When shopping for or learning about diamonds, the term "inclusions" often arises as part of the diamond grading process. But what exactly are inclusions, and how do they affect a diamond’s beauty, quality, and value? At Concierge Jewelry Repair, we specialize in caring for diamonds with precision and expertise, ensuring their brilliance remains uncompromised. In this guide, we’ll explore what inclusions are, their types, and how they impact a diamond’s appearance and durability.

Defining Inclusions in Diamonds

Inclusions are natural imperfections or features found within a diamond. These can form during the diamond’s crystallization process deep within the Earth. Think of them as nature's fingerprints—unique marks that tell the story of the diamond’s formation.

While inclusions are often considered flaws, they are a normal part of most diamonds and vary in size, type, and visibility. In some cases, they are so minor that they require magnification to detect, while in others, they may be visible to the naked eye.

Types of Inclusions and What to Look For

Familiarizing yourself with common inclusion types will help you identify those that may or may not affect a diamond’s beauty and durability.

1. Pinpoints

  • Description: Tiny spots inside the diamond, usually only visible under magnification.

  • What to Consider: Pinpoints are generally harmless and have minimal impact on the diamond’s brilliance.

2. Feathers

  • Description: Internal cracks that resemble feathers under magnification.

  • What to Consider: Feathers near the surface can weaken the diamond, so opt for stones where feathers are small and positioned deeper within the diamond.

3. Crystals

  • Description: Mineral deposits trapped inside the diamond, which can be clear, white, or dark.

  • What to Consider: Dark or colored crystals are more noticeable and can detract from the diamond’s appearance.

4. Clouds

  • Description: Groups of pinpoints that create a hazy or cloudy effect.

  • What to Consider: Look for diamonds with minimal clouding, as significant clouds can dull the stone’s brilliance.

5. Needles

  • Description: Long, thin inclusions resembling tiny needles.

  • What to Consider: These inclusions are usually inconspicuous unless they are clustered.

How Do Inclusions Affect a Diamond’s Quality?

The presence and visibility of inclusions influence a diamond’s clarity grade, which is one of the 4Cs (cut, color, clarity, carat) used to evaluate diamonds.

Clarity Grades

Clarity grades, as defined by gemological institutions, range from Flawless (FL) to Included (I):

  • Flawless (FL) and Internally Flawless (IF): No visible inclusions under 10x magnification.

  • Very Slightly Included (VS1–VS2): Minor inclusions that are difficult to see under 10x magnification.

  • Slightly Included (SI1–SI2): Noticeable inclusions under magnification, sometimes visible to the naked eye.

  • Included (I1–I3): Inclusions are clearly visible, potentially affecting the diamond’s brilliance and durability.

Impact on Appearance

Larger or darker inclusions can interfere with a diamond’s ability to reflect light, diminishing its sparkle.

Impact on Value

Inclusions directly affect the diamond’s value. Flawless diamonds are the rarest and most expensive, while diamonds with visible inclusions are more affordable.

Tips for Choosing a Diamond Based on Inclusions

When selecting a diamond, inclusions are not necessarily deal-breakers. The key is understanding which inclusions matter and how to prioritize them based on your preferences and budget.

1. Prioritize Eye-Clean Diamonds

An "eye-clean" diamond is one where inclusions are not visible to the naked eye. These diamonds strike an excellent balance between clarity and value, especially in the VS or SI clarity grades.

2. Consider Placement of Inclusions

Inclusions near the edges of the diamond are less noticeable and can often be hidden by the setting. Avoid diamonds with inclusions in the center, as they are more likely to affect brilliance and visibility.

3. Evaluate the Type of Inclusions

Not all inclusions have the same impact. Small pinpoints or needles are less concerning than feathers or large crystals that can weaken the diamond’s structure.

4. Focus on Brilliance Over Perfection

A diamond’s cut has a more significant impact on its brilliance than clarity alone. A well-cut diamond can mask minor inclusions, so prioritize excellent or very good cut grades.

5. Work with a Trusted Jeweler

Choosing a diamond is easier with the guidance of a professional. At Concierge Jewelry Repair, we provide expert advice and transparency, helping you evaluate inclusions and make a confident choice.

Settings That Complement Inclusions

The right setting can minimize the visibility of inclusions and enhance the diamond’s overall appearance.

  • Halo Settings: Surrounding the center stone with smaller diamonds draws attention away from inclusions.

  • Bezel Settings: A metal rim encases the diamond, hiding inclusions near the edges.

  • Pavé Bands: Rows of smaller diamonds add extra sparkle, creating a distraction from minor flaws.
