The Difference Between Diamond Clarity Grades: Flawless, Internally Flawless, and More
What makes a diamond truly rare? Is it the size, the sparkle, or the shape? At the heart of it, one of the most defining factors is clarity, a measure of purity that reveals a diamond’s inner world. Every inclusion tells a story of the Earth’s forces, time, and transformation. But fewer inclusions? That’s where rarity begins.
At Laxmi Diamond, our unwavering commitment to excellence means that we study each diamond with meticulous precision. Our expert gemologists use global grading standards and advanced technology to ensure every diamond we offer is a perfect balance of nature and craftsmanship. In this blog, we break down what clarity grades really mean, from Flawless to Included, and why it matters to anyone who values true brilliance.
What is Diamond Clarity?
Clarity is the internal characteristics (inclusions) and external imperfections (blemishes) present within a diamond. These blemishes are formed organically during the process of the diamond's development—a natural progression underground that lasts millions of years. Although nearly every diamond contains some inclusions, it is the number, kind, size, location, and visibility of these imperfections that dictate its clarity grade.
Clarity is not simply a degree of beauty, it is an indicator of rarity. The fewer inclusions, the rarer the diamond.
Clarity Grades: From Flawless to Included
Diamond clarity is graded using a precise scale, ranging from Flawless (FL) to Included (I1, I2, I3). Here's a breakdown:
Flawless (FL)
❖ No internal or external imperfections visible under 10x magnification.
❖ Extremely rare (less than 1% of all diamonds).
❖ Represents the highest level of purity and perfection.
Internally Flawless (IF)
❖ No internal inclusions, but they may have minor surface blemishes.
❖ Still very rare and highly valuable.
Very Very Slightly Included (VVS1 & VVS2)
❖ Inclusions are extremely difficult to detect even under 10x magnification.
❖ Only visible to skilled professionals using magnification.
Very Slightly Included (VS1 & VS2)
❖ Minor inclusions that are difficult to see without magnification.
❖ Offers great value without compromising on appearance.
Slightly Included (SI1 & SI2)
❖ Inclusions are visible under 10x magnification and may be slightly visible to the naked eye.
❖ Often more budget-friendly with acceptable brilliance.
Included (I1, I2 & I3)
❖ Inclusions are obvious and may impact brilliance and durability.
❖ Generally used in commercial-grade jewellery.
Why Clarity Matters
Clarity impacts not just a diamond’s appearance, but also:
❖ Light performance –Fewer inclusions = better brilliance.
❖ Durability –Fewer internal flaws = stronger structure
❖ Value –Rarer diamonds hold more value
❖ Uniqueness –Every diamond's clarity fingerprint is one of a kind
The Laxmi Diamond Difference

❖ Our grading process goes beyond the traditional 4Cs. With the 5th C, conscious, we ensure that every diamond we deliver is a reflection of quality and integrity.
We understand that for every client, whether a jeweller, manufacturer, or buyer, clarity also means transparency in sourcing, grading, and ethics.
