Diamond Clarity Chart: Every Grade, and What VVS Buys

The diamond clarity chart runs eleven grades, from Flawless to I3. The scale is written at ten-times magnification; you wear the stone at one. That gap — between what a grader can find and what anyone will ever see — is where most clarity money is quietly spent. Below is the full chart, what each grade actually looks like on a hand, what the VVS premium buys, and the point past which the grade keeps climbing and the stone stops.

The diamond clarity chart, from FL to I3

The chart is the GIA's clarity scale — the trade's common language, and the scale IGI grades on too: eleven grades, six bands, judged at 10x magnification. HRD, the third lab whose paper crosses our bench, writes the same information in its own dialect — "Loupe Clean" where this chart says FL and IF, "Piqué" where it says I — and the bands translate closely enough that everything below applies to all three.

Grade	Band	Under 10x magnification	On the hand
FL	Flawless	Nothing, inside or out	Clean
IF	Internally Flawless	Surface marks only, nothing inside	Clean
VVS1, VVS2	Very, very slightly included	Inclusions a trained grader works to find	Clean
VS1, VS2	Very slightly included	Minor inclusions, found with effort	Clean in almost every stone
SI1, SI2	Slightly included	Noticeable under the loupe	Often clean — judge the stone, not the grade
I1, I2, I3	Included	Obvious	Frequently visible; can dull the stone

Read the right-hand column twice. Four of the six bands say some version of "clean". That is the entire economics of clarity in one column, and the rest of this guide is the working detail.

One note on the middle column: "works to find" is not a figure of speech. A VVS grade means a person whose full-time job is finding inclusions needed time to find them.

What diamond clarity actually grades

Diamond clarity is an inventory of what is inside the stone and on its surface. A diamond is grown — by the earth or by a machine — and growth is untidy. Things get caught in the crystal on the way up. The grader's job is to catalogue them: how many, how large, where they sit, and how easily they show at 10x. The clarity grade is the summary line of that inventory.

The things being counted have names:

• Crystals — specks of another mineral, or of diamond itself, trapped mid-growth
• Pinpoints — crystals too small to read as anything but a dot
• Clouds — clusters of pinpoints; individually invisible, collectively a haze
• Feathers — small internal fractures, named for how they catch the light
• Needles — thin rods of trapped material
• Blemishes — marks on the surface rather than inside: nicks, scratches, polish lines

Two facts stop most clarity anxiety. First, almost every diamond ever cut carries some of these; a grade is a description, not a defect notice. Second, position matters as much as size — a pinpoint under the table faces the world, while the same pinpoint near the girdle disappears under a prong. Two stones can share a grade and wear it very differently, which is why the report carries a map as well as a word.

Clarity is also not transparency. Milkiness and haze are a different problem — dense clouds or strong fluorescence can dull a stone at almost any grade — and a clean-graded diamond is not "clearer" to look through than one two grades down. It simply has less for a loupe to find.

How a lab actually decides the grade

The process is duller than the price differences it produces, which is rather the point. A stone arrives at the lab anonymous — no seller's name attached, so nobody grades a brand. It is weighed, measured, and passed to a grader who examines it at 10x, maps what they find, and writes a grade. Another grader repeats the exercise without seeing the first opinion. The grade on the report is the reconciled result, and on borderline stones more opinions are pulled in until the disagreement dies.

Two consequences are worth carrying into a purchase. First, a grade is an expert consensus, not a physical constant — instruments help find the inclusions, but weighing what they add up to is still judgement, which is why the same diamond can occasionally grade a notch apart at two labs. Second, the lab is paid to grade the stone, not to sell it, and that independence is the whole of the report's value.

Every band on the chart, translated to the hand

FL and IF. Nothing to find inside the stone — FL adds a clean surface as well. These grades exist because grading is thorough, not because wearing is. Between IF and VVS the difference lives entirely in the lab. Nothing changes on the hand.

VVS1 and VVS2. Inclusions so small that finding them at 10x is skilled work. On a finished piece of jewellery, at any distance your eyes can focus from, a VVS stone and a flawless one are the same stone.

