Observations under LWUV, Deep UV, and CPF Reactions
When inspecting a 5.44 ct diamond for origin, especially to confirm that it is natural, various advanced spectroscopic and luminescence techniques are employed. These include Long-Wave Ultraviolet (LWUV) fluorescence, Deep Ultraviolet (DUV) fluorescence, and Cross-Polarized Filter (CPF) reactions.

Unusual Longwave and Peculiar Shortwave Phosphorescence in Lab-Grown Diamonds
zhlédnutí 7Před 28 dny
I've never observed any longwave phosphorescence in lab-grown diamonds until now, which is unusual. However, I've come across it in these specimens, and the shortwave phosphorescence in this case is also very peculiar.

Identification of CVD Diamonds Using the CPF Method and Synthetic Diamond Screening Techniques
zhlédnutí 138Před měsícem
The CPF method is straightforward and cost-effective to implement, requiring only a set of linear polarization filters attached to a microscope. To utilize this method, position the suspected synthetic material between the cross-polarized filters and rotate it under transmitted light to observe birefringence. In this case, the diamond was kept stable and video was captured while rotating one of...

"Ultraviolet Reactivity: Distinguishing Natural and Synthetic Diamonds"
zhlédnutí 21Před 3 měsíci
Natural diamonds generally exhibit a stronger reaction when exposed to long-wave ultraviolet (UV) light compared to shorter UV wavelengths. Conversely, synthetic diamonds typically show more intense fluorescence under short-wave UV compared to long-wave UV. This discrepancy aids in distinguishing between natural and synthetic diamonds.

Hi, what kind of equipment are you using?
Thanks for sharing! The stone resembles a rough diamond, so it can be easily misidentified!
You need to have all the basic knowledge
Soooo, no one really can tell.
my stone test
awesome ❤
great post
Thank you for sharing this @Basil Gem Lab.
Please explain the details...
