IMO, half a mm is such a tiny difference you wouldn’t even know unless the stones were next to each other. The average credit card is .75mm thick as reference.

The larger you go, the less it will look like a diamond. Many people find that at 8mm/2ct, the difference starts to become particularly evident. So if your goal is to have it be mistaken for a diamond, it’s best to stay well below that. But, of course, most people don’t pay that much attention anyway.

Edit: Have you compared a diamond to a moissanite in person? It would be a good idea.

Half an mm won’t be noticeable, go for whichever stone smiles at you.

@lexip:  Go for the 8.5, especially if you have long fingers. It may seem large at first but you will very quickly acclimatise. 

For what it’s worth, it’s absolute bull that people can spot the difference between moissy and diamond on your hand regardless of size, especially if you’re going with a round or antique cut. People here used to say the telltale moissy sign was the “green tint” or the poor cut or the moodiness… since every single one of those issues have now been resolved with better quality moissanite these same folks now cling to straws and claim they can tell the difference but are “too polite” to call it. Please. ๐Ÿ™„

My husband could easily afford diamond versions of the moissanites I wear (we own a relatively large home in the center of a very expensive city, drive a luxury car, etc.) but I’m sure people would assume my gems are diamonds regardless because they literally can’t tell the difference (although I do brag about moissy to my friends haha). I posted a thread a few years back (with an old moissy type) proving this point. So go for the size you prefer and don’t worry about what people think!

@valintine:  Moissanites differ from diamonds in how they refract light, as you know. While some moissanite is now cut to minimize double refraction, most isn’t, and even the most well-cut moissanite doesn’t exactly replicate a diamond. The differences are evident in things like fire, lack of contrast/depth/sharpness, and ‘glassiness’ in sunlight. How prominent the differences are depends on the exact stone, but it’s misleading to suggest these things aren’t issues *for someone who wants it to be mistaken for a diamond*.  If someone loves their moissanite, that’s awesome! They can be beautiful. But the insistance that they look exactly like diamonds and no one can tell isn’t really accurate.

If you do like moissanites, August Vintage has nice ones.

@lexip:  If you want people to assume you have a diamond, you should buy a diamond: most people won’t pay attention, but the differences are perceptible. A lab diamond might be a good middle ground. Checking Rare Carat, an 8mm G/SI1/Ideal-cut lab diamond is ~3.5K, which given your context and from a cost per wear perspective is not unreasonable.

@lexip:  

I will say, there’s a bigger difference between moissanite and diamonds in person than in photos. Definitely compare side-by-side in person and out from the shine of LED lights. Even cover your hand over the stones if you need to. I initally thought I was going to buy a moissanite then after seeing them together realised I liked the dimond way more. Although round brilliants are much more similar. I would err on smaller if you want it to ‘pass’.

I also advise looking into lab diamonds if cost is the issue

@valintine:  agree with everything you said!! I’m from a long line of diamond dealers and this is absolutely true!  

OP, hey ๐Ÿ‘‹. Get the 8.5mm as it will be perfect on your long fingers!! It will be big but not over the top, although I don’t believe in that!! I could wear a 30 carat happily ๐Ÿคฉ. No one will ask you if it’s a diamond! Maybe family and friends. If you want to tell them what the stone is then that’s fine but completely up to you! Congratulations and welcome to the Bee ๐Ÿ˜Š.

This likely isn’t much help, but I have a 1 ct Moissanite and wear size 4.25. I think it looks plenty big on me – gorgeous and a little flashy (to me) but not to the point of me feeling like it’s gaudy or obvious. Mine also has a halo, so the ‘finger coverage’ is extra awesome. It’s bigger than I originally expected getting but I love it; I have no fear of ‘shrinkage’.

I compared it with 2 lab diamonds of the same size before choosing one at the jeweler. All three were stunning!

I have zero regrets; the price difference of doing Moissy instead of lab diamond meant we could buy the matching pave wedding band same day and stay within budget. I don’t know what may change as you size up in moissy, but I can’t imagine anyone EVER knowing my stone isn’t a diamond unless I told them. People have even done little social experiments where they ask people which ring is ‘fake’ and people have no clue.

@lexip:  Yeah, almost everyone in that thread was wrong but even more noticeable was that the most outspoken Bees who claim they can tell the difference didn’t even participate… because they couldn’t tell the difference and didn’t want to be publicly caught out. ๐Ÿคฃ That thread is old now so it’s not so apparent (Bees come & go) but it was really obvious at the time I made it that certain people were keeping quiet. And keep in mind, the moissy in those videos is the old crystal type, poor cut by C&C, and dirty haha, so it should have been super obvious to the keyboard sleuths. Absolutely tell your close friends and family if you want to, but equally don’t feel you need to: everyone will 100% believe you’re wearing a diamond unless you inform them otherwise. If you want to keep this info to yourself and quietly enjoy the thousands you saved and your sparkly gemstone, go for it!

@elisabetn:  You’re totally right, moissanite is a different material so its properties are different to diamond (and superior by most most measurements, such as durability and optical qualities), but those differences are not apparent to the naked eye when viewed on someone’s hand. The double refraction you mention, for instance, is literally impossible to detect in a round cut moissy without 10x magnification… so unless you have cyborg eyes you’re not ever gonna see that.
