What is Clarity of a Colombian emerald?

The Colombian emerald is one of the most coveted gemstones in the gem market for its unique beauty and intense green color. However, for collectors and jewelers, one of the most important aspects to consider is the clarity of the emerald.

In this article, we will explore in depth what is clarity in an emerald, the different types of clarity that exist, how they are evaluated and how they influence the price of this dazzling gem.

What is Clarity in an Emerald?

Clarity refers to the presence of inclusions and internal spots in a gem. In the case of Colombian emeralds, these inclusions are a natural and expected characteristic, and are commonly known as gardens. These imperfections can affect the transparency and general aesthetics of the stone.

Types of Clarity in the Emeralds

Emeralds are classified into different categories of clarity, which are based on the quantity, size and type of inclusions present. Here is a general guide to understanding these types:

  1. Transparent: These emeralds have little or no visible inclusion with the naked eye. They are extremely rare and therefore very valuable.
  2. Slightly Inclusive: The inclusions are minimal and are noticed only under a close observation. These emeralds maintain high transparency and significant value.
  3. Moderately Inclusive: They present more remarkable inclusions that can affect the transparency of the stone somewhat. Despite this, they still have considerable value.
  4. Severely Inclusive: The inclusions are evident and significantly affect the clarity of the emerald. This type of clarity can reduce the value of the gem, although some inclusions may add character.
  5. Opaque: Opaque emeralds have severe inclusions that prevent you from seeing through the stone. These emeralds have the lowest value due to their lack of transparency.

How is the Clarity of an Emerald Evaluate?

The assessment of the clarity of an emerald is done using a grove microscope, where experts can examine the stone at the level of increase. The position, size, quantity and type of inclusions are analyzed to determine the gem's clarity category. In addition, gemologists also consider the influence of inclusions on the brightness and emerald coloring.

Price vs. Clarity in an Emerald

The price of a Colombian emerald is closely linked to its clarity. Overall, emeralds with fewer inclusions and greater transparency have a higher price. However, the value also depends on other factors, such as the color and size of the gem. It is important to note that, although high-slight emeralds are highly desirable, some inclusions can be acceptable and even appreciated if they add a unique character to the stone.

How to know the Clarity in an Emerald

  1. Send from the Emerald to the Laboratory: The first step in the certification process is to send the emerald to an accredited gemological laboratory. It is important that the laboratory be recognized and respected in the industry to ensure the accuracy and integrity of the report.
  2. Initial Visual Inspection: Once the emerald arrives at the laboratory, gemologists perform an initial visual inspection using magological magic and microscopes. This allows them to identify the inclusions visible to the naked eye and make a preliminary assessment.
  3. Analysis with Specialized Microscopes: Gemologists use high-power microscopes to examine emerald in more detail. This analysis allows you to observe small inclusions and other internal characteristics that affect clarity. Inclusions can be of different types, such as gas bubbles, fractures or trapped minerals.
  4. Clarity Assessment : Based on observations, gemologists classify the clarity of emerald on a predefined scale, which may vary slightly between different laboratories. This classification can be transparent, slightly inclusive, moderately, severely inclusive or opaque, as described above.
  5. Documentation and preparation of the Report: Once the evaluation has been carried out, the laboratory prepares a detailed report that includes the classification of clarity, along with additional information on the color, cutting and weight of the emerald. The report may also include photographs and diagrams showing the location and type of inclusions.
  6. Delivery of the Certificate: Finally, the report and the certificate are delivered to the customer. This document serves as official proof of clarity and other emerald characteristics, providing a solid basis for your purchase, sale or valuation.
