Hi all!
I ordered two D color, 0.26CT HPHT diamonds from Ritani, along with a cheap UV light from Amazon to test for phospherence just for fun. I saw a post by Lindsay from Ada Diamonds showing how some HPHT diamonds have orange/yellow phospherence and also saw this GIA study about this.
One of the diamonds didn't react at all, even after holding the UV light to it for multiple minutes. The other one, however, glowed blue with not a hint of yellow. I tried to capture this with my phone. It glowed for about 3-5 minutes before getting dimmer. It did not have fluorescence, I think, since it didn't glow under the UV light but rather only after I turned it off. What could this be? Also very surprised that the other diamond with the same specs from the same lab does not exhibit this?
Super curious to hear your thoughts!
