Like Earth-mined diamonds, lab diamonds are crafted through intense heat and pressure. As a result, these lab-made gems also have internal (inclusions) and external (blemishes) characteristics. These attributes, or lack thereof, determine a gemstone's Clarity Rating, ranging from Internally Flawless (IF) to Included (I3).

Read further below to learn about lab-grown diamond Clarity Ratings and find which one best fits your premium Engagement Ring, Wedding Band, or Fine Jewellery piece. 💍

How Exactly Does IGI Examine Lab Diamond Clarity?

According to the International Gemological Institute's (IGI) website, Clarity is observed based on the international standard of 10X magnification and graded according to inclusions and blemishes':

  • Visibility,
  • Size,
  • Number,
  • Location, and
  • Nature

Lab diamonds with immediately noticeable characteristics are candidates for lower grades. Meanwhile, those with minor, minute, or hard-to-spot inclusions qualify for higher Clarity ratings.

IGI's Lab Diamond Clarity Grades: A Complete List

Find the ethically made lab diamond gem that best represents your love. Here are IGI's Clarity Ratings, from the least up to the most amount of inclusions and blemishes. ✨

Flawless (F) to Internally Flawless (IF)

A Flawless Rating means that there is no inclusion seen at 10X magnification. On the other hand, IGI grades a gemstone with surface blemishes but no internal inclusions as Internally Flawless. These are the highest Clarity Ratings, best suited for a pure love that knows no bounds.

Very Very Slightly Included (VVS1, VVS2)

VVS grades have minute characteristics that are difficult to find at 10X magnification. VVS1 is closer to Flawless than VVS2. These lab-grown diamonds are perfect for a love that gives it all.

Very Slightly Included (VS1, VS2)

Meanwhile, VS Clarity Grades have minor inclusions or blemishes. VS1 Ratings and above are always eye-clean, meaning its characteristics are not visible to the naked eye. These gemstones match a love that is simple and true.

Slightly Included (SI1, SI2)

Right next comes Slightly Included Ratings with quickly noticeable characteristics at 10X magnification.

Included (I1, I2, I3)

Finally, lab diamonds marked as Included have large or abundant inclusions evident at 10X and even without magnification.
