The JADE thread!

I bought this bangle because I liked it. The seller says that is is nephrite which I don´t believe.
It was only 50 Euros. What do you think?
What kind of stone could it be? I doubt that it is dyed as the other half is white but of course I am not sure.
Your opinion?

Hi Uli! I think it may be calcite. I have a blue bangle with similar texture and color that is calcite and was inexpensive.
