I love them too. Such a unique and wonderful texture when you hold them.

Wishing you good luck when you saw it.

I don't think that is a river stone. It appears to be similar to the actinolitic jade you would find underwater at Big Sur, California. It would make a nice suseiki (viewing stone). How much does it weigh and what did you pay for it?

I was thinking along a similar line, Nephrite. Easy to test...

As i was told, this stone was the part of a massive block. Its position was never affected during its time in the river which may explain its appearance.
It weighted 1,6kg and i paid 450$ for it. Which is a bit on a high end but its form factor is ideal to incorporate all natural surfaces as pendants backsides.

I would consider that doubtful. Jade doesn't naturally take on this type of polish.

Well, the stone cavities do not differ it their appearance from the other surfaces which would be extremely hard to achieve with any polishing techniques i am aware about.

It looks similar to other polished jade chunks I have seen offered. I am not sure what technique they use on them.

I am not sure where you are located, but all questions could be answered easily in a proper lab.

That comes to USD281.25/kg which is very expensive for that rock compared to Cassiar from B.C. or Siberian nephrite. Part of a massive block? Perhaps several hundred thousand years ago, but it has been a separate piece for a long time.

A jade rock could be smoothed and polished with diamond polishing pads and finished with a rotary diamond tool. If that rock were so polished, many hours of work would be required.

Neither you or I have actually inspected the rock, and I have seen some nephrite jades with a reflective polish without human action.

I'll trust you on that, but I have not. I have seen tons of roughly shaped and polished samples of nephrite for sale though.
