Hey :)
Lovely post. Jade is such a beautiful stone. I hope to get some raw jade someday. Too often people try to sell you serpentine or whatever. Do you own some pieces or are you just an admirer as well?
I see that your post is currently missing some references for the information you quote. It is great that you source your images but I believe the images you used are copyrighted and should be used with caution.
Good Luck to you :) I hope to see you again soon on my tags of interest.
Raw jade is hard to find. I have two pieces with donut shape, like the one in the post, one of them is imperial jade. There are techniques to diference serpentine from jade but not everybody knows it.
I write the posts myself from different sources that I have read, seen on TV and even experts with whom I have spoken so quoting them can be a bit difficult, especially because they are old things that I do not remember well hahaha, I even think that I took the mortuary mask out of a National Geographic book. Still I will try to find some sources for future post.
Thank you very much for reading, commenting and voting! :D
