Hi there! My boyfriend just recently told me about the diamond he bought and was excited that it had a strong blue fluorescence. I think he thinks it’s cool (he is a scientist) so he seems pretty excited about this aspect. I’d never really heard about fluorescence in diamonds so I am new to this too.
As for me, I really dislike the idea of a glowing blue diamond. I am hoping some of you will be able to help me better understand what this will look like. It is an I color 1.0 carat with Strong Blue fluorescence. Does anyone else have a stone like this? Will it show up in the daylight? Make it cloudy? How often does it really show? I’ve heard mixed things that sometimes it shows in settings like a dimly lit restaurant to the outdoors to not at all and I am really confused. I am super nervous but hopeful that it is not what I am imagining in my head – I have never seen one IRL.

I also love fluor haha. It’s so cool!
Very very very very few diamonds with strong fluor have negative side effects. They *can* appear milky, but the vast majority dont.
It will only show up under UV light. So a bight sunny day you may notice a slight blue tinge, however most diamonds will also reflect colours it sees as well – ie a blue sky. So it may not appear that much different.
It is highly unlikely anything would show in a dimly lit restaurant. Fluor is actived by UV light. There wouldn’t likely be any UV light in a dark restaurant.
The benefit of this though, is that an I will have some yellow tint. The blue will counteract that, and make the stone look brighter and whiter. I’ll grab some pics for you 🙂 Make sure to buy a UV light off amazon so you can test it out and see for yourself!
eta – I put some pics below. IMO the blue will be seen pretty rarely for the most part. How often are you going to be out in direct sun staring and criticizing your ring? If you work an office job, you’re more likely to see it inside while typing and whatnot (like I am now lol). Unless you are a hardcore raver or go glow-in-the-dark bowling alot, you will very rarely see it under full UV light (hence why I say to get a light so you can see it!). Also, consider that to make this VSB in your diamond that there had to be the exact right mix of chemicals (normally boron) situated right next to the carbon and over millions of years it was compressed together to create your unique diamond. That’s one of my favourite things about fluor!

Aside from the typical “the higher the florescence the more it glows under UV light”, diamonds with higher levels of florescence are more likely to have a blue-ish hue in direct sunlight (not to be confused with the blue color reflecting from the sky). Stones with higher levels of florescence really need to be evaluated on a case by case basis as they can sometimes (most say rarely) make a diamond appear hazy/less clear, which is why they are usually discounted vs. diamonds with lower levels of florescence. But the only way to know is to see the diamond in various lighting conditions to see if the higher level of florescence are detrimental. GL

Here is a J VSB, indoors and then outdoors in direct sun
Here is another J SB, indoors, outdoors, and under a UV light
Here is an I VSB, so very similar to what you will have

Many, many years ago fluorescence used to be sought after and then someone decided it was bad. My mom’s engagement ring is an antique cut with strong blue flourescence and it’s a beautiful diamond. Walt until you get the ring and then decide for yourself.

This is I colour with very strong fluorescent. Sparkles nicely. Has a blue-ish touch to it in very strong and direct sunlight. Normally it just appears whiter in sunlight. I think it’s cool – but I like “imperfections”

Thank you!! This has made me feel much better. After looking into it, it seems like especially with the I color it will be perfect. My fear was that it would glow in the dark, but it seems like that is just a ridiculous thought to have even had.

I actually desire blue fluorescence in a stone. First of all, it improves colour… and second of all it’s like a hidden super-power. I also like that I’d be able to always know right away that it was my stone, and not actually swapped out by a jeweller by a quick flash of a UV light. I dunno, I think it’s really neat and beautiful.

PP’s have you covered on this one! I think you’ll absolutely love it and eventually forget it even has it. My F color diamond has medium blue fluorescence making it resemble an E color diamond!

I’ve heard sone advise against getting a colorless diamond that has a strong blue florescence for fear that it will be milky or dull in direct sunlight. In my experience that couldn’t be farther from the truth at least with my specific diamond. I have a E color with the strong blue fluorescence and no matter the lighting it’s sparkles like crazy. The icy blue hue that it gives off sometimes is actually what attracted me to the stone I think it’s so gorgeous here are some pics below where you can kind of see the variation in color.

That is so very sweet! I love that he is emotionally invested in his own personal way 🙂
As others have mentioned, I wouldn’t worry about it at all. And here’s a little fact list from the GIA:

Hi! This is my diamond outside. I color VSB.
this one is indoors next to my sister’s D colored.

I love fluorescence! To me, the effects aren’t as drastic as you may envision but it has a brightening effect that I just don’t see in my non-fluro stones. This is my I color with strong fluorescence outdoors, where the UV is the strongest.
