Symmetry
The importance of symmetry in diamonds is key to unlocking the maximal brilliance and shine that makes the gem the beauty it is.
Diamond symmetry refers to how well the facets, the various parts of a diamond, interact and are positioned in relation to each other. While not part of the 4C’s, it is still a significant factor in diamond selection. The grading scale for diamond symmetry ranges from Poor to Excellent. An Excellent grade signifies superior symmetry, while a lower grade suggests variations in facet sizes or misalignment of the culet and table. Such imperfections can impact the diamond's visual appeal. Continue reading for expert advice on this topic.

Grading
It is essential to have at least a Very Good symmetry for a symmetric stone. Many pay extra for an Excellent symmetry. At VANBRUUN we do not recommend our customers to pay this amount as long as the final cut is graded to Excellent. r the color
Visual appeal
When buying a diamond, the most crucial consideration is how it appears. Symmetry, along with other factors like cut, clarity, color, and carat weight, plays a significant role in ensuring optimal visual appeal and value. This is particularly true for step-cut diamonds such as emeralds and asschers, where symmetry is revealed easily.
Facets and aligment
Facet sizes are crucial for balanced light dispersion in a diamond. Uniformly sized facets result in optimal brilliance, fire, and scintillation. Irregular sizes can cause inconsistent appearance, while evenly sized facets exhibit superior beauty and are highly valued for their exceptional optical performance.

The 4C's
A diamond is graded by four parameters called the 4C's. Together they determine the look and price of a diamond. Read on to learn more about the 4C's.
Cut
Determine how light is reflected. This is the most critical parameter to have in mind.
Clarity
Describes the absence or presence of imperfections, their position, size, and origin.
