Do lab grown diamonds have inclusions

Lab-grown diamonds can have inclusions, just like natural diamonds. Inclusions are small imperfections or internal features within a diamond that can affect its clarity and appearance. These inclusions can be composed of various materials, such as other diamond crystals, minerals, or other substances. The presence of inclusions can influence the diamond’s value and visual characteristics.

Here’s a detailed explanation of inclusions in lab-grown diamonds:

Formation of Inclusions: Inclusions in lab-grown diamonds can form during the diamond growth process. When a diamond is grown in a laboratory, carbon atoms are arranged in a crystal lattice structure, just like in natural diamonds. However, the growth conditions, impurities in the growth environment, and other factors can lead to the incorporation of foreign materials or irregularities in the crystal lattice, resulting in inclusions.

Types of Inclusions: Inclusions in both natural and lab-grown diamonds can take various forms, including:

  • a. Pinpoints: Tiny crystals or mineral inclusions that are often only visible under magnification.
  • b. Clouds: Clusters of tiny pinpoint inclusions that can create a hazy or cloudy appearance within the diamond.
  • c. Feathers: Small cracks or fractures within the diamond.
  • d. Needles: Long, needle-like inclusions that can be composed of various materials.
  • e. Twinning Wisps: These are complex inclusions that result from twinning planes within the diamond’s crystal structure.

Impact on Clarity: Inclusions can affect the clarity grade of a lab-grown diamond, just as they do with natural diamonds. The clarity grade is determined by the number, size, type, and visibility of these inclusions. Diamonds with fewer and less visible inclusions are considered to have higher clarity grades and are generally more valuable.

Enhancement and Treatment: Some lab-grown diamonds undergo treatments to improve their clarity. For example, laser drilling can be used to remove certain types of inclusions or fractures, making them less visible. This process is similar to treatments applied to some natural diamonds.

Inclusions as Identification: In some cases, inclusions can be used as a means of identifying whether a diamond is lab-grown or natural. Certain types of inclusions or growth patterns can be indicative of a diamond’s origin.

It’s important to note that lab-grown diamonds are not necessarily free from inclusions. The quality and clarity of a lab-grown diamond can vary, just as with natural diamonds. Buyers should consider factors like clarity, color, cut, and carat weight when evaluating the overall quality and value of a lab-grown diamond, and they should obtain a grading report from a reputable gemological laboratory to understand the specific characteristics and any inclusions in the diamond they are considering.
