Fluorescent Diamonds and Emeralds
Fluorescent Diamonds and Emeralds
In this video, I’m showing how anyone with even a cheap UV light can make some interesting discoveries within their own gemstone and jewelry collection. After I received my light in the mail, it kept my kids and I occupied for several hours testing various gemstones and minerals to see what would fluoresce and what wouldn’t. It was fun!
Thee UV Lights are great for classroom learning or hobbies can come in packs of 10 here:

Specifically I am demonstrating how well natural diamonds can fluoresce as well as different types of man made emeralds versus a natural emerald.
I Use the GIA as a regular resource whenever I am looking for well documented information on a specific type of gemstone, or even more specific articles such as he one I referred to about diamonds and fluorescence. You do not need to be a jeweler or gemologist to read their articles on their website.
I have a purple stone that glows green with the uv light. I also have a blue stone that glows green too.
You’ll probably want to invest a little more, maybe $30-$50, in a true UV light source like a Convoy S2 UV flashlight with a ZWB2 filter. The difference is absolutely dramatic. The light you have here is emitting around 395nm which is really just at the very edge of the UV range and has a very wide spectral bandwidth of FWHM around ~30nm, whereas a good Nichia diode source like the Convoy with a notch filter in front will be an exceptionally pure and intense (you must wear UV blocking eyeware when using it – it’s so intense it scares me almost as much as laser sources) source of 365nm radiation with a FWHM bandwidth of only ~10nm. It’s totally wild looking at things around the house, minerals, plants, etc. with a source like this because the UV is so truly invisible the only thing you’re seeing is isolated fluorescence. It will also be powerful enough to excite phosphorescence in the diamonds, which a 400nm never will. Highly recommend getting one.
hi mate was justlooking through some of my gemstones that i found and i have a diamond that i found and it is light blue fluoresent under uv light tho when the light is removed it is uv reactive and glows orange with the uv light removed is that normal??
One question, my necklace have a diamond in it and when i shine a UV light on it, it turns purple and not blue as u showed, what does it mean?
Many Videos show that Ruby Corundum will glow if real because of the high content of chromium, and glow less if the ruby has more iron in them, but will still glow. So when you said Synthetic Rubies glow, I think you should also note that real ones also react with the UV light, depending on the type of Ruby.
Don’t forget the ones that GLOW IN THE DARK!!!
Hi
bathe your nails don’t be dirty….
Hello, I understand that of all emeralds, only the one that shone red was real ??
I have an emerald, 11cts, when I put it under UV light, its top reflects a delicate purple and its color is green unchanged. Is it real or fake ??
An interestng video. However, some natural emeralds do fluoresce red under UV. I recently bought an emerald-in-matrix specimen from Afghanistan, and the emerald crystals fluoresce a very obvious medium red under a LWUV torch. These emeralds are high in chromium and very low in iron, hence the fluorescence.
