How to tell if a diamond ring is real with a flashlight?
Excuse me, I'm curious about diamond rings and I've heard that a flashlight can help identify whether one is genuine or not. Can you explain the process in detail? Specifically, what should I look for when shining a flashlight on a diamond ring to determine its authenticity? Are there any specific angles or techniques I should use? And are there any other methods I can use to confirm if the diamond ring is real? I'd appreciate your expertise on this matter.
