Is It Really Hand-Carved?

This is a modern “carving” I’ve been researching. It is very cold and heavy like jade and the color seems appropriate. There are little specs of whiteness around the right eye which makes me suspicious. Plus I've seen so many slick, smooth pieces like this that are mass produced. It appears to have been dunked in some sort of coating. The seller called it antique but I certainly don’t believe that. My question is: Is it mass produced or, as advertised, hand carved? I haven’t found a good explanation of modern Chinese techniques of mass production. I assume imitation glass jade is poured into a mold, and there are probably other materials used that way. Those that I’ve seen offered in bulk look glassy. I have also seen that much is being done with lasers. Any thoughts most welcome.
