Colombian emeralds are known worldwide for their stunning color and quality. However, the value of an emerald depends not only on its purity and color, but also on its cut.

A good cut can bring out the brilliance and beauty of the stone, while a bad cut can diminish its value.

In this article, we will explain how to evaluate the cut of a Colombian emerald and what to do if the cut is not right.

Types of emerald cuts

Before learning how to evaluate the cut, it is important to know the most common types of emerald cuts. Here are some of the most popular ones:

1. Emerald Cut : This is the most typical cut, with a rectangular or square shape, with beveled corners. This cut allows for better light distribution.
2. Oval Cut : Highlights the length of the emerald and can make the stone appear larger.
3. Round Cut : Although less common in emeralds, it is ideal for those who prefer a more traditional shape.
4. Teardrop Cut : It has an elongated shape with a pointed end, very elegant.
5. Princess Cut : It is square or rectangular with more defined corners than the emerald cut.

Step by step: How to evaluate the cut of an emerald?

1. Symmetry and Proportions : A good cut should be symmetrical, meaning that all sides of the emerald should be proportional in shape and size. Examine whether the stone looks balanced from all angles.
2. Facet Alignment : Look to see if the facets (polished surfaces) are aligned evenly. The facets should reflect light evenly, without shadows or dull areas.
3. Pavilion Flatness : The pavilion is the bottom of the emerald. Make sure it is not too flat or too deep, as both can affect the brilliance of the stone.
4. Polishing : A good polish is essential to ensure that light is reflected properly. Check the surface for visible scratches, rough spots or marks.
5. Check for crookedness : Hold the emerald at a right angle and make sure the stone is completely aligned and not crooked. A crooked cut will negatively affect the symmetry and brilliance of the emerald.

What to do if my emerald has a bad cut?

If you find that your Colombian emerald has a flawed cut, you have a few options:

1. Consult a professional gemologist : A gemologist can assess the damage and determine if the cut can be improved without affecting the integrity of the stone.
2. Re cutting : In some cases, it is possible to re cut the emerald to correct flaws in the cut. This may involve losing some weight, but will improve the brilliance and appearance of the stone.
3. Sell ​​or Trade : If re cutting is not an option, you may consider selling or trading the emerald.