VS1 and VS2. The working middle of the chart. Inclusions a grader finds without difficulty and a wearer essentially never does. The overwhelming share of stones in this band are eye-clean — the trade's term for "no inclusion visible to an unaided eye at normal viewing distance". This is the band where the paper and the look part company.

SI1 and SI2. The honest bargain, stone by stone. Under the loupe the inclusions are plain; on the hand, many SI stones — especially SI1 — are still eye-clean, and those particular stones are the best value on the whole chart. The grade alone cannot tell you which ones they are. Ask to see the specific stone, a video of it, or the plot on its report before deciding anything about an SI diamond.

I1 to I3. Included means what it says: inclusions frequently visible without magnification, and at the bottom of the band, enough of them to interfere with how light moves through the stone. A large feather in the wrong place can also make a stone more vulnerable at the setter's bench. There are sensible uses for I-grade stones — small side stones, tight budgets on pieces that will be worn hard and casually — but buy them with your eyes, never from a listing.

VVS1 vs VVS2: what separates them?

Where the inclusion can be seen from, not how much of it there is. A VVS1 stone's features are typically approachable only through the pavilion — the underside, below the girdle. A VVS2's can be picked up looking straight down through the table, still under magnification, still slowly.

That distinction is a grading-room fact with a price attached. VVS1 costs more than VVS2, and no wearer, owner or admirer has ever perceived the difference. If both are in front of you, let cut settle it: a sharply cut VVS2 outperforms a sleepy VVS1 in the only test that runs daily, which is somebody looking at your hand.

The report is where the sub-grade earns its keep. Plots differ stone to stone, and a VVS2 whose lone pinpoint sits under a facet junction, or wherever the setting will eventually cover, is functionally the higher grade without the higher invoice. That is an argument for reading the plot, not for trusting the letters.

Why does VVS cost more than VS?

Scarcity, and it is real scarcity. Crystals that clean are uncommon out of the ground, and a growth chamber cannot be instructed to produce one either — you take what forms. Every rung up the clarity ladder narrows the supply, and narrow supply carries a price. Nobody is inventing the premium.

What the premium does not carry is a visible improvement. Between a VS stone and a VVS stone of matched cut, colour and weight, the money buys a stronger document and an identical appearance.

Anyone quoting you a vvs clarity diamond price is also quoting carat, cut and colour in the same breath, and carat moves a bill hardest of all — which is why a single headline figure for "a VVS diamond" would be fiction. Ask for the four grades together or the quote means nothing.

Are VVS clarity diamonds worth it?

Sometimes, and the sometimes is specific. This is how we sort it at the counter:

• Worth it: step cuts. Emerald and Asscher stones have broad, unbroken facets and very little sparkle to distract the eye, so whatever is inside has fewer places to hide. On a large step cut, a high clarity grade earns its money.
• Worth it: large stones. Scale magnifies everything, inclusions included. A grade that vanishes at half a carat can announce itself at three, so the threshold worth paying for rises as the stone grows.
• Worth it: when the certificate is part of the gift. Some pieces are bought as much for the document as the diamond — an anniversary stone, something meant to be handed on with its paperwork. Buying the grade for its own sake is a legitimate reason to buy it.
• Not worth it: brilliant cuts around a carat or under. A well-chosen VS is already invisible-clean at that size, and the money released by dropping a band does visible work in the cut grade instead.

We also tell people the thing that occasionally ends a sale: a diamond is not an investment. Resale is usually well below purchase price, whatever the origin and whatever the clarity line says. Whatever the ring costs, the right reason to buy one is the hand it will sit on.

Where does the price stop following the eye?

The chart's own economics point one way: once inclusions stop being findable without a loupe — for most stones, somewhere around the VS band — you are paying for the certificate, not the look. Every grade above that line improves the document, not the ring.

The price ladder does not know this. Each step up the chart costs real money, because rarity is priced whether or not it is visible — a genuinely clean crystal is harder to grow and harder to mine, so the market charges for it. The market is not wrong to; the paper is real and the rarity is real. The question is whether you want to own rarity you cannot see.

