The Secret Behind Your Stone’s Uniqueness

Did you know that no two diamonds are exactly alike? It's true! Each diamond holds tiny marks inside, called inclusions, that make it uniquely yours. While flawless diamonds get plenty of attention, most diamonds actually have inclusions—and that can be a wonderful thing!

Let's dive into what inclusions really are, how they impact a diamond’s value, and why understanding them helps you make smarter choices when shopping for your perfect gem.

What Exactly Are Diamond Inclusions?

Inclusions are little quirks that naturally form inside a diamond as it grows deep within the Earth. Think of them as a diamond’s birthmarks, featuring:

  • Included crystals – tiny minerals trapped inside

  • Feathers – small breaks or fractures

  • Clouds – clusters of microscopic dots creating a misty look

  • Needles – slender, rod-like inclusions

  • Graining – subtle internal lines from irregular growth

These features don’t just add personality—they also help experts identify your diamond and confirm it's natural.

Why Do Inclusions Matter, Anyway?

Clarity is one of the famous 4Cs (color, cut, clarity, and carat weight) used to grade diamond quality. Inclusions play a key role in clarity, impacting the diamond’s price. But don’t worry! Many inclusions are invisible to the naked eye and won’t affect how your diamond sparkles.

The 5 Key Factors Gemologists Check

When grading clarity, gem experts look at:

  • Size – bigger inclusions mean lower clarity grades

  • Number – more inclusions might lower clarity

  • Location – inclusions under the diamond’s center are more noticeable

  • Relief – higher contrast inclusions stand out more

  • Nature – some inclusions (like large feathers) can affect durability

High Clarity Grades: Diamonds at Their Purest

GIA clarity grading goes from flawless to visibly included. Top grades include:

  • Flawless (FL) – absolutely no inclusions or marks visible under magnification

  • Internally Flawless (IF) – no internal inclusions, just minor surface blemishes

  • Very, Very Slightly Included (VVS1 & VVS2) – inclusions so tiny they're nearly impossible to spot

These are exceptionally rare and command premium prices.

Everyday Clarity Grades: Beauty Meets Value

Most diamonds you’ll find fall into these categories, which offer excellent beauty at practical prices:

  • Very Slightly Included (VS1 & VS2) – tiny inclusions, tough to see even with magnification

  • Slightly Included (SI1 & SI2) – visible at 10x magnification, typically invisible without

  • Included (I1, I2 & I3) – noticeable inclusions that might affect transparency or durability

VS2 and SI1 diamonds often look flawless once set—perfect for those who want brilliance without overspending.

Can Inclusions Actually Be Good?

You bet! Inclusions can:

  • Confirm your diamond is natural, not synthetic

  • Give your diamond a unique "fingerprint"

  • Tell the fascinating story of its formation deep within the Earth

No two diamonds have the same inclusions in the exact same spots, making yours truly one-of-a-kind.
