I believe mine is a VS2.  I haven’t looked at it with a loupe so I haven’t seen any inclusions.  The color on mine is an H; I’m pretty color sensitive and can sometimes pick up some yellow in it, but in the office it looks extremely white.

I think if I would do it over again I would get an eye-clean SI1 or SI2 and a slightly bigger stone.  I feel like mine is plenty big (.72 ct) but a 1 ct would have been nice.  My ring size is 5.75 for reference.

To be honest, I would get the best cut stone you can; an ideally cut stone will look bigger than a larger carat weight but not-as-ideally cut.

Between color and clarity, it depends on how color sensitive you are.  There *are* some lighting situations where I can definitely see yellow in my stone, but that’s just me.  I think you could safely drop down to “I” and be OK.

ETA: In the paragraph above, I mean “I” for color, not clarity.

@Anise:  How big is your stone? What shape? I have an Old European cut and so it’s very irregular (not perfectly round). It’s estimated at si2 but I’m pretty sure it’s a I1. I can see a little speck if I look super hard.. but it’s also only .40 ct so you really can’t notice, and it’s super sparkly. I would look at any stone you buy. You can find SI1 with visiblel inclusions and ones that are eye-clean. 
ETA: Oops, sorry, that was supposed to be directed a tOP.

@NoOneYouExpect:  I wouldn’t personally go below VS2 unless I could take a good look at the SI1 and make sure it was eye clean by my own definition.

Often eye clean is a subjective term, and it’s typically defined by looking at the diamond only from the top.

I was at a jeweler’s and saw a loose SI1… with a huge black carbon spot in the middle. It wasn’t obvious from the top, but it was from the side. I suppose if it was carefully mounted, you could hide it… but I wouldn’t have known this if I bought it online, for example.

I am also a fairly clumsy person and I would worry that if I smacked my diamond on something, it would shatter (this happens). The more inclusions, the weaker it is. I would never get an “I” stone for that reason. I am also a bit of a purist… I like the idea of having a fairly flawless stone. You don’t need to go to the VVS range necessarily, since you’re paying a premium… but the SI range can be risky. Also, the more flawed the stone, the less sparkly it is – even if it’s well cut.

I think you’d probably be fine with SI1 or possibly SI2, just make sure you can look in person.

What color are you thinking of going up to? If you had something like SI1 H color, you’d have a pretty nice looking stone (given that it’s well cut), but I would want to see it in person first. Also, depending on what shape the diamond is also impacts how low you want to go on clarity. Round stones hide flaws the best, but if you went with a step cut like emerald or asscher, you’d want to get a fairly high clarity since flaws are much more apparent.

@NoOneYouExpect:  I have an SI1 pear shaped diamond, with excellent cut, excellent symetry, E color, and no obvious bow tie effect…..I have not noticed any visible inclusions, it all depends on where they are located…..when I was looking at rings….i was suprised that a lot of “chain” stores,like zales,kays, riddles, and many others have gorgeous…I1 and lower clarity diamonds, most that i seen were I1 and k color and lower….and looked very pretty…..i think it depends on where the inclusion is located in relation to prongs, and the size and cut of the stones…

its defenitly one that you need to see a few examples of…..

@love108:  Mine is a modern round, .72 ct.

It also depends on the cut itself. I have an emerald cut diamond and clarity matters for sure and it’s obvious when it aint so great. That was my priority, as well as it being at least 1 carat.

I have a round SI1 and I don’t see any inclusions. I would definitely get the same clarity again. From your 2nd post on this thread it sounds like you had similar thinking to what I did – we went for excellent cut, and then I maxed out carat while lowering clarity and colour to the lowest I was willing to go (SI1 and I, with strong blue fluorescence as it may negate some of the warmth). I don’t see any inclusions and it looks white to me. It’s a 0.6 carat though, so you might take more caution with a much larger stone.

@Anise:  What is the price difference between VS2 and SI1? If you dont’ want to budge on color and you’re trying to lower costs, I would go with the SI1 before going down in color or clarity if they’re more important. But look at it first! 🙂

Go with the SI1!  I have an SI1 and cannot see a single inclusion!  Highly recommend the SI1

my center stone is SI1 and i don’t see any inclusions. it’s .5ct. i think the larger stones will show the inclusions but with the smaller ones, it’s really hard to see anything. i would probably go with the same stone again since you can’t see any inclusions. i have a 3 stone (all rounds) and the quality of 2 side stones came included with the setting. they’re VS1 or 2 (can’t remember) and you can’t tell the difference between them and the center stone (same with the color. they aren’t the same as the center but you can’t tell).

@love108:  SI1 *is* clarity.  You’re just as capable of looking up price differences on Pricescope or Blue Nile as I am.  🙂

We just purchased the diamond for my engagement ring, my brother-in-law is a jeweller so he had his diamond dealer help us select a diamond that I loved in our budget.  I ended up getting an I1 1.2 carat round stone, very good cut, with D colour.  He showed us stones that were SI1 with H-J colour and when compared to the I1 you could tell that the stone had a yellow colouring to it.  The diamond dealer showed us the inclusion that was on the bottom of the stone and placed it in a setting to show that once set it’s not even visible.  His advice was go with the best colour because it makes the biggest difference to the stone and my brother-in-law said so as well.  My diamond is colourless and looks amazing.