Sometimes the answer is honestly yes — some buyers want the top of the chart for its own sake, and a certificate that reads VVS1 is a pleasure of a kind we understand. That money is not wasted if the paper is the point. But if the point is the stone on the hand, the arithmetic says: find the grade where your stone goes eye-clean, stop there, and move the savings to cut — the one property on the report your eye actually reads across a room. Our lab grown diamond price guide walks through how the four properties split a bill; clarity is rarely where the meaningful money belongs.

Clarity and colour, read together

A combined diamond clarity and color chart is really two scales sharing one budget — and clarity and colour are the two report lines buyers most often over-buy. The GIA colour scale runs from D to Z:

Range	Grades	What it means
Colourless	D–F	No tint a grader can detect
Near-colourless	G–J	Tint visible only against comparison stones
Faint	K–M	Warmth starts to show
Very light	N–R	Warmth an untrained eye begins to catch
Light	S–Z	Visible warmth

The two grades trade against each other in a useful way. In a white-gold or platinum setting, a colour tint tends to show before a VS-band inclusion ever will, so colour usually deserves the budget first. In yellow gold, the metal warms every stone anyway — a near-colourless grade disappears into the setting, and the budget can move back toward clarity or carat. Balancing the two against a fixed budget is most of what a good quote is.

GH SI: four grades sold under one label

A GH SI diamond is not one grade. It is four.

G and H are two colour grades. SI1 and SI2 are two clarity grades. So "GH SI" describes any of four combinations, and the distance from the best of them to the worst is three steps on the scale. A seller quoting the label is quoting the parcel. Somebody still has to decide which stone comes out of it.

No laboratory grades a stone "GH". A G sits at the top of the near-colourless band, an H one step below it. Unmounted, side by side, on white paper, a grader tells them apart. Set in a ring on a hand, effectively nobody does.

Why so many Indian jewellers quote the band

Because the trade genuinely buys in ranges, and the range is what they can honestly tell you.

Small stones do not arrive at a workshop one at a time with individual reports. They arrive as parcels, sorted to a band. The laboratories sort that way too: GIA's own melee analysis service groups small stones into colour ranges — D-to-F, G-to-H, I-to-J, K-to-Z — and returns the parcel described by its band, not stone by stone. "GH" is not a marketing invention. It is what the paperwork on a parcel actually says.

GH SI is one of a handful of bands the Indian trade buys by default, alongside GH VS and IJ SI. A retailer quoting you a GH SI diamond is quoting the parcel spec, and quoting it accurately.

The gap opens one step later. A G SI1 and an H SI2 both sit inside that parcel and both are correctly described as GH SI. They are not the same stone, and whoever picks between them is making a decision about your piece that you never saw. That is the whole reason two quotes on identical paper come back at different numbers.

Which of the four you actually want

Inside the label	What it is	Our read
G SI1	Best of the box	The one to ask for by name.
H SI1	One colour step down	Usually the buy. The step you gave up is the invisible one.
G SI2	One clarity step down	The gamble. Check this stone before you commit to it.
H SI2	Bottom of the box	Fine in small stones and busy settings. Verify it in anything large or step-cut.

Now the part worth taking away. Between an H SI1 and a G SI2 — same label, same band, often the same quoted price — take the H SI1 every time.

The reasoning is that the two axes are not symmetrical. Dropping one colour grade, G to H, moves a stone one step inside a band that is already called near colourless, and that step disappears the moment the stone is on a hand. Dropping one clarity grade, SI1 to SI2, moves toward the point where an inclusion becomes something you can see without help. One of those steps is invisible and the other one might not be. Give up the invisible one.

That is also the single most useful question you can put to a seller quoting the range: not "is it GH SI", but "is it the SI1 or the SI2".

A pair is a harder problem than a stone

If you are buying earrings rather than a ring, the range works against you twice over.

Two stones both sold as GH SI can be a G and an H, mounted two inches apart on the same face. That is where a single colour grade stops being theoretical. One stone has nothing to be compared against. A pair compares itself, permanently, for as long as it is worn.

