Diamonds form under intense pressure, which naturally results in imperfections, known as characteristics or inclusions. These unique traits are assessed using a clarity scale that ranges from slightly included (SI) to flawless (FL), part of the 4Cs of diamond grading. While internal inclusions and surface blemishes may exist, most are not visible without magnification and don’t diminish a diamond’s beauty. Diamonds with fewer visible imperfections receive higher clarity grades and come with higher price tags. Remember, every diamond is one of a kind, imperfections and all!
Tips for Understanding Diamond Clarity
Misconceptions around clarity often lead people to believe that higher clarity always equals more sparkle — this is not true! Many inclusions, especially in grades like SI (Slightly Included) and VS (Very Slightly Included), are so small they’re invisible to the naked eye, making these diamonds a fantastic choice for balancing beauty and budget. Keep in mind, diamond shape and size can influence clarity; larger diamonds or step cuts like emerald or Asscher may require higher clarity grades to avoid visible inclusions.
Ultimately, clarity is one of many factors to consider when finding your perfect diamond.
The Diamond Clarity Scale: 11 Grades of Beauty
Diamond clarity is evaluated on an 11-grade scale, from slightly included to flawless. This standard, established by Richard T. Liddicoat and the GIA in 1953, categorizes diamonds into six groups based on their clarity ratings.
A higher clarity grade means a diamond is less included and, therefore, more valuable. For example, diamonds graded as SI will be priced lower than those rated VVS because SI diamonds show more visible inclusions. Delorenzo Diamonds only offers diamonds above the included grade, ensuring quality in our selection.
Diamond Clarity Grades Explained
Included (I1, I2, I3): Noticeable inclusions that affect beauty; Delorenzo Diamonds does not sell these for engagement rings but offers limited preset jewelry.
Slightly Included (SI1, SI2): Inclusions are detectable at 10x magnification; often, they offer great value if eye clean.
Very Slightly Included (VS1, VS2): Minor inclusions; a popular choice for great value.
Very, Very Slightly Included (VVS1, VVS2): Inclusions are hard to see even under magnification; these diamonds appear eye clean.
Internally Flawless (IF): No inclusions but minor surface blemishes; visually clean.
Flawless (FL): No visible characteristics; less than 1% of diamonds fall into this rare category.
Five Factors Affecting Clarity
Size: Larger inclusions lower clarity.
Number: Fewer visible characteristics lead to higher grades.
Position: The location of inclusions impacts visibility and clarity.
Nature: The type of inclusion affects durability.
Color and Relief: The contrast between characteristics and the diamond can influence how noticeable they are.
Why SI and VS Diamonds Offer Exceptional Value
While Flawless (FL) and Internally Flawless (IF) diamonds represent the pinnacle of clarity, they can be prohibitively expensive. For outstanding value, consider diamonds with SI or VS clarity grades. These diamonds often have inclusions that are invisible to the naked eye, making them visually indistinguishable from higher-grade diamonds while being more budget-friendly.
How Diamond Shape Affects Clarity
Certain diamond shapes, like Emerald and Asscher cuts, require a higher clarity grade because their step-cut facets reveal inclusions more readily. For these shapes, aim for a VS1 clarity grade or better. In contrast, brilliant-cut shapes like Round or Princess may conceal inclusions more effectively, allowing for a lower clarity grade without compromising beauty.
The Impact of Size on Clarity
As a diamond’s size increases, its facets also grow larger, making inclusions more noticeable. Thus, it's essential to choose a higher clarity grade for larger stones to maintain their visual appeal.
Understanding the Diamond Clarity Plot
Diamonds over one carat come with a clarity plot in their GIA grading report, detailing the stone’s inclusions, blemishes, and characteristics that influenced its grading.
Popular Diamond Clarity Choices
With a range of price points, SI1 and SI2 diamonds are excellent entry-level options, offering beauty with minimal visible inclusions. Delorenzo Diamonds’ VS and SI diamonds are particularly favored for their balance of quality and affordability. As a rule, smaller diamonds tend to hide blemishes better, making clarity a crucial consideration for larger stones.
Learning About Diamond Characteristics
Inclusions and blemishes not factored into a diamond's grade can still be noted on the GIA report or clarity plot, which is included for diamonds over one carat.
Exploring the Different Types of Diamond Inclusions and Blemishes
If you're intrigued by the internal and external characteristics of diamonds, you'll appreciate the variety of inclusions and blemishes that can enhance their uniqueness.
Types of Diamond Inclusions:
Clouds
Feathers
Crystals or minerals
Knots
Cavities
Cleavage
Internal graining
Examples of Blemishes:
Polish lines
Scratches
Nicks
Pits
Chips
Breaks
Dark or light spots
While these features might not be found in every diamond, both natural and lab-grown stones can exhibit them. Each diamond is a one-of-a-kind beauty, often thriving with its unique inclusions and blemishes.
