UV light passes through thick glass and causes fluorescence in diamonds indoors.

To dispel the argument that UV light that causes color whitening in blue fluorescent diamonds does not pass through windows. This bathroom door is 10mm thick or 0.4 inches!
The center diamond is GIA Medium Blue. Clearly the diamonds are fluorescing.
What is more, the long wave frequency used for grading fluorescence has around half the effect as these simple cheap torches which work in the near visible range. It is for this reason that earlier tests (with the wrong light meters) are totally irrelevant.
This simple test shows that very long wave UV that is in the just or near visible range does pass through windows.

Can moissinite shows same effect ?

@faridhasansazali2256 11 месяцев назад

do some diamonds glow yellow under longwave uv light and glow blue under shortwave uv light?

Do Rough diamonds fluoresce with the UV light? or is it only the cut diamond?

@Muonium1 Год назад

this looks like 400nm light is that the case? have you ever seen any diamonds fluoresce a color other than blue and does 400nm excite phosphorescence in any diamonds or is it only shorter wavelengths?

How do i tell the difference between lab dimonds and real dimonds in earth

@heatherwinfree5054 8 месяцев назад

Natural diamonds have larger and overall more inclusions than lab diamonds and the inclusions will contain nitrogen, whereas lab diamonds don't. If you mean just by LOOKING at the diamonds though, you can't. They're chemically, physically, and optically THE SAME THINGS.

I have an important question. I have 2 princess diamonds that came out of some yellow gold earrings. They sink in water but when doing a dot test I can see through a bit.its my understanding that some facet cuts will allow you to see thru regardless when real. I have a video and pics if you would like to examine on my channel. Thanks

Or you could just save a lot of time and look up the optical transmittance of glass. Around 85% transparent at 365nm. Science.

I tried this with my friends, they saw my rings diamonds blue i saw them pink, i don’t know why

@Grateful.For.Everything 4 месяца назад

well….i think the World deserves to know why, as well! So you damn well better do the nerdy thing and find out why and tell us, cuz we wanna know just as much as You do 😉 Let’s all find out together!

Shining it through a glass window is irrelevant.

A lot of gemologists say that windows cut out the UV but they do not understand that near visible and visible violet create stronger blue fluorescence than shorter 365nm long wave UV that has no relevance to diamonds but is used for colored gem ID.
