matched


In poor symmetry of the diamond, light is reflected from its endpoint(Diamond Culet). It's not reflecting upward. Also, in poor grade symmetry, light is invisible from the culet side. In addition, the most important thing is that on the table surface of the diamond, the facets are placed anywhere. Here, problems occur with reflecting such a brilliant sparkling light.

So, poor symmetry is not recommended from our point of view and extensive experience with diamonds. Although, This symmetry is getting only 3% demand from customers.

  • Diamond expert words on symmetry grades

After you see the meaning of diamond symmetry and its type, you are aware of getting the right and accurate symmetry in diamond when purchase it. If you’re purchasing a loose diamond or diamond jewelry, ask the seller for certification of diamonds with authenticating institutes like GIA, IGI, EGL, and SGL.

A Certified diamond is described as having necessary or unrequired characteristics of a diamond. In certification, diamond symmetry is also shown for buyers to decide whether to purchase it or not. 

So, we can say that Diamond Symmetry leads from the front of the diamond overall glance.
