Hello guys,

I'm new to this forum! Recently saw a reasonably priced lab diamond
0.73 G VS1
It looks super clean, however there's this blue nuance comment under the IGI cert.
Is blue nuance good or bad? I have no clue please do advice thank you!

Interesting. There is speculation that the blue tone can help it look more white. I don’t think anyone on this board besides trade have seen one in person. If you are serious it’s worth taking a look in person since JA has a return policy.

One of the MMD trade vendors on here specifically excludes it from their listings because they don't like it and state that their customers don't like it (IIRC).

I think it's quite cool - who wouldn't want a blue diamond? :D lol

If you like a blue nuance stone and don't really care what others think, and aren't intending on selling it later on, why not get what you like? :)

Thanks for the comments guys!
I've did a research and it seems like the blue nuance is caused by boron nitrate or something during the HPHT process. Isn't boron nitrate like harmful to humans though?

Will probably get it if it's not harmful. Not sure if they do accept returns from Singapore though.


EDIT: Nvm it's sold lol

The boron would be incorporated into the diamond crystal structure. It’s not something that’s going to leach out and harm you. Even if it did, boron is not particularly toxic to humans. It’s used in all sorts of household things like detergent.

Not an expert but I think it's highly unlikely a diamond will be shedding any atoms of boron or anything else - it's one of the hardest substances we know! :))

I have a 2 carat with blue nuance that I specifically sought out because I actually like it. It appears anywhere from bright white to steely gray to light blue depending on lighting. It is IGI graded as a J VS2 ideal cut. I know some people don't prefer them though. I like lower color range stones and fancy colors, and this just worked for me. Basically, instead of a yellow/brown undertone that most diamonds (natural mined or lab) have, this stone will have a blue body color. In nature, this does happen, but it is extremely rare. It is common with lab stones grown using the hpht method however. I attached a bunch of photos in different lighting for you. It appears that quite a few posts ask about blue nuance, but I have not actually seen any stones posted that have it. Hope this helps you make a decision! 1- indirect outdoor lighting 2- evening outdoor lighting 3- mid day direct sunlight 4- indoor lighting

@AllthatglittersIsntgold thank you for posting your beautiful stone!! I have to say, when I read what blue nuance is, I wondered why anyone would find it a characteristic to avoid -- I think it looks really lovely and gives another dimension to a white stone. Perhaps some people think it gives away the diamond as "lab grown", but I don't intend to be shy or sneaky about my lab grown diamonds, I plan to enjoy them as is. I'm knee deep in projects that need finishing and my diamond budget is shot, but I'm really thinking I'll be looking for a blue nuance lab-grown in the future...!!

Thank you :) as you can see in the pictures, in "normal" lighting situations (like inside a home or store or outside on a relatively sunny day) you can't really see any blue or gray. I've been told the dark gray appearance is moreso an optical illusion with a very well cut stone and that earth mined diamonds that are exceptionally cut will likewise appear dark in certain conditions. It looks like a colorless diamond-- way higher in color than a J stone. I've never had anyone comment on anything but its size. I personally find it interesting and makes it stand out. I hope posting photos will help others who see it listed on their grading reports! It's definitely worth picking one up at some point for a fun piece if you can!

Oh, so, look at this! I'm not able to see any certs because it's JA, so can't be sure that these are "blue nuance" diamonds, but I think I'm right: look at the difference in the profile colors, and a corresponding trend in pricing! Hard to tell face-up but from the side there are clearly "yellow-tone" versus grey-tone (which probably look blue in some lighting situations). Personally, I'd 100% take the very substantial "blue nuance" discount. ;-) Reminds me of strong/very strong fluorescence in that way (which I am also a total fan of, but results in a slight discount though perhaps not as much as historically!).

Bingo! You nailed it. Face up, you honestly will have a hard time telling most of the time after it's mounted. Face down and profile view loose, you can absolutely see it clearly, especially when pictured next to a yellow undertoned stone. It's the difference between white printer paper and super bright white printer paper or a soft white lightbulb vs a daylight bulb.
I also love fluorescence! It's truly a preference thing.
I've seen some comments here on PS diss blue nuance in stones and call them awful and defective, but I honestly think it's a preference and nothing there's inherently bad about it- it's just a property of the stone. All gemstones have properties that affect preference. I don't see why blue nuance would be any different.
