A diamond can be flawless on paper and still disappear in a weak setting. It can also carry a few tiny natural birthmarks and look completely clean once it is set in a pendant, ring, or iced-out piece. That is why diamond clarity grades explained should never be a lecture in alphabet soup. It should help you choose a stone that hits hard in real life, not just under a loupe.
Clarity measures a diamond’s internal characteristics, called inclusions, and surface characteristics, called blemishes. These marks formed while the diamond was growing deep within the earth, or during its cutting journey. Most are invisible without magnification. The move is knowing when they matter, when they do not, and where your money will show more.
Diamond Clarity Grades Explained: The Scale
The diamond clarity scale runs from Flawless down to Included. A trained grader typically evaluates a loose diamond at 10x magnification, looking at the size, number, position, nature, and visibility of its characteristics. That last part matters: two diamonds with the same clarity grade can look very different face-up.
FL and IF: Flawless and Internally Flawless
FL means Flawless. No inclusions or blemishes are visible to a skilled grader at 10x magnification. IF means Internally Flawless. The diamond has no visible internal inclusions at 10x, though it may have minor surface blemishes.
These are rare, elite grades. They carry serious bragging rights and can make sense for collectors, investment-minded buyers, or anyone building a true one-of-one heirloom. But for most custom jewelry, the price jump is substantial while the visible difference from a high-quality VVS stone is usually impossible to spot with the naked eye. You are paying for rarity, not a dramatically different sparkle.
VVS1 and VVS2: Very, Very Slightly Included
VVS diamonds have minute inclusions that are extremely difficult for a grader to see at 10x magnification. VVS1 is generally cleaner than VVS2, but both sit in premium territory.
If you want a diamond with exceptional purity for a high-visibility engagement ring, a close-up pendant, or a luxury custom design, VVS delivers a clean, elevated look. It is also a popular choice when the story behind the piece matters as much as the visual impact. The trade-off is simple: VVS is beautiful, but a well-selected VS diamond may look identical once set and leave more room in the budget for size, cut, or a more ambitious design.
VS1 and VS2: Very Slightly Included
VS clarity diamonds have minor inclusions that are difficult to see under 10x magnification and are often eye-clean. For many buyers, this is the sweet spot between premium quality and smart spending.
A VS1 or VS2 diamond can look crisp, bright, and high-end in an engagement ring, tennis bracelet, custom chain, or diamond pendant. At Johnny’s Ice & Co, this is often the lane for clients who want their money working across the whole piece: better diamond coverage, stronger design details, a heavier gold build, or a custom setting that separates their jewelry from the usual catalog look.
Still, do not buy VS blindly. A VS2 with a dark inclusion directly under the table, the large flat top of the diamond, may be more noticeable than another VS2 with a tiny inclusion tucked near the edge. Always judge the actual stone, not the letters alone.
SI1 and SI2: Slightly Included
SI diamonds have noticeable inclusions at 10x magnification. Many SI1 diamonds are eye-clean, especially in smaller sizes or in designs where stones are set close together. SI2 diamonds can also offer value, but they require a more careful inspection.
For pavé work, diamond-encrusted pendants, cluster earrings, and other designs with many smaller stones, SI clarity can be a strong choice. Individual inclusions are less likely to stand out, and the overall effect is still all shine. In a large center stone, however, clarity becomes more personal. An SI diamond may look perfectly clean from normal viewing distance, or it may show a visible mark depending on the inclusion type and location.
The goal is not to avoid SI automatically. The goal is to make sure you are getting an eye-clean diamond for the way you will actually wear it.
I1, I2, and I3: Included
Included diamonds have inclusions that are obvious under 10x magnification and may be visible without it. The inclusions can also affect transparency, sparkle, and, in some cases, durability.
These grades can make sense for certain budget-driven projects, especially when using small accent diamonds in a design where no individual stone is the main event. But with a larger diamond, an I-grade stone can look cloudy, show dark spots, or lose the sharp fire that makes diamonds feel alive. A lower price is only a win if the piece still looks right when the lights hit it.
What Actually Matters Beyond the Grade
Clarity is only one part of the diamond story. Cut has the biggest impact on how much a diamond sparkles. A beautifully cut VS2 can throw more fire and life than a poorly cut VVS stone. Color, carat weight, shape, setting style, and the diamond’s overall transparency also change the final look.
Inclusions are not all created equal. A tiny white crystal near the edge may disappear once the diamond is set. A black crystal under the table can draw the eye. Feathers, which are small internal fractures, need a closer look if they reach the surface or sit in a vulnerable area. Clouds can reduce brilliance if they are dense enough, even when no single inclusion seems dramatic.
Placement changes everything. Inclusions near the outer edge can often be hidden by prongs or a bezel. Inclusions in the center are harder to disguise. Shape matters too. Step-cut shapes like emerald and Asscher cuts have broad, open facets that can reveal inclusions more easily. Round brilliants, with their busy faceting and intense sparkle, are generally more forgiving.
The Best Clarity Grade for Your Jewelry
There is no universal best clarity grade. There is only the best grade for the look, budget, and purpose of your piece.
For a diamond engagement ring with a larger center stone, VS1 through SI1 is often the practical range, depending on the stone and shape. Choose eye-clean first, then decide whether the extra purity of VVS fits your priorities. For stud earrings, tennis jewelry, and pavé-heavy custom work, SI and VS stones can deliver major visual impact because the design reads as one field of light.
For a statement pendant or custom charm, diamond size and setting style matter more than chasing a top clarity label. If the design features a single large centerpiece, inspect clarity more carefully. If it is flooded with smaller stones, balanced matching and strong setting work can matter more than whether every diamond is VVS.
For grillz, clarity is part of the conversation, but craftsmanship is the foundation. A clean diamond layout will not save a piece that fits poorly or lacks secure, precise stone setting. Custom work should be built around your mold, your bite, and the way you want the piece to flash when you talk, laugh, and step out.
Natural and Lab-Grown Diamonds Use the Same Clarity Scale
Natural and lab-grown diamonds are graded using the same clarity language. A lab-grown VVS diamond and a natural VVS diamond can both have very high clarity. The difference is origin, not the meaning of the grade.
Lab-grown diamonds can allow buyers to prioritize larger size, higher color, or higher clarity within the same budget. Natural diamonds bring geological rarity and a distinct origin story. Neither choice is automatically better. It depends on whether your priority is size and specs, rarity, long-term symbolism, or a combination of all three.
Buy What Looks Clean, Not Just What Sounds Expensive
A clarity grade is a tool, not a flex by itself. Ask to see the diamond face-up, not only magnified. Look for transparency, brightness, and any inclusion that pulls your eye at a normal viewing distance. If a stone looks clean and lively in the setting you want, it may be the smarter buy than a technically cleaner stone with a price tag that limits the rest of your vision.
The strongest jewelry choices are intentional. Put the budget where it will be seen: a diamond that sparkles, a setting that protects it, and a design that makes the piece unmistakably yours.
