I can't believe I haven't found concise and explicit information on how to tell the difference between nephrite and jadeite!!!
I know they are mineralogically different but look essentially the same and have the same refractive index. But how without guessing.
The only info on the internet is - "Ask an experienced jade trader, they can tell from 20 yards away" or "one is vitreous and one is greasy" or "one has a fibrous ,felt like structure and jadeite a more blocky cryptocrystalline structure". Well I don't have an electron microscope and I left my EDXRF, LA-ICP-MS and infrared spectrometer in the other car.
Somebody give me a link!!!
