Diamond Clarity

When it comes to diamonds, clarity is an important factor that affects both the visual appeal and the value of the stone. A diamond's clarity is determined by the presence or absence of inclusions—tiny natural imperfections that occur within the diamond during its formation. These inclusions can take the form of crystals, clouds, or tiny rivers, and though they are often invisible to the naked eye, they can impact the diamond's brilliance and overall beauty. The clearer the diamond, the more light it can reflect, which leads to greater sparkle and brilliance.

Clarity Grading Scale

Diamonds are graded on a scale that ranges from FL (Flawless) to I3 (Included). Here's a breakdown of each clarity grade:

-FL (Flawless):

These diamonds show no inclusions or blemishes of any kind when observed under a 10x magnification by an experienced grader. Flawless diamonds are extremely rare and are considered the pinnacle of perfection in the diamond world.

-IF (Internally Flawless):

An internally flawless diamond shows no inclusions under 10x magnification, but may have minor surface blemishes. While not as rare as flawless diamonds, they are still highly valuable and offer exceptional clarity.

-VVS1, VVS2 (Very Very Slightly Included):

Diamonds with very, very small inclusions that are difficult to detect even for an experienced grader under 10x magnification. These diamonds offer exceptional clarity and brilliance, with only the most trained eyes able to spot any inclusions.

-VS1, VS2 (Very Slightly Included): 

Slight inclusions that can only be seen under 10x magnification by an experienced grader. These diamonds still possess excellent clarity and brilliance, offering great value while being slightly more affordable than the higher-grade diamonds.

-SI1, SI2 (Slightly Included):

Diamonds with small inclusions that are noticeable under 10x magnification. These diamonds may not have the same brilliance as higher-clarity diamonds, but they still offer tremendous value and are a popular choice for those seeking an affordable yet stunning diamond.

-I1, I2, I3 (Included):

These diamonds have inclusions that are visible to the naked eye and can affect the stone's brilliance. These diamonds are generally not recommended for engagement rings due to their reduced sparkle and lower clarity. At Milanj Diamonds, we do not recommend diamonds graded I1 or lower for engagement rings.

The Importance of Clarity

The clarity of a diamond plays a key role in its overall beauty. While inclusions may be invisible to the naked eye, they are still present within the diamond, affecting how light is refracted through the stone. Fewer inclusions lead to a greater ability to reflect light, creating a diamond with higher brilliance and sparkle.

While internally flawless diamonds are incredibly rare, diamonds with small inclusions, such as those graded VS or SI, still offer excellent value and can be stunning in appearance when properly cut. Choosing a diamond with good clarity ensures that it will shine brightly, showcasing its natural beauty.

Milanj Diamonds' Recommendations
