I3 diamonds are the lowest clarity grade on the GIA scale, with very obvious inclusions that can be easily observed with the naked eye without magnification. Therefore, I3 diamonds have the lowest selling price among all clarity grades, often used in popular jewelry lines or mass-market fashion jewelry.
However, with many aesthetic and durability limitations, I3 diamonds are not suitable for investment and are usually not chosen by high-end jewelry brands.
In this article, you will gain a deeper understanding of what I3 diamonds are, their characteristics, prices, and whether you should choose to buy this type of diamond.
What are Natural I3 Diamonds?
I3 diamonds (Included 3) are diamonds with the highest level of inclusions, belonging to the I (Included) group - the lowest clarity group on the GIA scale. I3 diamonds typically have:
- Very obvious internal and/or external inclusions, which can affect the stone's durability.
- Poor light reflection, causing the diamond to lack natural sparkle.
- Prone to chipping or cracking if subjected to strong impact due to unstable structure.
I3 diamonds are suitable for low-cost jewelry, but are not recommended for wedding rings, asset investment, or high-end jewelry design.
