I have preschooler and recently, my brother got him a set of invisible ink pens that have a small UV light attached to the cap.
I recently got an Edwardian 3 stone ring (estimated I-J) and I had suspected that one of the old mine pears had fluorescence as that stone looked so white when in direct sunlight. So, I took the UV light and played around with the ring and realized that the OMC in the middle as well as one of the pears had strong fluorescence. Once I turned off the light, I realized both of those stones also had phosphorescence as it continued to glow yellow/orange once the light was turned off.
So then I got curious as to the fluorescence of my other bands (as I have a bunch of bands with different size and shapes). Well, it turns out quite a few of them have fluorescence and they pretty much ALL also have phosphorescence.
It’s incredibly hard to capture this particular fluorescence color on camera but it’s actually pink and this one does NOT have phosphorescence.
Similarly, I realized that a bunch of the stones in my small tcw tennis bracelet have fluorescence and they all have phosphorescence except the ONE stone that also has PINK florescence (didn’t bother taking pics of all of the stones in the tennis bracelet as it’s quite a lot).
Lastly, I have a 2 ct GIA M asscher where GIA notes “none” for fluorescence. However, to my eyes, it actually has a very slight YELLOW fluorescence (also impossible to capture the actual color on camera) that appears to have faint pinkish phosphorescence.
All in all, I have no idea what to make of this and I am wondering if it’s whatever UV rays that are being used in these pens that are accentuating the fluorescence as well as phosphorescence??? It’s these cheap ones off of Amazon lol
Also wanted to add that I have 2 bracelets from VCA with pave on them as well as a few Cartier pieces with melee and NONE of them have any fluorescence (in total it’s probably about 100+ stones). I am wondering if these high end houses weed out any melee with fluorescence as I know that fluorescence in high color grade stones (DEF) is sometimes seen as a negative.
