Fluorescence

[lazybum9]

Hi guys,

I''m new to this forum and hope to buy a good diamond for my proposal ring. I''m still trying to understand how fluorescence affects my diamond. I would want to get a round H&A, D-F, VS1 & set it in a 5 claws setting. Pls advise if a faint fluorescence will affect the brillance of the diamond.

Thanks.

faint will have no effect. No need for concern.
medium fluor may create a violet glow in natural light, which some people find pleasant. It also *may* improve tha colour grade in lower colours such as I/J/K.
Very strong or "overblue" could have a negative effect but this is very rare.
Some people seek out med blue as they prefer it and think its a cool effect to possess.

nb. pls note this applies to blue fluor only.

Ditto to the above

I actually purposely seeked out medium flouro for my diamond to be because in the sun it will give a subtle violet glow and under a black light they glow blue hehehehe I like it but thats a personal thing .

Finally the thing that will most affect the diamonds brilliance is cut feel free to post some contenders when your ready .

One minor disagreement.

Very Strong Blue is often an incredible gift to the diamond. I showed a 2.28 E with strong blue yesterday. In the sunlight it exhibited a powder blue color that was beautiful beyond belief. This diamond was what the original "blue white" color was all about before it came to be so abused that the FTC declared in 1938 that it was no longer a usable term in the industry.

The crispness of the diamond coupled with the powder blue color literally left my client weak kneed.

Only in the less than 1% of diamonds that are overblues that become hazy and roilly out of doors do I consider fluorescence anything but a gift of additional beauty.

Oh Wink this sounds very beautiful !! Could you post pictures ?

Would a Medium to Strong Blue also increase visibly a diamond''s beauty under sunlight ?

thanks for clarifying Wink

- I agree it sounds lovely. I am currently buying a medium and hoping it will exhibit some of these characteristics.

Waow lablover!!!!!!!!!!!! your set is magnificent and the lavender blue that shines off your stone is simply breathtaking

Thanks for sharing !! I bought a RB G colour with medium blue according to the cert (in the DiamCalc it is indicated strong blue) fluorescence but I did not see it IRL yet...I hope it will show off this blue flashes in sunlight as well ! Impressive !

 

[kcoursolle]

It should be a small effect, but a lovely one when it is noticeable. I personally love a liittle blue flour in a high colored diamond!

It can, each must be looked at to determine the visual effect. I believe that this is one of the reasons that so many look down on fluorescence, it requires that they actually take the diamond outside to see what it looks like in the sun.

Wink

P.S. What does it mean, "J'ai vu le soleil bas, tach� d'horreurs mystiques"

My rudimentary French tells me that it is something along the line of, "I saw the low sun ??? of mystical horrors" I think the word tach provides the meaning and it is not in my head where I can access it.
