So our last diamond sold, so we are quickly picking a new one. we are between a .31 and a .46 with all of our ideal specification….but the price….for a bit more money we can have the .46 diamond, but it has a strong fluorescence….from what i can find, it only affects the diamond when exposed to black lights, so if it really doesnt effect the diamond is an important quality to check for and decide for a diamond or against it….the .46 carat marquise, is EVERYTHING we want, it is my ideal specifications to a T, l/w ratio, depth, table, no cutlet, H color, SI1 clarity, it is compeletly eye clean, minimal and not noticeable bow-tie, and it is within our budget if we splurge a little…..only $100 more then we originally wanted to spend and $30 more then the other .31 diamond, which has higher qualities, its a D color, VVS1, excelent cut….and no fluorescence….the .46 carat has a strong blue fluorescence, which from all i can find makes the stones appear whiter, and the blue color will only show up in like a black light or tanning bed, and all my research is showing that it knocks the price off higher priced diamonds because it is considered an undesireable traight, even though it does not affect the overall quality of the diamond….but it increases the price of like a j-k diamond or below because it bumps up the color rating a notch or two….
would you buy a diamond with a fluorescence rating, or not?
if you have a diamond that fluoresces, can i see a picture, and if you do unless its exposed to black lights or tanning beds, do you notice the color change at all????
if you wouldnt ….why not??

@kansas_nurse: I would, for my upgrade i am looking at a cushion cut, I color with medium blue fluor. Because a) it would make the stone look whiter when you see it for lower colored stones, and b) its really nice and cool when you can see the diamond under the sun, and a you might be able to see a blue hue.
personally I don’t think blue fluor is a bad trait, but for some it is undersirable and because of the blue fluor diamonds are cheaper too. I’m trying to find you a link to show you the blue flour

Yes, fluroescence can be great when you have a more-yellow stone, I would say I and below. It can make it look whiter, but I dont think faint fluor is necessarily a bad thing even in an E or F! Its personal preference.

I actually didnt know much about Fluroescence and was reading it just the other day. Apparently, you are correct with the black light – BUT I did read that it is sometimes preferable in diamonds with a H or higher rating that might have some yellow, because the fluorescence supposedly masks any yellow. In a higher quality colorless diamond, I believe Fluorescence is considered a “flaw”. I say if the diamonds looks good to the naked eye – it doesnt matter

I have heard similar that fluroescence can actually have a positive effect on a stone with a colour grading G+ – because the fluroescence tends to be cool in tone (blue) it offsets the warmth of, say, the H colour making it appear more white.
I have heard it’s only a problem (sometimes) with stones that are D-F, and in those cases it’s important to actually see the stone and inspect it in varous lights, especially sunlight because it’s not always going to be the case that the fluorescence is a bad thing at all.
I would say go for the stone you’ve been looking at – but make sure there is a return policy just in case you do find that you don’t like the look of the stone (probably unlikely I would think)

If the ring has high fluorescence it will glow in the dark, as in, if you’re in a dimly lit restaurant. I know a girl who has a beautiful 2 carat diamond solitaire and it literally glowed in the dark when we went out to dinner a couple of months ago. It made it look like a decoder ring or cracker jack style ring.

Mine flouresces like a raver’s glowstick under a blacklight. There is no difference otherwise. It’s an old ring (his great-grandmother’s from over a hundred years ago)
I squealed with glee when I saw that it flouresces (we were at a science center. People were giggling at me)

I LOVE your ring. Sort of jealous I didn’t consider solitaires. Six prongs, is that a knife edge.. oh swoon…

Fluorescence is only an issue if:
1) You don’t like the look of it glowing blue in strong UV light (like at a club)
2) The stone is one of the very few that are negatively affected by the fluoro. This means that in any kind of UV light (near the sun), it has a hazy/cloudy look.
So, if you’ve seen it and like it, there’s no problem!

@kansas_nurse: Hi, my diamond has a strong fluorescence and I really can’t tell what effect it has on the diamond. I really don’t notice a color change whether I’m indoors or out or if it’s day or night. I have an E color so I guess it’s supposed to have a yellowing effect but I sure can’t tell.

Faint florescence is ok, but sometimes strong can make it apear a bit cloudy in less than perfect lighting. Not just under UV lights, but if you’re at a restaurant or happy hour and the lights are dim it will appear dull without much sparkle. I would be ok with a faint or medium florescence, but would steer clear of strong.

thanks everyone for the advice, we are trying to do more research on the subject matter, and from what im finding it is mainly the yellow fluorescence that is making the stone less desireable, and this one has blue….im hoping to talk to a jewler today and find out more about it….its just soo confusing and i never even heard of it at all until we were looking at the diamond certification….and it is soo highly debated in the jewlery community itself….that its hard to find unbiased awnsers….
its becoming a very tough decision and really dragging this process out….
