Understanding Inclusions and Clarity in Alexandrite
Alexandrite is a captivating gemstone known for its mesmerizing color-changing properties. Its ability to shift from a vibrant green in daylight to a deep red under incandescent light makes it a highly sought-after gem in the jewelry world. However, when shopping for alexandrite, it’s essential to understand the concept of inclusions and clarity, as they greatly impact the gem’s overall quality and value. In this article, we will delve into the world of alexandrite inclusions and clarity, providing you with valuable insights to make an informed purchasing decision.
What are Inclusions?
Inclusions refer to the naturally occurring internal characteristics found within a gemstone. These characteristics can include tiny crystals, minerals, or even gas bubbles that became trapped during the formation process. Inclusions are unique to each gemstone, acting as a fingerprint that distinguishes one from another. While inclusions are inherent in most gemstones, the type, size, and location of the inclusions directly impact a gem’s clarity.
Clarity Grading System
The Gemological Institute of America (GIA) has established a clarity grading system to assess the presence and visibility of inclusions in gemstones. This system ranges from Flawless (no inclusions or blemishes visible under 10x magnification) to Included (inclusions visible to the naked eye). For alexandrite, which is typically found with some degree of inclusions, the most common clarity grades are:
- Eye Clean: These gemstones have no visible inclusions to the naked eye and exhibit excellent clarity.
- Slightly Included: These gemstones may have minor inclusions visible under magnification but still possess good overall clarity.
- Heavily Included: These gemstones have significant inclusions that are visible to the naked eye, affecting their overall clarity and value.
Impact of Inclusions on Alexandrite
Inclusions in alexandrite can have various effects on the gem’s appearance and value. Some inclusions may create a hazy or cloudy appearance, reducing the gem’s transparency and brilliance. In contrast, certain inclusions can enhance the alexandrite’s unique color-changing properties, creating mesmerizing optical effects.
It’s important to note that not all inclusions are undesirable. Some collectors and enthusiasts appreciate unique inclusions as they add character and tell the story of the gem’s formation. Penultimately, the impact of inclusions on alexandrite depends on personal preferences and the gem’s intended use.
Choosing the Right Clarity Grade
When selecting an alexandrite gemstone, it’s crucial to consider the clarity grade that best suits your preferences and budget. If you prioritize a flawless appearance, opt for an eye-clean alexandrite with minimal inclusions. However, keep in mind that higher clarity grades often come with a higher price tag.
If you appreciate the gem’s color-changing properties and can tolerate minor inclusions, slightly included alexandrite may be a suitable choice. These gemstones offer a balance between value and visual appeal.
On the other hand, heavily included alexandrite may be more affordable but may not exhibit the same brilliance and transparency as higher clarity grades. Nonetheless, they can still possess a unique charm and be an excellent choice for those seeking a more budget-friendly option.
Expert Tips for Assessing Clarity
When evaluating the clarity of an alexandrite gemstone, consider the following expert tips:
- Examine the gemstone under proper lighting conditions to observe its color-changing properties and assess the visibility of inclusions.
- Use a jeweler’s loupe or magnifying glass to inspect the gemstone closely. This will help you identify any inclusions that may affect its overall appearance.
- Ask for a certificate of authenticity from a reputable gemological laboratory, such as the GIA or AGS, to ensure the accuracy of the clarity grade provided.
Summary

The presence and visibility of inclusions directly impact the gem’s overall appearance, value, and uniqueness. By considering the clarity grade and assessing the gemstone’s visual appeal, you can select an alexandrite that aligns with your preferences and budget.
