Hetian Jade carving possibly ancient?

I posted this on another jade forum and a member there who spends their free time studying jade carvings by microscope identifying the age of ancient jades by tool marks left behind thought this was possibly an ancient carving. I have some close up images and to my untrained eye this may be possible the lines I am seeing look uneven running randomly without the parallel marks left behind by modern diamond impregnated craving tools, but I have very little experience at this and don’t really know exactly what I’m looking for? Any thoughts on this from those more experienced.

 

Just judging by the cord an' little red 'ojime', it looks to be about ~7/8" diameter by maybe 3/16" thick...a dead white. Good close-ups; Quite an attractive piece...thanks!

 

I think the jade forum member may know better than us..... & I personally can't tell a thing from your close ups...
