expert opinion on med yellow fluorescent stone

[donaldc]

Hi all!

Been looking at this site for a few months now while I try to decide what E-Ring to buy my (hopefully future fiance. Seen a few good diamonds come and go on this site, but haven''t found anything that jumped out. Finally found one that was great except for one thing, it has a medium yellow flour. AHHH!!! Any recommendations? Here are the specs for it:

round cut
1.03 G SI2 GIA cert w/excellent cut
measurements: 6.45-6.49x4.02mm

pol- excellent
sym- excellent
fluor- medium yellow

depth-62.1%
table-55%
crown-35*
pav-40.8*

Any thoughts? Price is pretty good, but is that because of the medium yellow flour? Thanks in advance for the help. I''ve loved reading all of your posts over the last couple of months!

Hi Don,

I honestly don''t have a clue how med. would affect it. This is really a question for the experts.

I would suggest messaging the Admin and ask him to change the title to something like:

That way you make sure the right people see it.

hey donaldc!

welcome aboard!

have you seen this diamond? what is the color? i can see medium yellow having a visible effect on any stone but at what point does one perceive it, i don''t know. i would definitely want to see it in person prior to purchase. (or have an excellent return policy)

I actually looked at a pear one time with yellow fluorescence. In regular lighting you couldn''t see anything, but it was interesting to see it under the black lights. Ultimately I took a pass on it because the advice I got was that even if I couldn''t see it, it would affect the resale value if I ever wanted to trade it in, and I wasn''t getting any sort of deal on it in the first place.

(This was all pre-PS; I''ll be curious to see what the experts have to say about this.)

Yellow fluo. sells at a discount except on fancy colored Diamonds...
If you see that it does not affect the face-up color of the white (G). you might have a good deal...
But be careful..., it can easily affect a colorless Diamond in some lighting''s....

 

[donaldc]

Thanks for the advice everyone!

So final question. Diamond is going for $4000. Good deal?? The salesman says that it is entirely eye-clean.

Thanks again!

One last thing. I''ve heard that resale value on yellow fluor is not good. This is sort of a "starter" e-ring, and I do plan on upgrading a few years down the road. If I get it, will I lose a lot of money on it just because of the fluor. I really can''t find too much info on yellow fluor, so any help would be GREATLY appreciated!

*ignore this, my computer is going crazy and I didn't see that the last post posted...sorry!*

 

[Ellen]

don, sorry more experts haven''t chimed in. Here''s my .02.

I would only get this stone if the place you''re getting it from offers a FULL REFUND, not store credit, with a good amount of return time. If the store offers an upgrade policy, make sure (get in writing) that THEY will take it back. (you won''t get much for it trying to sell it yourself, and you may have much trouble getting another jeweler to take it on a trade in also) Then I''d make an appt. with an independant appraiser, not anyone who sells jewelry. See what they say about it and go from there.

Can I ask, are you looking at this online?

I remember considering a diamond with yellow fluor on Blue Nile a while back. The price was a nice discount compared to similar size/color/clarity/cut stones. I was thinking it could be set in a yellow gold bezel and would make a nice pendant.

As for an e-ring, I guess you would have to see how you like the color in various lighting situations. I would suggest keeping it when you upgrade, and possibly have it reset into another piece of jewelry.

I''ve got mixed feelings about medium yellow fluorescence. On the one hand, it allows you to buy a good looking diamond at a good discount. On the other hand, its usually tougher to resell a diamond with medium yellow fluorescence.

If you''re going to keep the stone and enjoy it for its own beauty, I would say fine. If you''re planning on reselling, I''d say no. If you''re planning on upgrading with the same company and they''ll give you a fair trade-in on upgrade, I''d say fine.

I''ve found in actuality that medium yellow fluorescence usually has from no effect up to a half grade effect (lowering the color grade in indirect sunlight). Usually about a quarter grade is the average, which isn''t much of an effect on color or beauty.

Rich, thanks for chiming in.

Hi Donaldc

Yellow Fluorescence is usually an indication that the stone has a microscopic cloud. If the stone you are looking at has the Si2 grading based on the cloud.

IE; that the cloud is the reason for the grade, The stone may have a dull appearance.This is why the stones are avoided buy some diamond merchants.

Thanks for the comments everyone!

Ellen, yes I am looking at the diamond online.

Still haven''t decided what I''m going to do. I think I''m leaning more toward not getting it though. The yellow fluor still scares me a little too much.

So I guess I''m still looking...

Oh well!! Wish me luck!!!

If you''d like any help looking for a stone, just ask!

And I don''t know where you''re shopping, but I would recommend sticking with the many reputable vendors on here.

 

[donaldc]

Thanks Ellen!

I definately am just looking at ones here. This diamond is from James Allen.

As far as diamonds I''m searching for. All I know is that she wants around a carot, round brilliant, in a solitaire setting.

Thats all I have to go on. My main thing is probably the best cut I can get, with a budget around $4500-5000 for diamond and setting.

Thanks again!

See http://lgdl.gia.edu/pdfs/W97_fluoresce.pdf page 246 as the cause of yellow fluorescence is due to platelets (aggregated nitrogen), WHICH MAY manifest themselves as clouds, however the primary reason, I believe, that "yellow fluor" is avoided in colorless diamonds is that the more UV you pump in, like in bright sunlight, the "poorer" or more yellow, the color grade will appear, just the converse of blue fluorescence, which would make the stone appear whiter as you pump in more UV. see http://www.adamasgem.org/giafluor.html which is a critique of color grading fluorescent stones.

In general as the "clouds" may not be visible under 10x in weaker strength fluorescent stones..

,Surprizingly , GIA does not mention the COLOR of the fluorescence unless the magnitude falls into the medium to very strong range.

Call Jim or Josh and have it brought in and ask him too take it outside in sunlight and look at it.
If he says it has no effect you got a bargain, if he says it has a some effect you can then discuss how much.
You can also discuss the inclusion type and location at that time.
