hi!
it really needs to be determined in direct sunlight ...
are you able to provide a video clip, outside, in direct sunlight??
surely, she's got security. can security accompany her outside to make a quick video clip for you??
how about a window in the office that allows sunlight to stream in??
firstly, very important to know: what is her return policy??
secondly, unless it's in DIRECT sunlight, we won't be able to determine, visually, if the strong fluorescence has adverse affects, such as milkiness, haziness, oiliness...
thirdly, is this vendor in the united states or is it abroad?? where are you, generally, located??
to answer you question, with much reservation, the stone in both the videos appear okay. the lighting is an overhead office lighting, likely to be fluorescent
Thank you,
It’s from Lauren B located in NYC. It’s $13,700 includes the setting for 1.7 ct D color SI1 clarity. Their setting is usually expensive, like the pave setting in the picture costs around $2,500 to $2,900 depends on the metal, so the diamond itself is cheap compared to that price.
So far I am not impressed by the advice.
Direct sunlight is of no value.
I have posted an article here several times - if you want Big Fat Facets go to my HD site and read the 2 blogs on this topic.
OP post the diamonds cert or the parts concerning the clarity. If you can get the vendor to take a photo of the shade of blue fluoro - a cheap UV light is better than the proper lab UV tester.
Thank you sir for the comment. Attached is the GIA certificate of the stone. I have a question: not about this diamond but if the strong fluorescence affects the beauty of the stone (milky/hazy), does it show all the time or just under certain light? And if the vendor can provide a photo of this stone under the UV light, we can tell either it’s good or bad? What do you think about the stone from the those videos above? I personally think the stone isn’t sparkly. Is it true or not?
I get where your coming from Garry but only sunlight has the full range of UV and it is something a consumer will be looking at their diamond in.
I agree it is not the best lighting but it exists and telling someone hey spend 10k on a diamond but never look at it in direct sunlight is kinda bad.
I have seen a diamond that went bright blue in sunlight and shaded sunlight but not under most uv testers including the 380nm-390nm cheap ones and the one gia sells it did not.
slight disagree on sunlight because I enjoy it.Shaded sunlight. Direct sunlight is way too confusing and cut quality has more impact than fluorescence.

Eaxctly why I said to use a cheap one - they are better and more practical as they are frequencies that are also found indoors as they travel through windows - but I prefer really cheap ones that are more in the 410-390nm range

Agree with you on UV led lights the cheap ones are better.

Preparing them to look at what the diamond is projecting light on for a light show is better.

Sunlight through a window has a lot of common wavelengths that diamonds are reactive to.
One answer is ask them to put it in writing that the whole thing is returnable for a full refund if it is milky/hazy.
The videos look good. no large dark zones.
You would know it when you saw it.Thank you for the comment! How can I know if it appear milky? Just in person and if isn’t bright? When I look at the video the diamond is just so white. Is it because it’s a D color? I mean I’ve seen some diamond through videos and very lively and sparkly, but this one I don’t see it.

I agree with @Big Fat Facets
To assess for milkiness or haziness, I would expose the diamond to direct sunlight and view the diamond face up and from the side against bright background.
The article/thread you posted and strange/negative effects you mentioned apply to the ideal cut rounds. We are talking about OP's pear. Leaky elongated cuts and crushed ice cuts behave completely differently and do not show negative effects under direct sunlight like the ideal rounds do. In fact, those diamonds really shines and appear graceful under direct sunlight and your marquise in the photo proves this. Furthermore, I can make some assessment on cloudiness for that marquise in that photo. I do not see scattering of light inside the diamond and the diamond appears clear crystal-like. Therefore, it is not milky; am I wrong here?I can not remember how many times people have posted on this forum that their diamond looks dark or blue in sunlight. It happens mostly with diamonds that are top cuts, as I explain in thae article above.
This negative feature frightens people.
It is not related to fluorescence at all.
By all means enjoy the cool effects of looking at your own fluorescent diamonds in direct sunlight.
But to assess milky hazy cloudiness in fluorescent diamonds please do it in shaded daylight, up very close to a halogen lamp or some other type of light that emits a fair amount of near visible violet light.
All I ask is you not scare or confuse people by the strange effects of a diamonds seem in any strong single very small point light source.
But I do agree you with working with a strong single point small light source is not easy.
True. It is difficult to work with. But it is there everyday. Can be useful. Gotta learn how to use it properly.the sun is the strongest small point light source on earth
