Lab diamond Clarity guide

Diamond clarity is a term used to describe the absence or presence of inclusions or blemishes in lab made diamonds. The clarity of a diamond is one of the factors that determine its value, with higher clarity diamonds being more valuable than lower clarity diamonds.

Here’s a guide to diamond clarity:

  1. Clarity Scale: The clarity of a diamond is measured on a scale ranging from Flawless (FL) to Included (I3). The clarity grades from highest to lowest are: Flawless (FL), Internally Flawless (IF), Very Very Slightly Included (VVS1 and VVS2), Very Slightly Included (VS1 and VS2), Slightly Included (SI1 and SI2), and Included (I1, I2, and I3).
  2. Inclusions: Inclusions are internal flaws that are usually created during the formation process of a diamond. They can be in the form of crystals, clouds, feathers, or other mineral deposits. Inclusions can affect the brilliance and clarity of a diamond, and also impact its durability.
  3. Blemishes: Blemishes are external flaws that are usually caused during the cutting and polishing process of a diamond. They can be in the form of scratches, nicks, pits, or extra facets. Blemishes can also impact the brilliance and clarity of a diamond.
  4. Eye Clean: A diamond that is “eye clean” has no visible inclusions or blemishes when viewed with the naked eye. An eye clean diamond is a good choice if you want to maximise the diamond’s visual appeal while staying within a reasonable budget.
  5. Importance of Clarity: The clarity of a diamond is one of the four Cs of diamond quality, along with carat weight, colour, and cut. The higher the clarity grade, the more valuable the diamond is likely to be. However, the importance of clarity can vary depending on the size and colour of the diamond, as well as personal preferences.
  6. Certification: It is important to purchase a diamond that has been certified by a reputable gemological laboratory, such as the Gemological Institute of America (GIA) or the American Gem Society (AGS). The certification should include the diamond’s clarity grade, as well as other important information about the diamond’s quality.
  7. Diamond Fluorescence: Some diamonds may exhibit fluorescence, which is a characteristic that causes the diamond to emit a visible glow when exposed to ultraviolet light. Fluorescence can affect the appearance and value of a diamond, so it is important to consider this factor when evaluating diamond clarity.
  8. Diamond Shape: The clarity of a diamond can also be affected by the shape of the stone. For example, emerald and Asscher cut diamonds are more transparent and therefore tend to show inclusions more easily. On the other hand, round brilliant cut diamonds tend to hide inclusions more effectively.
  9. Personal Preferences: Ultimately, the importance of diamond clarity is a matter of personal preference. Some people prioritise diamond clarity above all other factors, while others may be more concerned with the size or overall appearance of the diamond. It is important to choose a diamond that meets your specific needs and preferences.
  10. Maintenance: Finally, it is important to take good care of your diamond to maintain its clarity over time. Regular cleaning and inspections by a professional jeweller can help to prevent damage and preserve the beauty of your diamond.

In conclusion, the clarity of a diamond is an important factor to consider when purchasing a diamond. By understanding the clarity scale and what inclusions and blemishes are, you can make an informed decision when choosing a diamond that fits your budget and preferences.
