VS1 and VS2 sit side by side on the clarity scale and share one label: very slightly included. The question that matters is whether anyone will ever see the difference once the diamond is on a hand. We answer it with real stones from our certified loose diamonds in Beirut, each graded by an independent laboratory (see our GIA-certified diamonds) and filmed in 360°, so you can judge the two grades on actual diamonds rather than on a chart.
What the two grades mean
Clarity grades the tiny natural features inside a diamond, called inclusions, and on its surface, called blemishes. A trained grader judges them under 10× magnification, weighing their size, number, position, type and how much they stand out. GIA and HRD both use the VS1 and VS2 grades, and in both systems the difference is how easily the grader finds the inclusions, not whether you can.
| VS1 | VS2 | |
|---|---|---|
| Full name | Very slightly included, first grade | Very slightly included, second grade |
| At 10× | Minor inclusions, found with effort | Minor inclusions, a little easier to find |
| Typical features | A small crystal, feather or cloud | The same features, slightly larger or more central |
| To the naked eye | Clean in virtually every shape | Clean in almost every brilliant shape; check step cuts |
| Where it pays | Step cuts, stones above about 1.5 carats | Round, oval, cushion and most brilliant shapes |
The grade is a summary. The plot on a full GIA report, the map of inclusions, tells you what they are and where they sit, and our guide on how to read a GIA report shows where to find it. Our colour and clarity chart places both grades on the full scale from Flawless to I3.

Here is one stone of each grade from our Beirut stock with its 360° video and full grades; the two may differ in size or colour, so watch the inclusions as each stone turns.
When to choose VS1
VS1 earns its place when the shape or the size gives inclusions fewer places to hide.
- Step cuts. Emerald and asscher cuts have long, open facets that let you look straight into the stone. A VS1 gives you a margin that a brilliant does not need.
- Large stones. Above about 1.5 carats the table is wider and each inclusion physically larger, so the extra grade buys reassurance.
- Your own peace of mind. Some buyers want inclusions that are hard to find even under a loupe. That is a fair reason, as long as you know the loupe is the only place the difference shows.
When to choose VS2
For most engagement-ring diamonds, VS2 is where we would stop. In a round, oval, cushion, radiant or princess cut up to about 1.5 carats, a VS2 faces up as clean as a VS1 to the naked eye, and the step down in grade frees budget for the things people do see: a better cut, a whiter colour or a little more size.
Still watch the video. A VS2 with a few white pinpoints near the edge is a better stone than one with a single dark crystal under the table, even though the report gives them the same letter. And if you are tempted to go one step lower, our comparison of VS2 and SI1 clarity explains where eye-clean stops being a given.
How shape, size and setting change the answer
Shape
Brilliant cuts such as round, oval, cushion, radiant and princess break light into many small flashes, which disguises small inclusions. Step cuts do the reverse. For an emerald cut, lean towards VS1; for a round brilliant, VS2 is ample.
Size
Under about one carat, the two grades are interchangeable to the eye. Above 1.5 carats, a VS2 inclusion is larger in absolute terms and sits under a wider table, so look closely at the video or move up to VS1.
Setting
Prongs can sit over an inclusion near the edge, and a bezel covers the rim of the stone altogether. A halo draws the eye outward, away from the centre. None of this changes the grade, but all of it changes what is visible, which is why position matters more than the letter, as our guide to eye-clean diamonds explains.
How we would choose
Buy VS2 for a brilliant shape and put the difference where it shows; buy VS1 for a step cut or a large stone. Either way, judge the actual diamond, not the letter. Send us the shape and size you have in mind on WhatsApp and we will send the certificate and 360° video of each stone that fits.
Common questions
Is a VS2 diamond eye-clean?
In round and other brilliant shapes, almost always. VS2 inclusions are minor and need 10× magnification to find. The exceptions are step cuts, stones above about 1.5 carats and the occasional dark crystal right under the table, which is why the 360° video of the actual stone is worth watching before you choose.
Is VS1 clarity worth it for an engagement ring?
For an emerald or asscher cut, or a stone above about 1.5 carats, yes. For a round, oval or cushion of ordinary size, VS1 buys a difference only a loupe confirms, and the same budget usually does more for the ring as a better cut or a slightly larger stone.
Does a VS1 diamond sparkle more than a VS2?
No. At these grades the inclusions are too small to block light in any way you would notice. Sparkle comes from the cut. A well-cut VS2 will outshine a poorly cut VS1, so compare the cut, polish and symmetry grades before you compare clarity.
Do GIA and HRD grade VS1 and VS2 the same way?
Both laboratories use the same VS1 and VS2 grades, judged at 10× magnification, and both are independent of the seller. Whichever laboratory graded the stone, check the report number on the laboratory’s own website and make sure the grades match the listing before you pay.
Is a VS1 diamond more durable than a VS2?
No. At the VS level, clarity makes no practical difference to durability in everyday wear. What matters for strength is the kind and position of an inclusion, such as a feather reaching the surface near the girdle, and that is a question about the individual stone rather than its grade.
