The material?

Thanks to everybody's input. Now one thing is very interesting after I have read everybody's comments.

I thought this ax was made of some dark green nephrite. Larry seems to think it was made of serpentine. Anita seems to believe it was made of black granite.

I wonder if Pipan or Mr. Zhu has any thoughts about this. It would be great if Randy would render his opinions too.

Another interesting thing mentioned by Larry about abestos material from carving serpentine.

I agree that when serpentine stones were being carved, its dust if breathed into human lungs can be very dangerous. But it seems it would apply to the carving of nephrite too because there are abestos from both actionolite and tremolite.

I thought abestos are different forms of materials than nephrite or serpentine rocks or carvings.

Therefore, I wonder if it would be safe to keep any nephrite or serpentine rocks and jade carvings displayed at home.

Any scientists, geologists or safety officers out there would be welcome to make a comment.

Thanks.

P.S. There seem to be two schools of thoughts concerning the weathering: acid etched or sand blasting. It would be interesting if some examples showing both types can be shown here.