So for earrings, ask for the pair to be matched: same letter, same clarity grade, measurements close enough that the two face up alike. Expect it to narrow the choice and take longer. It is the one place we push people to tighten a spec rather than relax it. How that shows up in a quote is covered in what sets a diamond earrings price.

Does the clarity chart work for lab grown diamonds?

Yes — the same chart, the same 10x loupe. A lab grown diamond grows the way any crystal grows, only faster and under supervision, and growth leaves the same fingerprints: trapped crystals, pinpoints, feathers, the occasional cloud. Lab grown does not mean flawless.

What origin changes is the bill. The same specification — the same clarity band included — runs up to 60% less lab grown than mined; the production line is simply cheaper than the geology. So the chart works twice as hard for you on a lab grown stone: the eye-clean logic above still finds the sensible grade, and the economics mean that grade costs less to begin with. A lab grown VVS stone reaches buyers for whom mined VVS was never a real option, and climbing to the grade stops being a display of budget and becomes a straightforward question of what you want. Our lab grown diamond rings page shows what that does to a finished piece, with the certificate in the box.

Which laboratory still grades this spec in 2026

This is the part that changed recently, and most pages on the subject have not caught up.

If your stone is natural, nothing has changed. GIA, IGI and HRD all still grade it on the letters and numbers this page describes.

If it is lab grown, the ground moved twice. GIA stopped grading lab grown diamonds on the four Cs in October 2025 and now classifies them Premium or Standard — and because Standard requires VS clarity, an SI lab grown stone does not qualify for a GIA assessment at all. Then HRD stopped issuing quality certificates for loose lab grown stones as of 2026, keeping only mounted jewellery.

Which leaves one. For a loose lab grown diamond at GH SI, IGI is the lab that will still put the letters on paper. That is not a recommendation, it is arithmetic — and it is worth knowing before a seller tells you their lab grown stone is "GIA quality" without showing you a report.

How do you check the clarity grade on the certificate?

Never from the listing — from the report, and then from the lab that wrote it. Three steps:

1. Get the report number. Any seller of a certified stone can hand it over. Hesitation on this question is an answer in itself.
2. Look it up at the source. IGI's report lookup returns the lab's own record; GIA and HRD run the same service. If the record and the printout disagree, trust the record. There is a full walkthrough of the lookup if you want every step and the edge cases.
3. Read the plot, not just the grade. Most full reports carry a clarity plot — a small line drawing of the stone with symbols marking each inclusion's type and position. It is the inventory behind the summary line.

The plot rewards a minute of attention. It tells you where the inclusions live — under the table, or out at the edge where a prong will sit — which the grade alone never says. And because no two stones carry the same inclusions in the same places, the plot is a fingerprint: it is how you confirm the stone in front of you is the stone on the paper, years later or across a counter today.

The plot matters most exactly where the money question is hardest: the SI band. Two SI1 stones can carry the same grade because one has a single crystal hidden at the girdle and the other has a feather sitting under the table. The first is a bargain; the second is why the band has a reputation. The plot tells you which one you are being quoted.

Which clarity should you actually buy?

Work the order of operations, not the chart. Cut first — it decides whether the stone looks alive, and no clarity grade rescues a dull cut. Then find where eye-clean starts for your stone, which moves with three things:

• Size. Inclusions are easier to see in a bigger stone. What hides in a quarter-carat stud can show in a two-carat centre stone, so the sensible clarity band climbs with carat weight.
• Shape. Step cuts — emerald, Asscher — are open windows with long clean facets, and they hide the least; they deserve a higher clarity band. Brilliant cuts scatter light over dozens of small facets and forgive far more.
• Distance. Nobody inspects earrings at reading distance. Studs and pendants live at conversation range, and the clarity band that is honest there is not an expensive one — a large part of why sensible earrings cost so much less than centre-stone rings. The diamond earrings price guide does that budget maths separately.

