any person knows if its what vonsen is?

Looks more like Serpentine to me - a really pretty piece of serpentine that could cut up nicely.
Could be jadeite as well, but without some proper testing I would not be able to give you a definitive ID. Your best course of action if you need a solid ID is to take it to a local University and have then examine/test it and then they could tell you what you have.

My vote is in for 'Aventurine'. Quartz with fuchsite mica. Chrome in the fuchsite would afford the same blue-leaning green.

Nono its specific gravity is 2.88 and it cuts class like butter. so it has blue green and whit and orange and a dark green vein harder than the rest of rock since its protruding at fracture

look at this also

+++++UPDATE++++
i just struck this rock with a quartz and i got piezoelectric sparks, i may even think it is an aquamarine

The last one looks like silicified listwanite. The first one does not look like the Vonson nephrite that I have and looks nothing like jadeite even the not so great California jadeite from Clear Creek.

I went through the same problem last year,,, mine turned out to be Aventurine. The white bands were the real clincher. That and the fact that it was so easy to cut and polish. If you have the ability to polish a corner it may help you identify the rock. I really have to agree with the Aventurine post.

aventurine? with 2.88 specific gravity? never on planet earth.

Does it have a foliation orientation? Any indication of an adaxial or abaxial surface? Looks like the fabric of the rock is very this and that way, like it was stretched and then cracked and filled with quartz secondarily (small vein/dike). Maybe if you could gain some clues from its physical appearance you may be able to uncover some of the processes needed to form it, thus narrowing down potential options for identifying it as one thing or another.

If you whack two quartzes together hard enough they will spark. Just sayin'.

As an aside, Christos, I got a really pretty chunk of Aventurine from a landscaping place that was white, teal, darker green, cream and umber orange. It can happen!

Looking up Listwanite I see it is very similar to Aventurine in chemical composition, just some potassium and iron oxide thrown in. Silicified Listwanite is an awesome guess.

Silicified listwanite, educate yourself.

i cant see the carbonate in it plus it doesnt react to HCL.

it doesnt react to hcl . i can see beryl stratiation. i can see clear glassy veins in the fracture that make wierd crystal faces if you look close to it. plus look how the white vein is cut by green veins in attached photo

i dont think so. wouldnt it fizz when submerged in HCL?

are you gonna comment on HCL reaction or just act smart?
