What are Inclusions in Diamonds?

When choosing a diamond, terms like “clarity” and “inclusions” are essential to understand. Inclusions, often called the “fingerprints of nature,” are natural characteristics that form within a diamond as it develops over millions of years. These unique internal features make each diamond one of a kind. At Calvin’s Fine Jewelry, we believe in helping our clients make informed choices, so let’s dive deeper into what inclusions are and how they impact the beauty and quality of your diamond.

1. Understanding Diamond Inclusions

Inclusions are internal marks, such as tiny crystals, feathers, or clouds, that occur naturally within a diamond. They form deep within the earth under immense heat and pressure, giving each diamond its unique character. While these natural characteristics may seem like imperfections, they actually make each diamond unique, adding to its story and personality.

  • Inclusions vs. Blemishes: Inclusions are internal, while blemishes are external marks on a diamond’s surface. In this blog, we’ll focus specifically on inclusions and their influence on diamond clarity and appearance.

2. Types of Inclusions

There are several types of inclusions, each affecting a diamond’s clarity and appearance in different ways. Here’s a breakdown of some common inclusions you may encounter:

  • Crystals: Tiny mineral crystals, often other diamonds or minerals, trapped inside the diamond. They can vary in size and color.
  • Feathers: Small fractures within the diamond that resemble feathers. These are typically invisible to the naked eye and usually only visible under magnification.
  • Clouds: A cluster of pinpoints that appear as a hazy or cloudy area inside the diamond, often impacting clarity depending on their size and placement.
  • Pinpoints: Tiny white or black specks within the diamond. A single pinpoint is usually insignificant, but a cluster of them can create a cloudy effect.
  • Needles: Thin, elongated inclusions that resemble tiny needles. These are often very small and hard to detect without magnification.

Each type of inclusion contributes to a diamond’s overall clarity grade, which plays a role in its beauty and value.

3. The Clarity Grade and How It’s Determined

The clarity grade is a measurement of the presence and visibility of inclusions and blemishes within a diamond. The Gemological Institute of America (GIA) grades diamonds based on clarity, ranging from Flawless (no visible inclusions or blemishes under 10x magnification) to Included (where inclusions are visible to the naked eye).

The GIA clarity scale includes:

  • FL (Flawless): No inclusions or blemishes visible under 10x magnification.
  • IF (Internally Flawless): No inclusions visible under 10x magnification; minor surface blemishes may exist.
  • VVS1 - VVS2 (Very Very Slightly Included): Inclusions are extremely difficult to see under 10x magnification.
  • VS1 - VS2 (Very Slightly Included): Minor inclusions that are difficult to see under 10x magnification.
  • SI1 - SI2 (Slightly Included): Inclusions that are visible under 10x magnification and may or may not be visible to the naked eye.
  • I1 - I3 (Included): Inclusions visible to the naked eye that may affect transparency and brilliance.

At Calvin’s Fine Jewelry, we offer a range of diamonds across these clarity grades, and our GIA-certified experts can help you understand which grade aligns with your preferences.

4. How Inclusions Affect a Diamond’s Appearance

Inclusions can influence a diamond’s appearance in several ways, from its overall sparkle to its perceived clarity. Here’s how:

  • Impact on Sparkle: Large or prominent inclusions can disrupt the way light passes through a diamond, slightly diminishing its sparkle and brilliance. However, smaller inclusions that are well-placed may have minimal effect.
  • Visible vs. Invisible Inclusions: Inclusions that are small or strategically located near the edge (girdle) of the diamond are often invisible to the naked eye, allowing for a beautiful diamond at a more accessible price point.
  • Transparency and Luster: Dense clusters of inclusions, like clouds, can impact transparency, giving a diamond a less clear, hazy look. Most inclusions, though, are hardly noticeable without magnification.

Understanding these factors allows you to prioritize what matters most for your diamond purchase.

5. Evaluating Eye-Clean Diamonds

An “eye-clean” diamond is one where inclusions are not visible to the naked eye. Many diamonds graded VS1, VS2, and even some SI1 diamonds fall into this category, offering a beautiful balance between clarity and cost.

What Makes a Diamond Eye-Clean? The size, location, and type of inclusion affect whether it’s visible without magnification. For example, small pinpoints or inclusions near the girdle may not affect a diamond’s appearance.

At Calvin’s Fine Jewelry, we help you evaluate eye-clean diamonds that maximize both beauty and value. Our experts are here to guide you toward diamonds that meet your clarity preferences without sacrificing aesthetic appeal.

6. The Role of Magnification in Seeing Inclusions

At Calvin’s, we use magnification tools, such as loupes and microscopes, to reveal inclusions in detail. This allows you to understand the unique characteristics of each diamond and make an informed decision.

  • Why Use Magnification? Magnification provides insight into a diamond’s internal structure, revealing inclusions that may be invisible to the naked eye. This practice is standard in the industry to ensure clarity grading accuracy.
  • Guided by Experts: Our GIA-certified experts at Calvin’s use these tools to walk you through the clarity evaluation, explaining each inclusion's impact on the diamond’s overall beauty.

7. How Inclusions Affect Diamond Value

Inclusions directly affect a diamond’s clarity grade, which in turn influences its value. Flawless and Internally Flawless diamonds are rare and therefore command premium prices. However, diamonds with inclusions that are difficult to see with the naked eye offer excellent value without compromising beauty.

  • Value in Different Clarity Grades: VS1 and VS2 diamonds are popular choices for their nearly flawless appearance to the naked eye, offering beauty without the premium cost of a flawless diamond.
  • Budget-Friendly Options: SI1 and SI2 diamonds can offer stunning beauty at a more accessible price, especially when inclusions are minimal or located in less visible areas.

At Calvin’s, we help you find a diamond with the best balance of clarity and value, offering clarity grades that meet both budget and aesthetic preferences.

8. Choosing the Right Clarity for Your Needs

Selecting the right clarity grade depends on your personal preferences and budget. At Calvin’s, we encourage clients to prioritize what’s most important—whether it’s having a diamond free of visible inclusions or opting for one that offers a balance between beauty and affordability.

  • High Clarity for Maximum Brilliance: If you value a high-clarity diamond, a grade like VVS1 or VVS2 offers minimal inclusions and beautiful brilliance.
  • Eye-Clean Choices for Value: For those seeking a diamond that looks flawless to the eye without the high cost, VS2 or SI1 are great options.

Our experts at Calvin’s can guide you through these options, helping you choose a diamond with the perfect clarity for your unique vision.

9. Inclusions and the Unique Character of a Diamond

While some view inclusions as imperfections, they’re also what make each diamond one of a kind. Every diamond has a story of formation, and inclusions are like natural markers of its journey.

  • Nature’s Signature: Just as no two fingerprints are the same, each diamond’s inclusions are unique, giving it a signature look that adds to its character and individuality.
  • A Personal Choice: For some, knowing a diamond has unique inclusions adds to its appeal. Calvin’s clients often enjoy selecting a diamond that stands out, choosing stones that embody nature’s artistry.