As rough starting points — the stone always gets the final vote:

Stone	Where eye-clean usually starts
Brilliant cuts around a carat or under	SI1, judged stone by stone
Brilliant cuts well above a carat	VS2 and up
Step cuts (emerald, Asscher), any size	VS2 and up, often VS1 for large stones
Small side stones and pavé	SI is routinely fine

The setting votes too. A prong sits exactly where many edge inclusions live, a bezel wraps the entire girdle, and a halo keeps every neighbouring eye busy — all three can turn a borderline stone into an easy yes. This is the kind of judgement a listing cannot make for you, and the reason we would rather be sent a report number than a budget alone.

And the advice that costs us the occasional sale: if the choice is a flawless grade or a better-cut VS at the same money, take the VS. You will see the cut every day and the flawless grade never. Good diamond clarity, for a stone that will be worn rather than filed, means the least expensive grade at which your stone is eye-clean — found by looking at the stone, not the letter.

The questions everyone asks

What is the best diamond clarity?

FL is the top of the chart, and almost nobody should buy it. The best diamond clarity for a worn stone is the lowest grade at which that particular stone is eye-clean — usually in the VS band, sometimes SI. The chart ranks the paperwork; your eye ranks the stone.

Is VVS clarity good?

Yes, and by a comfortable margin — it is the third band from the top, beneath only Internally Flawless and Flawless, and every stone in it is eye-clean. The sharper question is whether the money is buying anything you can see, and on a typical brilliant cut it is not.

Can you tell a VVS diamond from a VS diamond by eye?

Almost never. Both read clean at any normal viewing distance, and the difference lives inside the loupe. The exception is the one worth knowing: in a large step cut, a VS inclusion can occasionally surface to the naked eye, which is exactly where paying up for VVS makes sense.

Which is better for an engagement ring, VVS1 or VVS2?

VVS2, for most budgets. The saving is real, the visual difference is not, and the money does more in the cut grade or the carat weight. Go to VVS1 only if the certificate itself is part of what you are giving.

Is SI clarity good for an engagement ring?

Often, and always stone-by-stone. Many SI1 stones are eye-clean, and an eye-clean SI1 is the strongest value on the chart. Ask for the clarity plot or a video of the actual stone rather than deciding from the grade alone.

What does GH SI mean in diamonds?

It means the stone is either G or H in colour and either SI1 or SI2 in clarity — a range covering four combinations, not a single grade. A report on an individual stone will never print "GH SI"; that phrasing belongs on parcel paperwork.

Which is better, VS1 or VS2?

VS1, by one notch of work under the loupe — its inclusions are slightly harder to find at 10x. On the hand the two are not distinguishable. Choose between the two actual stones on cut, not between the two labels.

Can you see diamond inclusions with the naked eye?

Above the SI band, essentially never — that is what those grades mean. In SI stones, sometimes; in I-grade stones, usually. Size and shape move the line, which is why a grade that is invisible in a stud can show in a large emerald cut.

Do lab grown diamonds have inclusions?

Yes. Growth traps things whether it happens underground or in a reactor, so lab grown stones carry crystals, pinpoints and feathers like any others — IGI grades them on exactly this scale. Controlled growth improves the odds of a clean stone; it does not guarantee one.

Does clarity affect a diamond's sparkle?

Far less than cut does. Grade-to-grade differences in the eye-clean bands change nothing you can see; heavy clouding at the bottom of the chart can genuinely dull a stone. If sparkle is the goal, spend on cut and stop climbing the clarity chart at eye-clean.

Is clarity or colour more important?

Neither outranks the other everywhere — the setting decides. In white metal, a colour tint usually shows before a VS-band inclusion, so colour deserves the budget first. In yellow gold, the metal warms the stone regardless and clarity moves up the list. Cut outranks both in every metal.

Why do song lyrics mention VVS diamonds?

Because the grade turned into shorthand for the expensive end of the scale, and it scans well. The scale being referenced is the real one, and any particular piece either has the report to back the claim or does not.

The chart is a map — bring it a stone

A clarity grade records what one grader found at ten-times magnification on one particular day. It cannot tell you whether the stone looks alive on a hand, and it was never meant to. Use the chart to stop overpaying; use your eyes, or ours, to choose the stone.
