Hello! This piece is very heavy, I didn't do the specific gravity test yet, if possible, please let me know if it's jadeite and how much this 370 gram stone might cost, thank you!

It is often impossible to identify something from a picture.
There are several things it could be.
We need more clues.
Shine a pen light behind it. Are the edges opaque or translucent?
Carry on with a specific gravity test.
Do a hardness test. Use a penknife and see if you can scratch it.

Thank you for your opinions and information! Knife didn't leave any scratches and there's a green glow around the led light if the sample is touched by it.

Specific gravity should be next.
Results?
Have a side polished, get a refractive index.
Can you get a photo of what you describe with the back lighting?

Thank you for the instructions, Barbra! I appreciate your time! The edges are opaque if a light is shone from behind, only when an LED light is directly touching the stone, the light penetrates the sample like 5 to 7 millimeters.
