The Diamond Clarity Scale
The Gemological Institute of America (GIA) created the clarity scale that grades diamonds from “Flawless (FL)” to “Included (I3)”. To assign these grades, professionals use 10× magnification to examine a stone’s internal and external characteristics — details far too small to see with the naked eye.
| FL IF | VVS1 VVS2 | VS1 VS2 | SI1 SI2 | I1 I2 I3 |
| Internally Flawless | Very Very Slightly Included | Very Slightly Included | Slightly Included | Included |
Choosing a Clarity Grade
When it comes to the 4Cs, the balance between budget, beauty, and lifestyle is key. For those seeking rarity, a D-colour, Flawless (FL) diamond is unmatched in purity — and represents an exceptional investment. However, it’s important to understand that different diamond cuts reveal inclusions differently. Cuts with many small facets, such as radiant or brilliant shapes, reflect light in ways that disguise minor imperfections. In contrast, emerald cuts have large, open facets that can make inclusions more visible, requiring a higher clarity grade for a clean appearance. If you’re working within a set budget, focus on finding a diamond that is “eye-clean.” For example, a VS1 diamond may technically contain inclusions, but they are invisible to the naked eye — allowing you to choose a larger stone without compromising on sparkle or durability. If size remains a priority, consider lab-grown diamonds. Because they are created under controlled conditions that replicate the natural growth process, they often achieve D-F colour and IF to VS1 clarity — delivering exceptional quality with a more accessible price point and a lighter environmental footprint.

Finding the Right Balance
Selecting the perfect diamond is about more than technical grades — it’s about proportion, style, and how the stone makes you feel. Think about what matters most to you: scale, cut, brilliance, or clarity. Complex shapes like emerald or heart cuts demand expert craftsmanship and often benefit from higher clarity to protect against internal weaknesses. Whenever possible, view your diamond in person or via high-quality video to appreciate how it performs in real light. This is the most authentic way to see its fire, brilliance, and character — ensuring it aligns with your vision for a piece you’ll wear for years to come. At Norrfolks, our experts hand-select each diamond to ensure exceptional purity and performance, whether you choose from our curated selection or prefer to handpick your own. The goal is simple: to find the diamond that feels like it was made for you — beautifully balanced, timeless, and true to the understated elegance of Scandinavian design.
